Take a Tour of Intel Ireland
Functional Area: Diffusion
Hi, my name is Ann and I work here in the Diffusion area.

What Happens Here?In the diffusion area, wafers are heated up to high temperatures in the presence of oxygen. Silicon on the surface of the wafer is converted to silicon dioxide. This is similar to rust (iron oxide) forming on the surface of iron.
We put the wafers into a furnace . The furnace heats up the wafers to a very high temperature. We then introduce oxygen . into the furnace which combines with the silicon to form a layer of silicon dioxide. The wafers are allowed to cool down, removed from the furnace and moved on to the next step. We now move to the Implant area
