Patent ID: 7585771

Claim:
A method for manufacturing a semiconductor device, comprising: forming a layer of cobalt (Co) or a layer of dicobalt monosilicide (Co2Si) on a device-forming surface of a silicon substrate in a sputter apparatus, by utilizing a predetermined temperature profile; after said forming the layer of Co or Co2Si, elevating a temperature of said silicon substrate to a predetermined temperature T 2 , which is equal to or higher than 600 degree C.; and after said elevating the temperature of the silicon substrate to T 2 , forming a layer of monocobalt monosilicide (CoSi) on said device-forming surface of said silicon substrate at a temperature within a range of equal to or higher than T 2 , wherein, in said elevating the temperature of said silicon substrate to T 2 , within a temperature range between a highest reachable temperature T 1 of said silicon substrate in said forming the layer of Co or Co2Si and said temperature T 2 , a temperature of said silicon substrate is elevated at a temperature ramp rate of equal to or higher than 50 degree C./sec.
