    摘要: A method of fabricating a complementary metal oxide semiconductor (CMOS) device, wherein the method comprises forming a first well region in a semiconductor substrate for accommodation of a first type semiconductor device; forming a second well region in the semiconductor substrate for accommodation of a second type semiconductor device; shielding the first type semiconductor device with a mask; depositing a first metal layer over the second type semiconductor device; performing a first salicide formation on the second type semiconductor device; removing the mask; depositing a second metal layer over the first and second type semiconductor devices; and performing a second salicide formation on the first type semiconductor device. The method requires only one pattern level and it eliminates pattern overlay as it also simplifies the processes to form different silicide material over different devices.

    摘要: A method is provided of forming a contact to a semiconductor structure. A current-conducting member is formed which extends horizontally over a first portion of a semiconductor device region but not over a second portion of such semiconductor device region. A first film is formed which extends over the second portion and only partially over the member to expose a contact portion of the member. A first contact via is formed in conductive communication with the contact portion. The first contact via has a silicide-containing region self-aligned to an area of the member contacted by the contact via. A second contact via is formed in conductive communication with the second portion, the second contact via extending through the first film.
