Fabrication of multi-level photoresist patterns in one-step lithography by using Cr/Ni multi-film thickness mask
The 3-D microstructure can be formed by using Multi-film thickness mask (MFT-mask) with single exposure and single develop. The intensity of the UV light getting through the mask increases as the thickness of the chromium film decreases. However, the ultra-thin Cr film makes the deposition and etchi...
