Silicon Wafer fabrication

Description

These are the instructions for creating silicon wafers and their initial processing steps.

Recipes

The starting point for the silicon wafers is Sand or Quartz.

Step 1.0 Get at least 9 blocks of Sand or Quartz.

Step 1.1 Purify the Sand or Quartz into silica sand in the crafting table.

Purified Silica Sand	Sand	3
Purified Silica Sand	Quartz	8

Step 1.2 Use nine purified silica sand portions in the furnace to create a silicon ingot.

Step 1.4 Use a silicon block in the furnace to obtain a silicon boule .

Step 1.5 Use a silicon boule in the stonecutter to obtain twenty-five unpolished silicon wafers.

Step 1.6 Polish the unpolished silicon wafers in the chemical mechanical polisher.

Step 1.7 In this step, we will bombard the wafer with ions to insert them into the silicon. Take the silicon wafers to the ion implanter for doping. You have two options. You can create a P-type wafer using boron or indium or you can create N-type wafers using phosphorus, arsenic or antimony. To determine which to choose, check the bottom of this page for their applications.

Step 1.8 The implantation process disrupted the silicon crystal structure. To smooth and repair the silicon crystal, take the doped silicon wafers to the annealing furnace with an argon cartridge.

Step 1.9 To grow a layer of silicon dioxide take the doped and annealed silicon wafers to the oxygen furnace with an oxygen cartridge. The dielectric layer of silicon dioxide is an insulator; it will prevent electrons from passing through.

Step 1.10 Use the unwashed silicon wafers in the Wafer Washer to remove any impurities.

You now have a Silicon Wafer (P-type) SiO2 or a Silicon Wafer (N-type) SiO2. These are the starting components of semiconductor fabrication that fabs use. The Silicon Wafer (P-type) SiO2 can be used to create not-and logic gates (NANDs) or arithmetic logical units (ALUs). The Silicon Wafer (N-type) SiO2 can be used to create the controller chip.
