Our lithography services include two-stage, contact printing, SEM analysis, profiler, alpha pass, thin film mapping, as well as multiple wet etching chemicals and a plasma etching system.
What is the lithographic process?
The lithographic manufacturing process is very similar to printing a photo in a dark room. In radiography, an energy-sensitive material is placed as a thin coating on a piece of photographic paper. A negative is used to selectively transmit or block the energy that passes from a source to the emulsion. Light causes a chemical change in the emulsion that changes its properties in certain developers. The exposed image undergoes a chemical process and the emulsion is then fixed to stabilize it against further exposure by ambient light.
