    摘要: This invention relates to a method of manufacturing a semiconductor device having elements isolated by a trench. A trench is formed to surround an element region of a silicon substrate by anisotropic etching. A nonoxide film such as a silicon nitride film is selectively formed on the upper surface of the element region. Thermal oxidation is performed using the nonoxide film as a mask to form an oxide film on the inner face of the trench and the upper surface of a field region. Thereafter, a polysilicon layer is buried in the trench, and after the surface of the polysilicon layer is flattened, a capping oxide film is formed on the upper surface of the trench. In addition, a non-oxide film is formed to have an interval between the end of the nonoxide film and the trench of 2 .mu.m or more.

    摘要: A heat-treatment apparatus includes a quartz heat-treatment tube having a vertically set axis in which a heat-treatment gas is supplied from its lower portion, and a quartz cap to be mounted on an upper opening portion of the heat-treatment tube. An opening is formed in a central portion of the cap, a quartz rod is inserted through the opening along the axis of the heat-treatment tube, and semiconductor parts to be heat-treated are held by the rod. A first exhaust duct is formed in a side surface of the heat-treatment tube at a position higher than at least the semiconductor parts held by the rod and exhausts the heat-treatment gas in the heat-treatment tube. A ring-like chamber open toward the inner surface of the cap is formed in the outer circumferential surface of the heat-treatment tube in a position close to the upper opening surface, and a second exhaust duct communicates with this chamber. The chamber communicates with the opening portion formed in the cap in the outer circumferential portion of the rod and communicates with the interior of the heat-treatment tube, thereby exhausting an external air drawn from the opening together with the heat-treatment gas in the heat-treatment tube.
