WebPhotolithography is the standard method of printed circuit board (PCB) and microprocessor fabrication. Directed self-assembly is being evaluated as an alternative to photolithography. Photolithography is commonly used to produce computer chips. When producing computer chips, the substrate material is a resist covered wafer of silicon. WebDUV Photolithography There are significant differences between typical UV photolithography and DUV photolithography. Due to the shorter wavelengths used there is much higher absorption of energy in the standard novolak resist polymers, necessitating the use of very different polymer easy cozy wellness abbotsford https://shipmsc.com
