An inspecting method is capable of efficiently inspecting a wafer. According to the inspecting method, the chip area of a wafer is inspected for defects, and based on the results, a defect density D0p of each of peripheral-zone chips in the chip area which are located closely to the peripheral area of the wafer is calculated. A peripheral-zone chip with a high defect density D0p is selected, and an area in the peripheral area which is outward of the selected peripheral-zone chip is inspected for defects. Since only the area in the peripheral area which is located outward of the peripheral-zone chip selected based on the defect density D0p is inspected for defects, the wafer is inspected efficiently.

An ultra high-speed semiconductor device has a high-K dielectric gate insulator layer, wherein spread of impurities to a Si substrate from a gate electrode through the high-K dielectric gate insulator layer, and spread of oxygen and metallic elements from the high-K dielectric gate insulator layer to the Si substrate or the gate electrode are suppressed by arranging the high-K dielectric film sandwiched by nitrogen atomic layers on the Si substrate that is covered by an oxygen atomic layer.

A semiconductor device in which the insulation characteristics of an insulating film of multilayer structure including a lower-layer insulating film and a high-dielectric-constant film formed on the lower-layer insulating film are ensured, and a method for fabricating such a semiconductor device. A silicon oxide film or a silicon oxynitride film is formed on a semiconductor substrate as a lower-layer insulating film and part of the lower-layer insulating film is removed. Then a high-dielectric-constant film the dielectric constant of which is higher than that of the lower-layer insulating film is formed on the exposed semiconductor substrate and the lower-layer insulating film. If the lower-layer insulating film is a silicon oxide film, then a metallic compound not including chlorine is used for forming this high-dielectric-constant film. If the lower-layer insulating film is a silicon oxynitride film, then a metallic chloride can be used for forming this high-dielectric-constant film.

An insulating film made of zirconia or hafnia is formed on the surface of a semiconductor substrate. A partial surface area of the insulating film is covered with a mask pattern. By using the mask pattern as a mask, ions are implanted into a region of the insulating film not covered with the mask pattern to give damages to the insulating film. By using the mask pattern as a mask, a portion of the insulating film is etched.
