(MIBK) development. Such high PEB temperatures resulted in insoluble material (high NRT values) in unexposed regions in the 248 nm contrast curves. A post-exposure bake (PEB) is performed before developing, typically to help reduce standing wave phenomena caused by the destructive and constructive interference patterns of the incident light. In deep ultraviolet lithography, chemically amplified resist (CAR) chemistry is used. Meer weergeven In 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 Meer weergeven A single iteration of photolithography combines several steps in sequence.
