Pre-develop bake for end point stabilization with photo-BCB polymers

The use of a bake prior to development stabilizes the develop end point of photo-BCB films and removes the time dependence of the develop end point. The elimination of this source of process variability enables the implementation of a develop process in which, for a given film thickness and set of bake conditions, the optimum develop time is a constant, and monitoring of the end point is unnecessary.
