Latest Patents

Furuta's latest patents include a method of producing a semiconductor device. This device features an electrode portion formed on a wafer, with a passivation film deposited on the wafer except for the electrode portion. An insulating film is then applied only on the passivation film, creating a concave portion over the electrode. Conductive material is embedded in this concave portion, intended for bonding to a substrate. Another notable patent is a method of forming a silicide film on a substrate. In this method, a metallic silicide film containing silicon at a concentration higher than stoichiometric is deposited on a substrate. An aluminum or aluminum alloy film is then deposited on the silicide film, followed by a heat treatment that causes silicon precipitation from the silicide film to the aluminum, effectively lowering the silicon concentration.
