Abstract
A method of photolithographically patterning a layer of a dielectric composition including a photosensitive polyimide provides patterned dielectric features that have vertical wall profiles that are free of distortions normally associated with high temperature production conditions and shrinkage of the dielectric composition. The method is useful in the production of integrated circuits and high density multiconnect structures.
