    摘要: A method for making semiconductor integrated circuits which improves and decreases fringing capacitance in semiconductor integrated circuits. An oxygenated, single-crystal silicon lamella is lightly doped, producing an excess of holes, thereby forming a semiconductor substrate. The substrate is used to fabricate semiconductor devices in the usual way, except that density may be slightly increased. After fabrication, the substrate is heated, preferably at 450.degree. C., until resistivity of the substrate has increased so that non-diffused regions of the substrate are substantially non-conductive.

    摘要: Conductivity modulation states in a first component of a power integrated circuit are dynamically isolated from a second component of the integrated circuit having at least one common active region with the first component by selective irradiation of portions of the common regions between the components. Preferably the irradiation is accomplished by masking the component portions of the body with a radiation shield and irradiating selected portions of the common active regions between the component portions with a suitable radiation source. The radiation source is preferably an electron beam of an energy level between about 1 and 3 Mev, preferably where the irradiation is carried to a dosage between 1.times.10.sup.13 and 1.times.10.sup.15 e/cm.sup.2 and most desirably between 4.times.10.sup.13 and 2.times.10.sup.14 e/cm.sup.2. New high speed bilateral thyristors, reverse switching rectifiers and reverse conducting thyristors are also provided.

    摘要: A process for substantially reducing the overlap between a gate and the source and drain regions of a field-effect transistor is disclosed. Lateral etching of a polysilicon gate provides overhangs which extend from a gate masking member. Source/drain regions are formed by ion implanting through the gate oxide layer. A small amount of dopant is implanted through the overhangs providing a low concentration of dopant in alignment with the gate. During subsequent processing, this low concentration of dopant does not substantially diffuse as do regions of higher concentration. Significant reduction in Miller capacitance is obtained along with improved punch-through characteristics.

    摘要: Low dosage phosphorus implantation regions in P-type silicon are subjected to a severe damage implant with halogen or silicon ions, preferably fluorine and chlorine. This permits anneal in a strongly oxidizing atmosphere for PN junction passivation, without concurrently inducing PN junction leakage. Oxide passivated PN junctions are formed having leakages as low as when the low dose phosphorus implants are annealed in other atmospheres, or are formed in silicon.

    摘要: A layer of substantially uniform lead monoxide is vapor deposited on a supported signal electrode of a vidicon target. The lead monoxide layer is formed on the signal electrode as a substantially homogeneous compensated intrinsic, or n type, electrically conductive material. An electrical potential is applied to the supported layer of lead monoxide to affect an electrical discharge through a continually renewed atmosphere consisting essentially of one of the inert gases, or nitrogen, whereby ion bombardment of the layer is accomplished.

    摘要: Ion implanted resistor formed in a body of crystalline semiconductor material of a first conductivity type and a known bulk resistivity with at least one region of implanted ions in the body having a conductivity opposite that of the body. The resistance changes no more than 3% from the room temperature value between - 50* and 125* C. Between 0* and 70* C., the change is only 0.3%. In the method, ion implanted resistors having the desired sheet resistivity are formed by varying the implantation energy and/or the thickness of a stopping layer. In addition, the resistor is annealed at a temperature ranging from 550* C. to 650* C.

    摘要: A method is described for forming buried layers by ion implantation which includes removal of the damaged region in the semiconductor crystal resulting from such implants. Impurity ions are implanted near the surface of a silicon substrate. The substrate is then heated in an oxidizing ambient for a sufficient length of time to allow the impurities to diffuse further into the crystal while an oxide layer grows on the surface consuming the damaged region. The oxide is removed leaving the impurities in defect-free material upon which may be grown an epitaxial layer.

    摘要: The production sequence of the UHF transistors includes at least one ion implantation step for doping the emitter, which takes place after doping of the base, through an emitter window etched from a thin oxide layer closing the base window previously etched from a thick oxide layer. This ion implantation is followed by an anneal in neutral atmosphere while the emitter window remains open, at a temperature lower than 1000*C in the case of silicon. The base is doped either by diffusion or ion implantation. Two further ion implantations are used to degenerate the base contact area and to reduce transversal base resistance.
