00:01This tiny piece of silicon is more complex than any city on Earth.
00:06It contains more transistors than there are stars in the Milky Way.
00:11And yet, it fits on your fingertip.
00:14Right now, there are billions of them running the world.
00:17In your phone, your car, your refrigerator.
00:20But how do you build something this impossibly small, this impossibly precise?
00:25The answer is absolutely insane.
00:36In 1947, three scientists at Bell Labs invented the transistor.
00:42It was the size of your thumb.
00:45Today, a single chip contains over 100 billion transistors.
00:50Each one smaller than a virus.
00:53A human hair is about 70,000 nanometers wide.
00:56Modern transistors, three nanometers.
01:00That's 23,000 times thinner.
01:02Only a handful of facilities on Earth can make chips this small.
01:06The machines that build them cost over 150 million dollars each.
01:11These machines are so large, they require multiple cargo planes to transport.
01:16And so precise, they measure distances using the wavelength of light itself.
01:22The factories that house them, called fabs, are the most expensive buildings ever constructed.
01:29Some cost over 20 billion dollars.
01:33The air is 10,000 times cleaner than a hospital operating room.
01:38A single speck of dust could ruin everything.
01:41What you're about to see is the most complex manufacturing process ever created by humans.
01:48Let's break it down, step by step.
02:02It all starts with sand, but not just any sand.
02:06We need silicon dioxide, the purest form of quartz.
02:10This special sand is mined from only a few places on Earth.
02:14Australia, Brazil, and North Carolina have the richest deposits.
02:19The quartz is heated to over 2,000 degrees Celsius with carbon.
02:24This strips away the oxygen, leaving raw silicon.
02:28But this silicon is still only 98% pure.
02:33For microchips, we need something much, much better.
02:37Through a process called the Siemens method, the silicon is converted to gas, then deposited back as a solid, atom
02:45by atom.
02:47This creates polysilicon.
02:49Now 99.9999999% pure.
02:54That's nine nines of purity.
02:56To put that in perspective, this silicon is 1 billion times purer than gold.
03:03It's the purest material humans have ever created.
03:06Now comes the magic.
03:08A tiny seed crystal is dipped into a crucible of molten silicon heated to 1,400 degrees.
03:15As the seed is slowly rotated and pulled upward, silicon atoms arrange themselves into a perfect crystal lattice following the
03:24seed's structure.
03:26Over many hours, a massive cylinder of single crystal silicon emerges.
03:31This is called an ingot, and it can weigh over 200 kilograms.
03:36Every single atom in this cylinder is perfectly aligned.
03:40If even one atom is out of place, the entire ingot is ruined.
03:46The ingot is then sliced into thin wafers using diamond-coated wire saws.
03:52Each cut must be incredibly precise.
03:55These raw wafers are about as thick as a credit card.
03:59But they're far from ready.
04:01The surface is rough and scratched.
04:04Each wafer undergoes chemical-mechanical polishing.
04:08A combination of abrasive particles and chemical reactions that creates an atomically flat surface.
04:15The result is a surface so smooth that if you scaled it up to the size of a football field,
04:22the biggest bump would be half a millimeter tall.
04:26This mirror-like wafer will become the foundation for hundreds of individual microchips.
04:32But first, it needs to enter the clean room.
04:34The wafer is loaded into a sealed carrier called a FOUP and transported through the fab by an automated overhead
04:43system.
04:44Humans who enter must pass through air showers and wear full-body suits.
04:49Even breathing too hard could contaminate the wafers.
04:53The clean room is bathed in yellow light because the wafers are coated with light-sensitive chemicals.
05:00Normal white light would ruin them.
05:02Air flows constantly from ceiling to floor through HEPA filters, carrying away any particles before they can settle on the
05:12wafers.
05:12In a class 1 clean room, there's less than one particle per cubic foot.
05:18Your bedroom has about one million particles in the same space.
05:23Now the real magic begins.
05:25The wafer will go through over a thousand individual processing steps over the next three months.
05:31First, the wafer enters an oxidation furnace.
05:35At over a thousand degrees, oxygen reacts with the silicon surface, creating a thin layer of glass.
05:44This silicon dioxide layer is only a few nanometers thick, but it's critical.
05:50It will insulate the transistors from each other.
05:53Next, the wafer is coated with photoresist, a light-sensitive chemical.
05:59It's spun at high speed to create a perfectly even layer.
06:05This photoresist will act like photographic film.
06:08Where light hits it, the chemistry changes, creating a pattern we can use.
06:15The coated wafer is baked to harden the photoresist.
06:19Now it's ready for the most critical step in the entire process.
06:23It's time to meet the most advanced machine humanity has ever built.
06:28The extreme ultraviolet lithography system.
06:41This is the ASML EUV machine.
06:44It costs 150 million dollars, weighs over 100 tons and took 30 years to develop.
06:50It contains over 100,000 components from 5,000 suppliers across 40 countries.
06:58No single company could build this alone.
07:01Inside, a powerful laser fires 50,000 times per second at tiny droplets of molten tin.
07:08Each one smaller than a human cell.
07:11Each droplet is vaporized into plasma, reaching temperatures hotter than the surface of the sun.
07:18500,000 degrees Celsius.
07:22This plasma emits extreme ultraviolet light with a wavelength of just 13.5 nanometers.
07:30Perfect for printing nanoscale features.
07:34But EUV light is absorbed by everything, even air.
07:38So the entire system operates in a near perfect vacuum using special mirrors to guide the light.
07:44These mirrors are the flattest surfaces ever made.
07:48If scaled to the size of Germany, the biggest imperfection would be one millimeter tall.
07:54The EUV light passes through a mask.
07:57A glass plate with the circuit pattern we want to print.
08:01These masks cost millions of dollars each.
08:06The pattern on the mask is reduced four times and projected onto the wafer.
08:12Features that are 12 nanometers on the mask become 3 nanometers on silicone.
08:17The wafer sits on a stage that moves with nanometer precision, positioning accuracy of one millionth of a millimeter.
08:25Where the EUV light hits the photoresist, the chemical bonds break.
08:31The exposed areas become soluble and can be washed away.
08:36After exposure, the wafer is developed, like a photograph.
08:40A chemical solution dissolves the exposed photoresist, revealing the pattern beneath.
08:46Now we have a precise stencil on top of our wafer.
08:50But the pattern is only in the photoresist.
08:53We need to transfer it to the silicone itself.
08:57The wafer enters an etching chamber.
09:00Here, reactive gases are turned into plasma that chemically attacks the exposed silicone.
09:06The plasma ions bombard the surface like tiny missiles, carving away material atom by atom.
09:13The photoresist protects the areas we want to keep.
09:17The etch must be perfectly controlled.
09:20Too shallow and the features won't work.
09:22Too deep and we destroy the underlying layers.
09:26After etching, the remaining photoresist is stripped away,
09:31leaving behind our pattern carved into the silicone or oxide layer.
09:36The sequence, coat, expose, develop, etch, is repeated dozens of times.
09:44Each cycle adds another layer of complexity to the chip.
09:49Modern chips have over 100 layers stacked on top of each other.
09:54Each layer must align perfectly with the ones below, within a few atoms.
09:59Tiny alignment marks on the wafer are read by lasers to ensure each new layer lands exactly where it should.
10:06The margin for error is essentially zero.
10:10Between lithography steps, we also need to change the electrical properties of the silicone.
10:15This is done through ion implantation.
10:17High energy beams fire dopant atoms, like boron or phosphorus, into the silicone crystal.
10:26These foreign atoms change how electricity flows.
10:30By controlling where we add different dopants,
10:34we create regions that either have extra electrons or spaces where electrons can flow.
10:41This is how transistors are born.
10:44A gate electrode controls whether current can flow between the source and drain like a tiny switch.
10:51Remember, we are creating billions of these switches,
10:54each one just a few atoms wide, all working together in perfect harmony.
11:00After the transistors are formed, we need to connect them.
11:04First, thin films of metal are deposited onto the wafer surface.
11:08Copper interconnects, microscopic wires, are built layer by layer.
11:14They carry electrical signals between billions of transistors.
11:18If you could see a cross section, you'd find transistors at the bottom
11:22with a skyscraper of metal wiring above, sometimes 15 layers tall.
11:27Each metal layer must be polished flat before the next can be added.
11:32Any unevenness would cause the layers above to fail.
11:37From start to finish, a wafer spends about three months in the fab,
11:41passing through over 1,000 individual processing steps.
11:45So far we've turned sand into silicon, grown perfect crystals,
11:50printed with light hotter than the sun, and carved features smaller than viruses.
11:56But we're not done yet.
11:57Right now we have a wafer covered with hundreds of identical chips.
12:02They still need to be tested and separated.
12:04And here's the terrifying truth.
12:06Not all of them will work.
12:08A single atom out of place can kill an entire chip.
12:12The percentage of working chips, called yield, can be as low as 50% for cutting edge processes.
12:19Half of everything we made is garbage.
12:23When each wafer costs tens of thousands of dollars to produce, those failures add up fast.
12:29This is why advanced chips are so expensive.
12:32Let's see how we separate the winners from the losers and turn raw silicon into the chips that power your
12:38devices.
12:41Before cutting the wafer, every single chip is tested.
12:45A probe card with hundreds of tiny needles touches each die.
12:50These probes send electrical signals through the chip, checking if every circuit responds correctly.
12:57A full test takes just seconds.
12:59A wafer map is generated, showing which chips passed and which failed.
13:04Green means good.
13:06Red means that chip will never see the inside of a computer.
13:11Failed chips are marked with ink dots.
13:13They'll be discarded after cutting.
13:16Some companies sell partially working chips as lower tier products.
13:21A diamond tipped saw, spinning at 60,000 RPM, cuts the wafer into individual dies.
13:28Each cut is thinner than a human hair.
13:31The wafer is then broken apart along the score lines.
13:35What was once a single piece of silicon is now hundreds of individual chips.
13:40Robotic arms pick up each good die with incredible precision.
13:45These bare chips are fragile and must be handled in clean conditions.
13:49The die is attached to a substrate.
13:52A small circuit board that will become part of the final package.
13:56Adhesive or solder bonds them together.
14:00Microscopic gold or copper wires are bonded from the chip to the substrate, creating electrical connections.
14:07Some chips need hundreds of these wires.
14:10Advanced chips use flip chip bonding instead.
14:14Tiny solder bumps connect the chip face down to the substrate for better performance.
14:19The delicate chip is then encased in protective epoxy.
14:23This black material you see on finished chips protects them from damage and moisture.
14:29High performance chips get metal heat spreaders.
14:32Without them, the chip would overheat in seconds and destroy itself.
14:38Different applications require different packages.
14:41Some have pins underneath, others around the edges.
14:45Others use ball grid arrays.
14:47Packaged chips undergo final testing, including burn-in, where they are stressed at high temperatures to weed out early failures.
14:56Chips that pass are sorted by performance.
15:00The fastest become premium products.
15:03Slower ones are sold as budget versions.
15:06Same design, different price.
15:08Each chip is laser marked with identification codes, production dates, and specifications.
15:14Every chip can be traced back to its exact wafer.
15:18Finished chips are loaded into tape reels or trays.
15:22They are ready to ship to factories around the world.
15:27From a fab in Taiwan or Korea, these chips will travel thousands of miles to become the brains of phones,
15:34computers and cars.
15:35At electronics factories, the chips are soldered onto circuit boards alongside thousands of other components.
15:45Pick and place machines position components with incredible speed.
15:50Some can place over 100,000 parts per hour.
15:55The boards pass through reflow ovens where solder paste melts and solidifies, permanently connecting every component.
16:04And finally, these boards become the devices we use every day.
16:09The chip that started as sand is now running your entire digital life.
16:14From beach sand to silicon crystal, through light and plasma, chemistry and physics.
16:21A journey of a thousand steps, all on your fingertip.
16:34For 50 years, the number of transistors on a chip has doubled roughly every two years.
16:39This is known as Moore's Law.
16:43But we're approaching physical limits.
16:46When transistors are just a few atoms wide, quantum effects start to cause problems.
16:53Electrons can tunnel through barriers they shouldn't be able to cross.
16:57The switches that should be off start leaking current.
17:01Engineers are exploring new solutions, different materials, three-dimensional stacking, even using light instead of electricity.
17:10We're already stacking chips vertically, cramming more computing power into the same footprint by going up instead of shrinking further.
17:20Chiplet designs combine multiple smaller chips in one package.
17:24If one part fails, only that chiplet is lost.
17:28Not the whole thing.
17:29There's also a geopolitical dimension.
17:32Over 90% of advanced chips come from Taiwan.
17:36That concentration worries governments worldwide.
17:39Hundreds of billions of dollars are being invested to build new fabs in the US, Europe and Japan.
17:46A new chip race is underway.
17:48There are environmental challenges too.
17:51A single fab uses millions of gallons of ultra-pure water daily and consumes enormous amounts of electricity.
18:00The industry is working on sustainability, recycling water, using renewable energy and finding less toxic chemicals for manufacturing.
18:11Whatever comes next, whether it's AI, autonomous cars or brain-computer interfaces, it will all depend on chips even more
18:20advanced than today's.
18:21And somewhere right now, engineers are pushing the boundaries of what's possible, finding ways to fit just a few more
18:29transistors onto that tiny piece of sand.
18:32Every time you unlock your phone, search the internet or stream a video, you're witnessing the result of humanity's greatest
18:40engineering achievement.
18:42Over a thousand steps, three months of processing, billions of transistors, all working together, all measured in atoms.
18:50And it all fits right here.
18:52And it all fits right there.
18:53Now you know how microchips are really made.
18:55Microchips get really made.
