Title: How To Make A CPU
Channel Name: RobertElderSoftware
Description: How to make a CPU from scratch (any% speedrun glitchless):
-
Get a rock: Find a suitable rock to extract silicon from.
-
Smash the rock: Break the rock to obtain concentrated silicon dioxide.
-
Purify the silicon dioxide: Refine the silicon dioxide to 99.9% pure silicon dioxide.
-
Further purification: Purify the silicon to 99.9999999% polysilicon metal.
-
Prepare polysilicon ingots: Place the polysilicon ingots into a crucible.
-
Heat the silicon ingots: Heat the silicon ingots to 1698 °K.
-
Create a monocrystal: Dip a small seed monocrystal into the molten silicon and slowly pull it out as it cools.
-
Cut the monocrystal: Cut the monocrystal into thin slices to obtain silicon wafers.
-
Doping (optional): Optionally dope the silicon wafers with Boron, Phosphorus, or another dopant.
-
Apply photoresist: Coat the wafer with photoresist.
-
Use a photo-lithographic mask: Shine a laser through a quartz mask with the desired circuit pattern onto the wafer.
-
Develop the photoresist: Develop the photoresist to reveal the circuit pattern.
-
Etch the wafer: Acid etch the exposed parts of the wafer.
-
Repeat processes: Perform iterations of epitaxy, doping, interconnect layers, polishing, and etching to build up features on the wafer.
-
Finish the wafer: Obtain a finished silicon wafer.
-
Cut into pieces: Cut the wafer into individual silicon dies.
-
Attach bond wires: Locate the pads on the silicon chip and attach bond wires or use the flip-chip method for modern processors.
-
Connect the chip: Use bond wires or solder balls to connect the chip package pins with the silicon die pads.
-
Completion: Congratulations, you have successfully made a CPU!
