    摘要: A multiplicity of thin layers are applied on top of each other having alternately comparatively high concentrations of charge carriers and no doping. The thickness and the concentration of charge carriers of the individual layers being are proportioned in such a manner that the desired low concentration of charge carriers is yielded by averaging the multiplicity of layers.

    摘要: A buried stripe semiconductor light emitting device and a method for producing the device in which the buried stripe functions as an internal resonator, and the device has window regions interposed between the resonator and facets on the external surface of the device. A first phase crystal growth is conducted in which a first cladding layer is grown on a doped substrate. Thereafter, a doped stripe of impurities is introduced into the first cladding layer in electrical contact with the doped substrate. The doped stripe extends longitudinally but terminates short of the facets so that later out-diffusion from the doped stripe will form the window regions. A second phase crystal growth is then conducted which buries the doped stripe internal to the semiconductor, i.e., not projecting through any external surface. The second phase crystal growth comprises an active layer, a second cladding layer and a contact layer successively grown on the first cladding layer. Impurities from the buried doped stripe are out-diffused into the active layer to the boundary between the active layer and the seocnd cladding layer to form the resonator, leaving windows interposed between the resonator ends and the facets.

    摘要: A thin film bilayer composite source comprises a deposited impurity source layer, e.g. Si or Sb, heavily doped with a diffusion enabling agent, e.g. As, and capped with a passivating layer, e.g. Si.sub.3 N.sub.4, SiO.sub.2, AlN or SiO.sub.x N.sub.y. In a preferred embodiment, a thin film bilayer composite source comprises a Si layer on the surface of said structure vapor deposited at a temperature in excess of 500.degree. C. in the presence of a source of As to hevily dope the layer in the range of 5%-20% atomic weight and a thin cap layer of Si.sub.3 N.sub.4 deposited on the Si layer at a temperature in excess of 500.degree. C. having a thickness only sufficient to prevent the outdiffusion of Ga and As, which thickness may be about 400 .ANG.-700 .ANG.. An important aspect of the employment of this bilayer composite source as a diffusion source for III-V structures is that the composite source is initially deposited at high temperatures, above 500.degree.0 C., i.e., at temperatures that are into the range of annealing temperature, e.g. about 500.degree.-900.degree. C., preferably 700.degree.-850.degree. C., so that cracking due to thermal strain or compressive stress will not occur on subsequent high temperature annealing thereby providing reproducible, uniform impurity diffusion into III-V structures. A particular application of bilayer composite source is in impurity induced disordering (IID).

    摘要: A semiconductor read/write memory comprised of an array of cells, each having a single active element that is a IGFET device formed in a recess with one source or drain region located directly above and its other source or drain region located within a buried storage capacitor. The gate of each device is connected to an address line in the array, and transverse diffused bit lines interconnect the drains of the devices in aligned and spaced apart cells. Voltage applied via an address line activates a gate to charge its buried capacitor and store a signal when its connected bit line is also activated. Readout of stored charges is controlled by the address line through the connected bit line in the conventional manner. A memory device with an array of such single element cells can be fabricated by forming an array of N-type buried layer diffusions in a P substrate, depositing an epitaxial layer of lightly doped P material that extends above the buried layer diffusions, forming a relatively thin diffusion of N material spaced directly above the buried layer, forming a recess that passes through the thin N layer and the epitaxial layer into the thicker buried N layer, and thereafter forming a gate within the recess.

    摘要: In the fabrication of integrated circuits, a method is provided for forming dielectrically isolated regions in the silicon substrate comprising selectively etching recesses in a silicon substrate and thermally oxidizing the recessed portions of the silicon substrate to form regions of recessed silicon dioxide extending into the substrate. Then, a blanket introduction of impurities of opposite-type conductivity is made into the portions of the substrate remaining unoxidized, after which a layer of silicon of said opposite-type conductivity is epitaxially deposited on the substrate surface. Next, utilizing appropriate silicon nitride masking, recesses are etched into the silicon epitaxial layer in registration with the now buried regions of recessed silicon dioxide in the substrate. Then, the recessed portions of the silicon epitaxial layer are thermally oxidized to the extent sufficient to form regions of recessed silicon dioxide extending through said epitaxial layer into registered contact respectively with the regions of recessed silicon dioxide formed in the substrate.

    摘要: This relates to a process for manufacturing monolithic integrated circuits comprising at least one pair of complementary bipolar planar transistors. The pair of transistors, having two buried layers and two superimposed epitaxially deposited layers upon a semiconductor substrate body, are manufactured by deposition of an epitaxial layer having a thickness wherein the base zone of the pnp-transistor remains and is surrounded by a p-conducting zone which is diffused during the diffusion of the base zone of the npn-transistor and a portion of an insulating zone.
