Title: Dry etching method
Inventor: FUJII HIROSHI
IPC: H01L21/3065
Filed: 1986-05-27
Abstract: PURPOSE:To enable fast dry etching even by low energy by directly forming a deposit layer acquired by decomposing and polymerizing an etching gas prior to etching on the surface of a semiconductor substrate or the surface of a light transmitting substrate oppositely faced to said substrate. CONSTITUTION:NH3 gas is caused to flow into an etching chamber 1 while an silicon substrate 3 is irradiated by a laser. NH3 molecules absorb the laser and decompose, and an silicon nitride film is shaped onto the surface of the silicon substrate. A gas in the chamber is replaced with SF6 gas. The polymerization product 3a of SF6 gas is deposited on the surface of the silicon nitride film through glow discharge or microwave discharge. The silicon substrate 3 on which a reaction product is deposited is irradiated by the laser from a light-introducing window 4. The nitride film irradiated by the laser is optically pumped and the temperature of the nitride film is elevated, SF6 gas and the polymerization product are excited and decomposed near the nitride film, and fluorine atoms abounding in reactivity are generated and the silicon nitride film is etched.

CONSTITUTION:A WN film 3 and a W film 4 are formed one after another, by using a high-frequency (RF) sputtering method, on the whole surface of a GaAs substrate 1 on which an n-GaAs active layer 2 has been formed. Then, a resist pattern 11 for gate-electrode formation use is formed in a prescribed region of the W film 4; a reactive ion etching operation is executed by making use of the resist pattern as a mask; a two-layer gate electrode 10 composed of the WN film 3 and the W film 4 is formed. A mixed gas of SF6+CF4+H2 (a partial-pressure ratio of hydrogen gas is 10%; SF6:CF4=4:1; a gas pressure is 10Pa) is used for the RIE; a high-frequency electric power is 100W. Under these etching conditions, an etch rate of the WN film 3 and that of the W film 4 are nearly equal. Consequently, a cross-sectional shape of the two-layer gate electrode 10 can be processed to be rectangular, highly accurately.

Abstract: PURPOSE:To improve the characteristics of an ONO film to be used in a capacitor dielectric film. CONSTITUTION:After a polysilicon 12 for a lower electrode, a natural oxide film 13, and a silicon nitride film 14 are formed on a silicon substrate 11, the upper part of the silicon nitride film 14 is subjected to thermo oxidation to form a top oxidized film comprising the two layers of an oxynitride film 15 and a silicon oxide film 16. Then the silicon oxide film 16 on the top layer of the top oxide film is subjected to dry etching and removed by using an aqueous solution of hydrogen fluoride, an ONO film comprising the natural oxide film 13, the silicon nitride film 14, and the oxynitride film 15 is formed, and a polysilicon 17 for upper electrode is formed. Since the silicon oxide film 16 has a lower relative permittivity than that of the oxynitride film 15 with also inferior insulation, elimination of the silicon oxide film 16 increases the capacitance of a semiconductor device having the ONO film as the capacitor dielectric film and decreasing leakage current.

Title: Deoxidation composition
Inventor: AOKI MOTOHISA
IPC: A23L3/3436
Filed: 1979-09-26
Abstract: PURPOSE: To obtain a deoxidation composition which is in a group having a large amount of the carbon dioxide and composed of the iron powder, the metal halide and the calcium aluminate hydrate and which is effective to preserve the foods, the fur and the like.  
     CONSTITUTION: The iron powder uses the fine grains or the powder such as the reduced powder, the electrolyzed powder and the like having preferably the grain size of about ≤10 meshes. The metal halide uses the NaCl, HCl or the like and promotes the deoxidation of the iron powder, which is necessary about 0.0001W 1pt.wt. to one pt.wt. of the iron powder. And calcium aluminate hydrate uses practically 3CaO.Al 2 O 3 .3CaSO 4 .32H 2 O among each kind of compositions. These compositions absorb CO 2  and discharge water. On the other hand, the iron powder generates H 2  with the free water, and a large amount of CO 2  is turned into the carbonic acid to accelerate the generation of H 2 . Accordingly, the amount of free water is reduced by use in combination with the above-mentioned hydrate, and a slow supply of free water is possible with discharge of free water. Thus the danger of explosion is reduced to realize an effective deoxidation under existence of CO 2 . And the weight percent is set to 1:0.01W10 between the iron powder and the hydrate.
