    Abstract: A tunneling device, or array of such devices, having at least one electrode which is a single crystal. Tunnel devices having two or more electrodes are shown, as are thin film Josephson devices having two single crystal electrodes. The electrodes of any device can be of the same or different material, and the crystallographic orientations of these electrodes can be the same or different. Although the tunnel barrier is usually an insulator, it can be other materials, or even a vacuum. In a particular embodiment, the barrier is an epitaxial layer. Both in-line and crossed-stripe geometries are used.

    Abstract: A SPUTTERING PROCESS FOR DEPOSITING THIN, SINGLE CRYSTAL FILMS HAVING BULK PROPERTIES. THE PROCESS IS CHARACTERIZED BY AN EXTREMELY LOW PRE-SPUTTERING TIME, A SUBSTRATE BIAS OF AT LEAST APPROXIMATELY -30 VOLTS, AND LOW DEPOSITION TEMPERATURES. BOTH RF AND DC SPUTTERING ARE USED. IMPROVIDED THIN FILMS HAVING BULK PROPERTIES ARE PRODUCED. SAID THIN FILMS IN PARTICULAR BEING SUPERCONDUCTING MATERIALS, SUCH AS NIOBIUM. THE FILMS HAVE EXCELLENT CHEMICAL PURITY AND LOW DEFECT DENSITY, AND ARE SINGLE CRYSTALS.

    Abstract: A mask for the manufacture of semiconductor and various small components. Rare earth orthofertites, such as GdFeO3, as well as YFeO3, and LaFeO3 comprises the masking material. Rare earth combinations, such as (Gd, Eu) 1FeO3, can also be used for the masking material. This masking material is harder than the components being manufactured and is opaque to the wavelength used in photoresist techniques while being transparent to visible wavelengths over broad thickness ranges. The mask can comprise a patterned layer on a substrate or patterned bulk crystals having regions of different thickness. Substrates such as soda-lime glass, sapphire, quartz, etc. are suitable. The masking material can be deposited as large area films having good uniformity and good optical properties. The material is readily etched but is not attacked by materials used in photoresist processing. Its reflectivity is very low, thereby providing easy alignment and good image defination during use.

    Abstract: 1,173,939. Semi-conductor devices. INTERNATIONAL BUSINESS MACHINES CORP. 5 Oct., 1967 [13 Jan., 1967], No. 45427/67. Heading H1K. [Also in Division C7] A II-V, III-V and II-VI semi-conductor compound formed by a metal selected from Zn, Cd, Hg, Al, Ga, In and an element selected from P, As, Sb, S, Se, Te are prepared by cathodic deposition from a fused salt solution including ions of the chosen metal and element, the applied potential being sufficient to cause simultaneous deposition of the metal and element to form the desired compound. Preferably the constituent which is deposited in excess of its stoichiometric ratio in the compound is volatile at the temperature of the fused salt bath and is one of the Group V or Group VI elements. Typically the semi-conductor compound has the zinc blende structure and if desired it may be epitaxially deposited on a cathode formed by a single crystal of silicon. As described the fused bath includes alkali metal halides as diluent. The cell may comprise a tantalum crucible or quartz coated with graphite and serves also as anode while a graphite rod may serve as cathode. Germanium may also be used as a cathode. An inert cell atmosphere-argon, helium or nitrogen-is provided. The bath may also include compounds of dopants for the semiconductor which are codeposited with it. Examples are given of depositing crystals of GaP from baths containing Ga 2 O 3 and NaPO 3 ; A1P from baths containing Al 2 O 3 and NaPO 3 ; 8. of growing epitaxially on a Si crystal ZnSe from a bath containing ZnCl 2 and SeCl 4 . GaP doped with Zn is produced from a bath consisting of NaF, NaPO 3 , Ga 2 O 3 and ZnO and is deposited on a crystal of Si. Similarly by including also Na 2 SeO 4 in the bath, a photoluminescent GaP doped with both Zn and Se is obtained. By depositing first P-type GaP doped with Zn and then coating this with N-type GaP doped with Se, a PN junction is formed suitable for an electroluminescent diode which emits red light on the passage of current.
