WebIn integrated circuit manufacturing, photolithography or optical lithography is a general term used for techniques that use light to produce minutely patterned thin films of suitable materials over a substrate, such as a silicon wafer, to protect selected areas of it during subsequent etching, deposition, or implantation operations. Web27 feb. 2024 · Thermal scanning probe lithography (tSPL) has been used to create patterns with sub-20 nm half pitch resolution. Pattern generation uses a thermally sensitive resist and spin coatable hard mask materials to transfer the resist patterns. Spin coatable materials permit users of tSPL to reduce time and cost of the patterning process.
