Latest Patents

Hiroshima holds a patent for a method of manufacturing through holes in a semiconductor device. This patent describes a process where first through holes of a relatively small diameter and second through holes of a relatively great diameter are formed in proper shapes by separate processes in a first layer insulating film. The second through holes are tapered toward a layer underlying the first layer insulating film. Initially, the first through holes are formed in the first layer insulating film and filled with plug electrodes. Subsequently, the second through holes are created, and a first conductive film deposited over the first layer insulating film is etched back to fill the first through holes with plug electrodes. Finally, residues remaining on the side walls of the second through holes are removed.
