IPC: H01L21/02
Filed: 2001-08-27
Abstract: PROBLEM TO BE SOLVED: To solve the problem that a high-permittivity film is applied instead of a conventional SiO2 film when the film thickness of a gate insulating film is a 2 nm or less in terms of an SiO2 film, that suppression of a leakage current must be realized, that a thin film must be realized, that a threshold voltage is shifted due to the generation of a fixed electric charge, and that a drain current is dropped due to the deterioration of a mobility in a gate insulating film manufactured by a conventional technique. SOLUTION: The SiO2 film in 0.5 nm or more is formed in the interface between an Si substrate (a polycrystal silicon gate) and a high-permittivity insulating film, and a temperature in the formation of the SiO2 film is set at a heat treatment temperature or more in a later process. Consequently, as compared with the conventional SiO2 film, the leakage current is suppressed to 1/100 or less, and a field-effect transistor comprising the gate insulating film in the thickness of 2 nm or less in terms of the SiO2 film can be manufactured without generating fixed electric charges and without deteriorating the mobility. That is to say, the small power consumption and the large current of a fine field-effect transistor can be realized.
