    摘要: Chemical vapor deposition on a semiconductor wafer is obtained in a plasma reactor having a plurality of lamps for radiantly heating the wafer. Calibrated temperature sensing means remote from the wafer is used to control the heating of the wafer. Gases are supplied by way of a plurality of tubes extending radially inwardly from the sides of the chamber. A baffle is provided to form an antechamber which aids in the uniformity of the deposition. The plasma is ignited for less than the whole deposition cycle for deposition of tungsten disilicide.

    摘要: An improved spacer means for separating and inhibiting the shorting together of conductive plates in an RF plasma reactor used in Plasma Enhanced Chemical Vapor Deposition (PECVD) processing of semiconductor devices. The improved spacer means inhibits the accumulation of conductive films on the surface of the separating means by substantially precluding the plasma field, and hence, inhibiting depositions in areas where recessed grooves are in the surface of the separating means. Accordingly, a direct electrical path on the spacer means between the multiple conductive plates of the RF plasma reactor is inhibited. As a result, the reactors can run for longer periods of time and deposit greater thicknesses of conductive films without the conductive plates shorting together causing shutdown of the process.

    摘要: High-strength fiber is prepared by coating a small grain, small diameter polycrystalline refractory oxide fiber with a specified amount of a glass-forming oxide or its precursor, and heating the coated fiber at a temperature sufficient to decompose the precursor to the oxide and/or to vitrify the oxide coating into an adherent, optically uniform, thin layer. The coating significantly increases the tensile strength of the fiber, while the fiber retains a substantial percentage of its original modulus. The fibers are especially suitable for reinforcement uses.

    摘要: A powdery mixture of cobalt hydroxide, aluminium oxide, and oxides which absorb substantially no visible light, preferably silicon dioxide, is vacuum evaporated in an oxidizing atmosphere and deposited on a base material and subsequently heat treating at approximately 300*C. The coating of the base material thereby obtained is a hard, well adherent, pure blue colored and transparent film. The proportions of the principal components of the primary mixture used for evaporation are 30 to 40 percent of cobalt hydroxide and 5 to 15 percent of aluminium oxide, the refractive index of the whole mixture is approximately equal to the refractive index of the base material and the thickness of the film produced is approximately 1/1000 mm.
