To prevent peeling-off of a film in a solder connection pad of a semiconductor device, which peeling-off may occur due to thermal load and so on in the manufacture process, a pad structure is adopted in which a Cr film good in adhesiveness to either of a Ti film or Ti compound film and a Ni film (or a Cu film) is interposed between the Ti film or Ti compound film formed on a silicon or silicon oxide film, and the Ni film (or the Cu film) to be connected to solder. Further, to prevent peeling-off at the interface between the Ti film or Ti compound film and the silicon oxide film, the Cr film is formed in a larger area than the Ti film or Ti compound film.

A semiconductor device provided with a mechanism for recording information is intended to provide a highly reliable one time programmable memory and to provide one time programmable memories at a high yield. In a one time programmable memory, a state in which the electrical resistance is high is varied to another state in which it is low by silicifying a metal with silicon and matching the high resistance state (a metal/silicon separated state) and the low resistance state (a silicide state) to 0 and 1, respectively, wherein there is used an underlayer material which reduces the interfacial energy in the interface with the silicide layer, which constitutes the low resistance state.

There is provided a high-reliability nano-dots memory by forming the nano dots uniformly. Also, there is provided the high-speed and high-reliability nano-dots memory by employing a silicon-oxide-film alternative material as a tunnel insulating film. The nano-dots memory includes the tunnel insulating film and silicide nano-dots of CoSi2 or NiSi2. Here, the tunnel insulating film is formed by epitaxially growing a high-permittivity insulating film of HfO2, ZrO2 or CeO2 on a silicon or germanium substrate, or preferably, on a silicon or germanium (111) substrate. Also, the silicide nano-dots are formed on the tunnel insulating film.
