This process is crucial in the electronic industry. The process begins by coating a substrate with a light-sensitive … See more Positive: light will weaken the resist, and create a hole Negative: light will toughen the resist and create an etch resistant mask. To explain this in graphical form you may have a graph on … See more Based on the chemical structure of photoresists, they can be classified into three types: photopolymeric, photodecomposing, photocrosslinking photoresist. See more Physical, chemical and optical properties of photoresists influence their selection for different processes. The primary properties of the photoresist are resolution capability, process dose and focus latitudes required for curing, and resistance to reactive ion … See more Microcontact printing Microcontact printing was described by Whitesides Group in 1993.
