WebDec 2, 2024 · As part of the photolithography process Canon's FPD lithography equipment uses a mirror-projection method that performs exposure using a reflective optical system with a large, high-precision concave mirror at its core. The mirror is large enough to expose large displays in a single exposure to produce seamless, high-precision panels. 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 …

Webgeneral, modern photolithography involves a procedure with five steps; wafer preparation, application of photoresist, pre-exposure bake, exposure, post-exposure bake, and development. In photolithography, a wafer is a thin slice of semi conductive material, such as crystalline silicon, that forms the base for the photolithographic process. WebPhotolithography represents the workhorse technology for device manufacture and has traditionally used a Hg or Hg–Xe discharge lamp as the radiation source.
