http://myplace.frontier.com/~stevebrainerd1/PHOTOLITHOGRAPHY/Week%202-3%20DNQ-CAR%20%20Photoresists_files/DUV.pdf WebIn electron-beam lithography you have a limited selection of resists. The positive resists PMMA and ZEP are polymers that are broken up by electron irradiation. After exposure, the smaller bits dissolve faster in the “developer”. This is a very simple contrast mechanism; there isn’t any complex chemistry as you find in photoresist.

One of the important characteristics of He + beam is, reduced backscattering leads to minimizing the proximity effects in contrast …
WebDue to similarity in name and nature, depth of field (DOF) and depth of focus are commonly confused concepts. To simplify the definitions, DOF concerns the image quality of a stationary lens as an object is repositioned, whereas depth of focus concerns a stationary object and a sensor’s ability to maintain focus for different sensor positions ...
