Intermediate semiconductor devices and methods of reducing damage during back end of the line (BEOL) metallization and metal one (M1) layer integration scheme are provided. One method includes, for instance: obtaining a wafer having at least one contact region; depositing on the wafer a thin film stack having at least one layer of amorphous silicon (a-Si); performing lithography to pattern at least one opening; performing lithography to pattern at least one via opening and at least one trench opening; and removing the at least one a-Si layer. One intermediate semiconductor device includes, for instance: a wafer having at least one contact region; at least one first dielectric layer on the device; at least one second dielectric layer on the at least one first dielectric layer; and at least one a-Si layer on the at least one second dielectric layer.
