Class Information
Number: 216/40
Name: Etching a substrate: processes > Forming pattern using lift off technique
Description: Process directed to placing a mask on a substrate, coating, or depositing material over the mask and substrate, then removing the mask to remove the deposited layer on the mask, thus leaving the deposited layer in a pattern where the mask was not present, and etching using the pattern as a mask.
