    摘要: A sputtering apparatus for coating a substrate comprising a first electrode for supporting a target material and a second electrode for supporting a substrate, upon which the coating is deposited. A source of RF power is connected to impose an RF voltage across the electrodes to produce a glow discharge in the space between the electrodes, and shutter means is provided in the space between the electrodes. The shutter means has means for blocking a substantial part of the sputtered atoms from the target electrode glow discharge traveling at or near normal incidence and at least one opening shaped to permit a substantial part of the sputtered atoms from the target electrode traveling at an oblique angle to impinge upon the substrate to produce a thin film coating of the target material.

    摘要: Bei einem Verfahren zum Herstellen von bipolaren Transistoren durch Ionenimplantation wird insbesondere die Basiszone (32) in eine auf ein Halbleitersubstrat (10) mit Subkollektor (14) epitaktisch aufgewachsene, die Kollektorzone bildende Halbleiterschicht (18) durch eine endgültig auf der Halbleiterschicht verbleibende, eine gleichmäßige Dicke aufweisende Siliciumdioxidschicht (20) hindurch implantiert. Anschließend werden Fenster (37, 36, 35) für den Emitterkontakt, den Basiskontakt und den Kollektorkontakt in der Siliciumdioxidschicht (20) geöffnet. Die Emitterzone (42) wird dann selektiv durch das Fenster (37) für den Emitterkontakt implantiert. Abschließend wird die die Kontakte und Verbindungsleitungen bildende Metallisierung auf die Siliciumdioxidschicht (20) aufgebracht.
    Dieses Verfahren gewährleistet trotz direkter Implantation der Emitterzone eine gleichmäßige Dicke der die abschließende Metallisierung tragenden Isolierschicht, was zu gleichmäßigen und abschätzbaren Kapazitäten führt.
