Abstract:
The continuous processing of semiconductor wafers transported through a reactor system having a series of reaction zones permitting separate process functions, with zone isolation achieved through the use of dynamically sealed vapor-purged isolation chambers. An in-line, verticaL arrangement of gas inlets and outlets and planar work supports effect a laminar flow of gaseous materials.
Abstract:
A planar integrated semiconductor circuit having common emitter transistor elements isolated from each other and from other transistors by the emitter regions which form a PN or rectifying junction with the body of the semiconductor member in which the integrated circuit is formed. In a semiconductor member or body of one type conductivity, a plurality of emitter regions of opposite type conductivity extend from one planar surface of the body. One or more of the emitter regions each have a plurality of discrete base regions of the one type conductivity extending from said planar surface fully enclosed within the emitter region. Each of the base regions in turn has at least one collector region enclosed within it at the planar surface. The emitter region has a higher majority carrier concentration than the majority carrier concentration within its enclosed base regions. The rectifying junction formed by the opposite conductivity emitter region with the one type conductivity semiconductor body serves to isolate the emitter regions from each other.

Abstract:
A semiconductor device and a method for fabricating the same which is composed of a monocrystalline semiconductor body having a surface crystallographic orientation substantially parallel to a plane and having a PN junction formed in the body. The body has an insulator coating, such as silicon dioxide, over the PN junction. The surface state density at the semiconductorinsulator interface is very low. This low density is believed to be a reason for the increased beta in the oriented material semiconductor device. Further, the device has a low defect density and few dopant precipitate sites even at high dopant levels. A monolithic integrated circuit structure composed of the monocrystalline semiconductor substrate having a surface crystallographic orientation substantially parallel to a plane with a plurality of semiconductor devices within the substrate is described. The devices are isolated from one another by PN junctions. The tolerance in a given isolated device, between the PN junction and the nearest region having a different conductivity is less than approximately 0.3 mils. This very close spacing allows substantially greater compactness of semiconductor devices within a monocrystalline semiconductor body than has ever been previously accomplished.
Abstract:
A METHOD FOR FORMING ALUMINUM OHMIC CONTACTS AND CONDUCTIVE CONNECTORS ON SEMICONDUCTOR DEVICES HAVING SILICON DIOXIDE PASSIVATING MASKS COVERING PORTIONS OF A SEMICONDUCTOR SUBSTRATE. THE ALUMINUM CONTACTS AND CONNECTORS ARE FORMED BY THE DISPROPORTIONATION OF ALUMINUM MONO-HALIDE VAPOR IN THE PRESENCE OF THE SILICON DIOXIDE
MASKED SUBSTRATE. THE ALUMINUM FORMED BY THE DISPROPORTIONATION IS DEPOSITED AS A LAYER OVER THE MASKED SUBSTRATE. THEN, PORTIONS OF THE ALUMINUM LAYER ARE SELECTIVELY REMOVED TO LEAVE A PATTERN OHMIC CONTACTS AND CONDUCTIVE CONNECTORS.
