Abstract
A method of processing an insulating film containing voids associated with the increased semiconductor device density is performed. An insulating film containing voids is coated with another insulating film by spin-on technique to substantially close up the voids, followed by photolithography process. By the processing without adverse affects from the presence of voids, for example, an undamaged cover film can formed, which can contribute to greater reliability of semiconductor devices.
