WebPhotolithography is the standard method of printed circuit board (PCB) and microprocessor fabrication. The process uses light to make the conductive paths of a PCB layer and the paths and electronic components in the silicon wafer of microprocessors . WebJan 1, 2014 · The technique enhances the sharpness of pattern by integrating the phase shifting scheme to photolithography, and have extended the capability of the lithography process. Phase shift lithography shares similar processes with traditional photolithography, e.g., resist coating and baking, light exposure, and resist developing. WebObjective Photolithography is the most critical process step in device fabrication. The main goal of photolithography is to replicate a pattern representing an integrated circuit component on the wafer surface. In this lab you will simulate the four key stages of photolithography that are typically carried out in an IC fabrication: Surface preparation … lifeprint 3x4.5 hyperphoto printer
