    Abstract: SEMICONDUCTOR PLASMA OXIDATION Uniform growth of oxide at low temperature can be performed in a plasma environment by positioning the substrates on which the oxide is to grow outside of the plasma area and independently supplying heat to the substrates in the presence of controlled oxygen pressure.

    Abstract: IMPROVED DSDT TARGET AND METHOD FOR FABRICATING THE SAME A process for the fabrication of a deformographic storage display tube (DSDT) target in which a wafer of silicon or other etchable material is used (1) as a temporary support during the generation of the active region of the target and (2) as a supporting structure for the completed target. The DSDT target structure comprises a reflection layer on a dielectric layer supported in turn on a silicon or other etchable material wafer, the wafer being etched off at its back side to expose the dielectric layer while providing an outer frame support structure made of the wafer around the edge, with the dielectric layer being etched to form pillars of the dielectric on the backside of the reflection layer, whereby the dielectric pillars enable a deformation action to occur in the region between the pillars. An inner frame support structure comprised of a similarly etched wafer, a dielectric layer and a secondary electron emission layer is fitted against the bottoms of the pillars and bonded to the outer frame support structure, thereby forming the completed target.

    Abstract: In an ink jet printing system, a single nozzle or an array of nozzles are etched in a semiconductor material such as silicon. Each nozzle has polygonal or N-sided entrance and exit apertures of different cross-sectional area. Preferably, the nozzle is in the shape of a truncated pyramid with the entrance and exit apertures being substantially square in cross-section. The corners of the apertures and wall interfaces may be rounded to reduce stress concentrations.

    Abstract: 1,143,255. Vapour polishing of IIIB-VB compounds. INTERNATIONAL BUSINESS MACHINES CORP. 2 Nov., 1966 [17 Nov., 1965], No. 49045/66. Heading C1A. The surface of a substrate of a III B -V B compound is polished by exposing it at elevated temperatures to a flowing gas stream containing a hydrogen halide and the Group V B element at a partial pressure sufficient to prevent dissociation of the compound. The substrate is then suitable for epitaxial deposition without removal from the site. The compound may be an arsenide, antimonide, or phosphide of Ga or In. Preferably GaAs is exposed to an atmosphere of H 2 +HI+As at a p.p. of 15-300 Torr, at a temperature from 1000‹ C. to the m.pt. of GaAs, e.g. 1100-1200‹ C. HI may be supplied from a tank, or generated by passing H 2 over heated I 2 and through a heated Pt bed. The mixture of HI and H 2 is then passed over a heated source of solid As. Alternatively, a decomposable compound of the Group V B element may be used, e.g. AsH 3 , SbH 3 , or PH 3 . The substrate may previously have been mechanically or chemically polished. Its surface may be oriented in the (111), (211), (100) or (110) plane.
