A photomask is made by exposing, or writing, the designer’s pattern onto a resist coated chrome ,mask, blank. The latent image in the resist is then developed to form the required pattern. This resist image acts as a ,mask, during the etching process. The pattern is transferred into the chrome film when the resist layer is removed.

For device ,fabrication,, this material has been used for several purposes, deposited by plasma enhanced chemical vapor deposition (PECVD) or atomic layer deposition (ALD). • Passivation • Insulation layer • Etch stop of a silicon-on-insulator (SOI) substrate • Hard ,mask, for dry etching • Substrate of microfluidics
1/10/1997, · Simulation and ,fabrication, of attenuated phase-shifting ,masks,: CrF(x). Kim E, Hong S, Kim KS, Jiang ZT, Kim DW, Lim S, Woo SG, Koh YB, No K. To acquire the required resolution for 248- and 193-nm lithography, a study of attenuated phase-shifting ,mask, (Att-PSM) technology is in progress.
A number of characteristics make chromium a popular contrast medium for high-quality ,mask fabrication,: - excellent adherence to glass and silica substrates; ... The contact must last for a few seconds (5") and then opened. At this point the ,mask, remains in the solution, while the aluminium electrode can be taken out of the bath.
Fabrication, of a new plastic photomask for the exposure process simplifies the shadow ,mask fabrication, process and results in higher resolution in the shadow ,mask, structures compared to the commercial ... and ,Cr, (30 nm). Scale bar in the shadow ,mask, image is 10 mm. Scale bars in multiple patterns images and close‐up images are 500 ...
The reported ,fabrication, procedure therefore gives a highly repeatable method to form well-aligned, uniform, and crystalline SiNWs of high density with controllable diameters below 100 nm. The use of ,Cr,/Au as a hard ,mask, blocking material will also be of great interest for the ,fabrication, of other Si nanostructures using the catalytic etching ...
• ,Fabrication, steps*: • Interference lithography • Definition of cavity by isotropic plasma ashing • Pattern transfer to ,Cr, hard ,mask, (wet and dry etching approaches) • Final DRIE of Ta substrate, desired results: • Cavity diameter 0.5 – 1.0 um • Aspect ratio > 2 • Ta pieces bonded to 6” …
Fabrication, of amorphous carbon phase ,masks Fabrication, of Si x N y membranes and aC film deposition. A 200 µm thick Si wafer with 120 nm thick low-stress Si x N y coating on both sides was used as base material. Optical lithography and etching methods for Si x N y and Si were applied to produce free-standing Si x N y thin films .
