Title: Apparatus for vapor-phase epitaxial growth
Inventor: FUKUI TAKASHI
IPC: C30B25/14
Filed: 1982-03-10
Abstract: PURPOSE:To obtain a stable and highly uniform crystal, by inserting a spiral pipe between the reaction tube and the vacuum pump at the exhaust side of the reaction tube, thereby keeping the pressure in the reaction tube at a definite level. CONSTITUTION:The reaction tube 4 and the vacuum pump 8 for exhaustion are connected with each other through a spiral pipe 10 and the needle valve 9. The shape of the spiral pipe 10 is defined by the formula 1X10<3=nl/s<=1X 10<5> (turn/cm) (n is number of turns of the coil; l is the total length of the coil; s is cross-section of the coil). The raw material gas, etc. are supplied from the raw material supplying system (S) to the reaction tube 4, and a crystal is grown epitaxitially on the substrate 6 placed on the succeptor 7 heated with the work coil 5. Since the small pressure variation in the reaction tube caused by the fluctuation of the exhaustion rate of the pump and that of the feeding rate of the gas can be eliminated by this process, the reproducibility of the crystal growth can be improved.

Title: Filling of connection hole of semiconductor device
Inventor: KOBORI YOSHIMASA
IPC: H01L23/52
Filed: 1998-02-19
Abstract: PROBLEM TO BE SOLVED: To surely substitute polysilicon which filled a contact hole with aluminum. SOLUTION: Between polysilicn which fills a plug section 14 and a TiN barrier metal layer 12, an AlTiSi local antireaction film 13 is formed. After that, heat treatment is conducted at 450 deg.C for five hours. During the heat treatment, the local antireaction film 13 prevents the formation of a local projection through a reaction between polysilicon in the plug section 14 and titanium of the barrier metal. The reason for this is that the local antireaction film 13 contains TiSi, so that even if a titanium silicon compound is produced, it attaches almost uniformly to the local antireaction film 13.

Filed: 1982-03-12
Abstract: PURPOSE:To prevent the spacing loss and track shift and to attain high recording density, by providing a pressing means which is inserted in a head window of a cassette and contacts a magnetic disc elastically. CONSTITUTION:A magnetic disc loaded in a cassette half 1a is rotated toward the arrow A, one end of a support member 6 of a pressing means 5 loaded at the side ridge of a head window 4 is fixed to the side ridge and a pressing piece 7 fixing a cushion member 9 at the lower surface is fitted to a free end.

Title: Manufacture of semiconductor device
Inventor: KOIWA YUKIO
IPC: H01L21/8249
Filed: 1998-02-20
Abstract: PROBLEM TO BE SOLVED: To shorten the manufacturing turn-around-time(TAT) of an IC by suppressing the quantity of heat for annealing performed for recrystallizing the surface of a semiconductor substrate by adjusting the concentration of a p-type impurity doping the semiconductor device to such a concentration that the surface of the substrate becomes amorphous. SOLUTION: When the crystalline state of the surface of a silicon semiconductor substrate 101 is restored through annealing, the surface is more easily recrystallized, when the surface of the substrate 101 is completely made to be amorphous. Therefore, the substrate 101 is doped with a p-type impurity by selecting the concentration of the impurity to such a concentration that the surface of the substrate 101 is completely made amorphous. As a result, the doping damages given to the substrate 101 can be remedied easily, and the quantity of heat of the annealing performed prior to an epitaxial film 102 is grown can be suppressed. When the annealing temperature is lowered, the quantity of thermal diffusion of each diffusion layer 104 can be suppressed. When the annealing time is shortened, the manufacturing TAT can be shortened.
