metal lift off process - EAS
- The Metal Lift-Off Process generally refers to the process of exposing a pattern into photoresist (or different material), depositing a thin film such as a metal or dielectric over the entire substrate area, and then removing or washing away the photoresist and excess metal leaving behind metal only in the designated patterned substrate area.

An inverse pattern is first created in the sacrificial stencil layer (ex. photoresist), deposited on the surface of the substrate. This is done by etching openings through the layer so that the target material can reach the surface of the substrate in those regions, where the final pattern is to be created. The target material is deposited over the whole area of the wafer, reaching the surface of …
