CMOS Inverter Manufacturing Flow: Part 1 Wafer Start …
6.2.1 Active Photoresist Pattern. The CMOS integrated circuit manufacturing process starts with a single crystal silicon wafer (p-type for this inverter). First, a silicon dioxide (SiO 2) layer (pad oxide) is thermally grown on the single crystal silicon surface (~20 nm).A silicon nitride (Si 3 N 4) layer (~300 nm) is deposited on the pad oxide using low …

MEMS Fabrication Process | SpringerLink
For an evaporation process, you place your wafer inside a vacuum chamber along with a block of the source material, such as gold. The source material is then heated to boiling and begins to evaporate freely in the vacuum. As it condenses, it falls onto the surface of the wafer, creating a uniform film of metal.

MEMS Manufacturing Process | What Is MEMS?
Wafer Bonding. Wafer bonding is a term that means connection, attachment, or joining, and as suggested by the meaning of the term, it is a process of joining wafers or dissimilar materials together. In the MEMS manufacturing process, this is called substrate bonding, and there are two methods: direct bonding and anodic bonding.
