To provide a semiconductor device that enables to suppress a defect density of a gate insulating film of an MISFET, gain a sufficient electric characteristic thereof, and make an Equivalent Oxide Thickness (EOT) of the gate insulating film 1.0 nm or less. The MISFETs are formed to have the gate insulating film formed on a main surface of a silicon substrate, and a gate electrode formed on the gate insulating film, wherein the gate insulating film includes a metal silicate layer formed by a metal oxide layer and a silicon oxide layer and the metal silicate layer is formed so as to have concentration gradients of metal and silicon from a silicon substrate side toward a gate electrode side.

A method of manufacturing an element having a microstructure of an excellent grating groove pattern or the like is obtained. This method of manufacturing an element having a microstructure comprises steps of forming a metal layer on a substrate, forming a dot column of concave portions on the surface of the metal layer and anodically oxidizing the surface of the metal layer formed with the dot column of concave portions while opposing this surface to a cathode surface thereby forming a metal oxide film having a grating groove pattern. When the interval between the concave portions of the dot column is reduced, therefore, a linear grating groove pattern having a large depth with a uniform groove width along the depth direction is easily formed in a self-organized manner.

摘要:
After the surface of the substrate is cleaned, an interface layer or an antidiffusion film is formed. A metal oxide film is built upon the antidiffusion film Annealing is done in an NH3 atmosphere so as to diffuse nitrogen in the metal oxide film. Building of the metal oxide film and diffusion of nitrogen are repeated several times, whereupon annealing is done in an O2 atmosphere. By annealing the film in an O2 atmosphere at a temperature higher than 650° C., the leak current in the metal oxide film is controlled.

A nitride-based semiconductor element capable of effectively preventing a nitride-based semiconductor layer of a first area from cracking and reducing the degree of warpage of a substrate is obtained. This nitride-based semiconductor element comprises a first region formed on a prescribed region of a substrate and provided with an element including a first nitride-based semiconductor layer having a prescribed thickness and a second region formed on a region of the substrate other than the first region and provided with the first nitride-based semiconductor layer with a thickness smaller than the thickness in the first region. Thus, strain easily concentrates to the second region provided with the first nitride-based semiconductor layer with the smaller thickness, whereby strain of the first region provided with the element is relaxed.
