    • 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.
    • 本发明涉及一种制造半导体器件的方法,该半导体器件具有通过沟槽隔离的元件。 通过各向异性蚀刻形成沟槽以包围硅衬底的元件区域。 在元件区域的上表面上选择性地形成诸如氮化硅膜的非氧化物膜。 使用非氧化物膜作为掩模进行热氧化,以在沟槽的内表面和场区的上表面上形成氧化膜。 此后,多晶硅层被埋在沟槽中,并且在多晶硅层的表面变平时,在沟槽的上表面上形成覆盖氧化物膜。 此外,形成非氧化物膜,其在非氧化物膜的端部和沟槽之间具有2μm以上的间隔。

    • 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.
    • 热处理装置包括:石英热处理管,其具有从其下部供给热处理气体的竖直设定轴;以及石英盖,安装在所述热处理管的上开口部。 在盖的中央部形成有开口部,沿着热处理管的轴线将石英棒贯穿该开口部,通过该杆保持被热处理的半导体部件。 第一排气管在热处理管的侧表面形成在比由杆保持的至少半导体部分高的位置,并排出热处理管中的热处理气体。 在靠近上开口表面的位置,在热处理管的外周面上形成有朝向盖的内表面开口的环状室,第二排气管与该室连通。 该室与杆的外周部形成的开口部连通,与热处理管的内部连通,从而将与开口一起从外部吸入的外部空气与热处理气体一起排出 处理管。
