    摘要: In a silicon substrate, impurity diffusion layers, serving as source and drain regions, are formed to be separated from each other. A gate insulation film is formed on the silicon substrate between these source and drain regions. The gate insulation film is a silicon oxide film containing Cl having concentration of more than 1.times.10.sup.18 atoms/cm.sup.3 and less than 2.times.10.sup.20 atoms/cm.sup.3, and the gate insulation film is formed on the silicon substrate by low-pressure CVD. A gate electrode, formed of a polysilicon layer, is formed on the gate insulation film. An inter-level insulation film is formed on a resultant structure. A contact hole is formed on each of the source and drain regions of the inter-level insulation film. A drain electrode is formed on the inter-level insulation film, and connected to the drain region through the contact hole. A source electrode is formed on the inter-level insulation film, and connected to the source region through the contact hole.

    摘要: A plurality of wafers are placed on a boat, and the boat is inserted into a reactor. The reactor is heated by a heater, thereby heating the inserted wafers. Then, air is supplied between the reactor and the heater through the fan nozzles of a fan unit, thereby cooling the heater quickly at a rate of 17.degree. C./min. PH.sub.3 and SiH.sub.4 gases are introduced into the reactor through first and second gas nozzles, only while the average temperature of a peripheral portion of each wafer remains 30.degree. C. lower than that of a central portion of the same. Thereafter, when the temperature difference between the peripheral and central portions has become lower than 30.degree. C., the supply of PH.sub.3 and SiH.sub.4 gases is stopped. Thus, a polycrystal silicon film is formed on each wafer.

    摘要: A heat treatment apparatus having a heat treatment boat with a plurality of wafers held thereon, which is to be loaded in a reaction vessel which has one end opened. Once loaded, the boat effects a seal of the reaction vessel, in preparation for subjecting the wafers to heat treatment. The boat also has a heat-insulator disposed on its lower end for heat-insulating the interior of the reaction vessel during the heat-treatment. The heat-insulator includes composite plates having a metal film layer on an upper surface for reflecting heat rays generated during the heat treatment of the reaction vessel, and a cylinder enclosing the composite plates. Thus, sufficient heat-insulating effect for the heat treatment can be obtained, and stable heat-treatment can be conducted with the sufficient heat-insulating effect secured. Furthermore, the generation of particles can be suppressed, and yields of the heat treatment can be improved.

    摘要: The object of the present invention is to assuredly merge adjacent coating liquid lines when a coating liquid is applied on a surface of a substrate by a so-called scan coating. The coating is performed while the wafer W is oriented to an orientation such that the scanning direction of the coating nozzle liquid 5 crosses at the dicing lines D formed on the wafer W. After completion of the application, the wafer W is returned to the original orientation and thereafter the wafer W is unloaded from a coating film forming apparatus. The coating film forming apparatus stores a plurality of recipes defining coating conditions for each kind of wafer W. The coating conditions defined by the recipes include the orientation of the wafer W. The orientation of the wafer W is automatically set based on the selected recipe.

    摘要: A semiconductor device with an electrode wiring structure comprises at least one diffused region provided in a semiconductor substrate, a silicon oxide layer covering the substrate surface, a silicon nitride layer provided on the silicon oxide layer, a through-hole reaching the diffused region through the silicon oxide layer from an upper surface of the silicon nitride layer, a silicon semiconductor layer filled in the through-hole and serving as an electrode wiring layer, and an interconnection layer electrically connected to the diffused region through the silicon semiconductor layer. According to the structure, since the silicon oxide layer is covered with the silicon nitride layer, unwanted contaminations such as phosphorus, boron, etc., previously contained in the silicon oxide layer are not added to the silicon semiconductor layer during its growth process. Therefore, the electrode wiring layer of silicon semiconductor having controlled conductivity can be provided.
