Building a Fab

• Construction of a Fab involves building the structure and the cleanroom inside.
• The building process is complex and can take several years to complete.
• It involves several critical components, including electricity, water, dust filtering, and transportation.

Electricity

• The capacity distribution and handling of electricity is essential for a Fab.
• Loss of power could cause significant damage and financial losses.
• Intel's Arizona location used 2 billion kilowatt hours in 2023, self-generating 11 million kilowatt hours through solar.
• Intel uses a special structure installed on the roof for power distribution, requiring a large crane to install.

Cranes

• A large crane is needed to place the special e-house on top of the Fab building.
• The e-house weighs approximately 150,000 lbs.
• Intel uses the Liber 13,000 LR 13000 crane, which has a 3,000 ton capacity.
• It is the largest crawler crane in the world.
• The crane can lift about 2,000 Porta-Potties simultaneously.

Water

• Fabs use a significant amount of water to support systems like scrubbers, cooling towers, cleaning wafers, and maintaining a clean environment.
• Intel's Arizona location has two facilities for water treatment and recycling.
• One facility recycles more than 9 million gallons of water per day.
• The other facility has treated more than 5 billion gallons of water since 1995.

Cleanroom

• Cleanrooms are necessary to keep dust, skin particles, eyelashes, and hair out of Intel's wafers.
• A single hair strand can potentially cause tens of thousands of dollars in damage.
• Cleanrooms are kept clean by filtering the air and exchanging it about six times per minute.
• Workers in cleanrooms must wear bunny suits.

Automated Super Highway

• The Automated Super Highway (ASH) is a system used to transport wafers throughout the Fab.
• It is a network of tracks that connect different factories.
• The system uses overhead hoist vehicles (OHVs) that carry front opening unified pods (FOPs).
• Each FOP contains one lot or 25 12-inch wafers.
• The ASH allows Intel to have flexibility in how they run production, essentially creating one large mega-factory.

Fabrication Process

• The semiconductor manufacturing process is complex and can take over a month to complete.
• It involves many steps, including:
  • Lithography
  • Etching
  • Metal Deposition
  • Planarization

Lithography

• Lithography is the process of transferring a pattern onto the wafer using light.
• This process uses photo resists, masks, and developer chemicals.
• Photo resists are light-sensitive materials that are applied to the wafer.
• Positive photo resists are weakened by light and become soluble to the developer.
• Negative resists resist etching and act as a mask against light.
• The wafer is exposed to light through a mask, which is a pattern that defines the desired features.

Etch

• Etching is the process of removing material from the wafer.
• There are two main types of etching: wet etching and dry etching.
• Wet etching uses chemicals to remove material.
• Dry etching uses plasma to remove material.

Metal Deposition

• Metal deposition is the process of adding metal to the wafer.
• This process can be used to:
  • Form transistors
  • Form interconnects

Planarization

• Planarization is the process of smoothing the surface of the wafer.
• This step is necessary to prepare the wafer for the next layer of processing.

Ion Implantation

• Ion implantation is a process that involves shooting ions into a material, typically silicon.
• This process is used to dope silicon.
• Doping silicon changes the electrical properties of the material.

Tools

• There are many different types of tools that are used in a Fab, including:
  • Deposition tools
  • Etch tools
  • Lithography tools
  • Clean tools
  • Polish tools
  • Ion implantation tools
  • Inspection tools

Diffusion Furnace

• A diffusion furnace is used to heat the wafer and change the composition of silicon.
• It is used to electrically activate impurities introduced by ion implantation.
• It can also be used to drive dopant deeper into a film layer.
• Intel uses vertical diffusion furnaces as they are more space efficient than horizontal furnaces.

Ion Implantation

• Ion implantation is a process that involves shooting ions into a material, typically silicon.
• This process is used to dope silicon.
• Doping silicon changes the electrical properties of the material.
