Question 25

What are the steps in the creation of a CPU?

Answer 25

1. Deposition - when new layers of material are deposited onto the wafer?
2. Exposure - photoresist is applied, areas of the photoresist are exposed to UV light, and exposed areas are removed.
3. Etching - when unprotected areas of material are etched away using various chemicals.
4. Testing - the wafer is inspected to make sure everything is working on the microchip
