    • A method of forming a light weight, closed-back mirror. The mirror is formed as a monolithic construction by the use of chemical vapor deposition techniques. A first deposition forms sheets of the material, which are machined to the proper size to form reinforcing ribs. A sacrificial mandrel is formed with grooves to receive the ribs in their assembled positions. The upper surface of the mandrel is in proximity to the rear edges of the ribs to form a substantially continuous surface. The mandrel and ribs are then subjected to a chemical vapor deposition process which forms a first coating upon the outer face of the mandrel, forming a back plate and side wall. The mandrel is then turned over, and the base is removed by machining to expose the front edges of the ribs. This process leaves islands of mandrel material between the ribs to form a substantially continuous surface. The mandrel and ribs are then subjected to a chemical vapor deposition process. This forms a second coating upon the lower surface of the mandrel, used as the mirror face. To reduce weight, holes are drilled through the back plate, and the remaining, encapsulated, mandrel material is removed by oxidation.
    • 一种形成轻质封闭式后视镜的方法。 反射镜通过使用化学气相沉积技术形成为整体结构。 首先沉积形成材料片材,其被加工成适当的尺寸以形成加强肋。 牺牲心轴形成有凹槽以在其组装位置接收肋。 心轴的上表面靠近肋的后边缘以形成基本连续的表面。 然后将心轴和肋条进行化学气相沉积工艺,其在心轴的外表面上形成第一涂层,形成背板和侧壁。 然后将心轴翻转,并且通过机械加工去除基底以露出肋的前边缘。 该工艺在肋之间留下芯棒材料岛以形成基本连续的表面。 然后对心轴和肋进行化学气相沉积工艺。 这在心轴的下表面上形成第二涂层,用作镜面。 为了减轻重量,通过后板钻出孔,并且通过氧化除去剩余的封装的心轴材料。

    • A susceptor for rapid thermal processing for epitaxial deposition upon semiconductor wafers. The susceptor includes an outer supporting ring upon which the wafer rests. This outer ring is preferably formed of a monolithic mass of silicon carbide, and most preferably high purity .beta.-phase (face-centered cubic) silicon carbide. The wafer is supported upon a small wafer shoulder on the ring. To prevent deposition upon the rear or bottom face of the wafer, a blocker shoulder is also provided in the ring, below the wafer shoulder, and a blocker is placed upon this shoulder. The blocker is preferably formed of quartz, and simply rests upon the shoulder. In this manner the ring and blocker may expand at different rates upon the rapid temperature changes, and the blocker or ring may be replaced.
    • 用于快速热处理的基座,用于在半导体晶片上进行外延沉积。 基座包括外部支撑环,晶片搁置在该外部支撑环上。 该外环优选由碳化硅的整体块,最优选高纯度β相(面心立方)碳化硅形成。 晶片被支撑在环上的小晶片肩上。 为了防止沉积在晶片的后表面或底面上,在环中还设置有阻挡肩,在晶片肩部下方,并且阻挡器被放置在该肩部上。 阻塞剂优选由石英形成,并且仅仅靠在肩部上。 以这种方式,环和阻挡剂可以在快速温度变化时以不同的速率膨胀,并且可以更换阻滞剂或环。
