摘要:
A process for producing electronic device (for example, high-performance MOS-type semiconductor device) structure having a good electric characteristic, wherein an SiO2 film or SiON film is used as an insulating film having an extremely thin (2.5 nm or less, for example) film thickness, and poly-silicon, amorphous-silicon, or SiGe is used as an electrode. In the presence of process gas comprising oxygen and an inert gas, plasma including oxygen and the inert gas (or plasma comprising nitrogen and an inert gas, or plasma comprising nitrogen, an inert gas and hydrogen) is generated by irradiating a wafer W including Si as a main component with microwave via a plane antenna member SPA. An oxide film (or oxynitride film) is formed on the wafer surface by using the thus generated plasma, and as desired, an electrode of poly-silicon, amorphous-silicon, or SiGe is formed, to thereby form an electronic device structure.

A process for producing an electronic device material of a high quality MOS-type semiconductor having an insulating layer and a semiconductor layer with excellent electrical characteristics. A substrate incorporating single-crystal silicon as a main component is CVD-treated to form an insulating layer. The substrate is then exposed to a plasma generated from a process gas by microwave radiation from a plane antenna having a plurality of slots, to thereby modify the insulating film.
摘要:
The surface of an insulating film disposed on an electronic device substrate is irradiated with plasma based on a process gas comprising at least an oxygen atom-containing gas, to thereby form an underlying film at the interface between the insulating film and the electronic device substrate. A good underlying film is provided at the interface between the insulating film and the electronic device substrate, so that the thus formed underlying film can improve the property of the insulating film.
摘要:
In a process involving the formation of an insulating film on a substrate for an electronic device, the insulating film is formed on the substrate surface by carrying out two or more steps for regulating the characteristic of the insulating film involved in the process under the same operation principle. The formation of an insulating film having a high level of cleanness can be realized by carrying out treatment such as cleaning, oxidation, nitriding, and a film thickness reduction while avoiding exposure to the air. Further, carrying out various steps regarding the formation of an insulating film under the same operation principle can realize simplification of the form of an apparatus and can form an insulating film having excellent property with a high efficiency.

A process for producing an electronic device material of a high quality MOS-type semiconductor comprising an insulating layer and a semiconductor layer excellent in the electrical characteristic. The process includes: a step of CVD-treating a substrate to be processed comprising single-crystal silicon as a main component, to thereby form an insulating layer; and a step of exposing the substrate to be processed to a plasma which has been generated from a process gas on the basis of microwave irradiation via a plane antenna member having a plurality of slots, to thereby modify the insulating film by using the thus generated plasma.
摘要:
A projection is formed in a substrate by anisotropic etching and a transistor is contained in the projection. The central portion of the projection covered with a gate electrode is formed as a channel region, and drain and source regions are formed on both sides of the projection by oblique ion implantation with the gate electrode as a mask. Formed below the drain, source, and channel regions is an element isolation section having the composition of the substrate intact. This eliminates the need for an oxide insulating layer below the transistor for easy manufacturing. Carriers generated in the channel region by ionization by collision can also be discharged to the substrate.

An insulting film is modified by subjecting the insulting film to a modification treatment comprising a combination of a plasma treatment and a thermal annealing treatment. There is provided a method of enhancing the characteristic of an insulating film by improving deterioration in the characteristic of the insulating film due to carbon, a suboxide, a dangling bond or the like contained in the insulating film.
