ABSTRACT:
This invention relates to poly(acetylene) films having localized zones of a material other than poly(acetylene) with modified optical and electrical properties. The films are formed by selectively irradiating discrete areas of a film of a precursor polymer followed by heating of the irradiated precursor polymer to transform the non-irradiated areas into poly(acetylene). The resultant product has localized zones of modified electrical and optical properties which are useful in the semiconductor industries and in optical devices.
