Abstract: The present invention provides a fuse of a semiconductor device and a method of forming a fuse of a semiconductor device. The method of the invention includes forming an underlying metal conductor on a semiconductor substrate, forming an insulating film over the underlying metal conductor, and selectively etching regions of the insulating film. One of the regions of the insulating film is etched to form a via contact region exposing the underlying metal conductor. A second region is etched to form a groove in the insulating film for the fuse metal. Metal is buried within the second etched region of the insulating film and the via contact region to respectively form a fuse metal pattern and a via contact metal layer. The fuse metal pattern can be formed from copper and/or tungsten.

Abstract: Bonding pads for integrated circuits include first and second spaced apart conductive layers, a third continuous conductive layer between the first and second spaced apart conductive layers and an array of spaced apart insulating islands in the third continuous conductive layer that extend therethrough such that sidewalls of the insulating islands are surrounded by the third continuous conductive layer. A fourth continuous conductive layer also may be provided between the third continuous conductive layer and the second conductive layer and a second array of spaced apart insulating islands may be provided in the fourth continuous conductive layer, that extend therethrough, such that sidewalls of the insulating islands are surrounded by the fourth continuous conductive layer.

Abstract: A method for manufacturing a semiconductor substrate structure wherein a comprising the steps of defining bulk transistor and SOI transistor areas, the bulk transistor area disposed on a lower single crystalline silicon layer, and the SOI transistor area diposed on an upper single crystalline silicon layer. The method characterized in that a spacer is formed on a portion of the bulk transistor area which covers a sidewall of the SOI transistor area, a first conductive well is formed in the lower single crystalline silicon layer and a well oxide layer is formed over the first conductive well region, a second conductive well is formed in the lower single crystalline silicon layer between the SOI transistor layer and the first conductive well, and the first conductive well is rediffused.
