    Abstract: A process for forming an image with a positive resist using a polymer containing dimethylglutarimide units. The polymer is sensitive to both electron beam and light radiation, has a high glass transition temperature, a high temperature resistance, and is capable of very fine spatial resolution, very suitable for micro circuitry processings.

    Abstract: 1515330 Electron sensitive polymers INTERNATIONAL BUSINESS MACHINES CORP 5 Dec 1975 [29 Jan 1975] 49960/75 Heading G2C Positive resist masks are formed by exposing a supported film of a non-crosslinked polymeric material to electron beam radiation in a predetermined pattern so as to degrade the polymeric material in the exposed areas, and removing the degraded products in the exposed areas. The polymeric material used is selected from (1) polyalkyl methacrylates and copolymers of alkyl methacrylates with halogen - or cyano - containing monomers and (2) post halogenated derivatives of the polymers in (1). The coated polymers may be baked prior to exposure and also after development.
