    摘要: A semiconductor device is described that operates as an improved junction field effect transistor (JFET). A bipolar transistor with a collector region, a base region, an emitter region, a first base contact, and a second base contact insulated from the first base contact, has the base region lightly doped to about a 1E16 to 5E17 atoms/cm3 doping level. A connection is provided between the emitter region and the collector region to act as a JFET gate contact for the bipolar transistor. The semiconductor device operates as an improved JFET with the first base contact being a drain contact and the second base contact being a source contact. A method for manufacture of an improved JFET on a chip containing conventional bipolar devices is also described. The improved JFET is shown being used with a write head in a disk drive system for providing electrostatic discharge protection.

    摘要: The invention, in one aspect, provides a method of manufacturing a semiconductor device. This method includes providing a semiconductor substrate and depositing a metal layer over the semiconductor substrate that has an overall thickness of about 1 micron or greater. The metal layer is formed by depositing a first portion of the thickness of the metal layer, which has a compressive or tensile stress associated therewith over the semiconductor substrate. A stress-compensating layer is deposited over the first portion, such that the stress-compensating layer imparts a stress to the first portion that is opposite to the compressive or tensile stress associated with the first portion. A second portion of the thickness of the metal layer is then deposited over the stress-compensating layer.

    摘要: A shallow trench isolation structure having a negative taper angle. A graded doped sacrificial layer is formed over a semiconductor substrate and etched to form a first trench therein having trench sidewalls that present a negative taper angle. The substrate is also etched to form a second trench therein overlying the first trench. Silicon dioxide fills both the first and the second trenches to form the shallow trench isolation structure, with the silicon dioxide in the first trench exhibiting a negative taper angle to avoid formation of polysilicon stringers during a gate polysilicon deposition.

    摘要: In a semiconductor substrate, a shallow trench isolation structure having a dielectric material disposed in voids of a trench-fill material and a method for forming the shallow trench isolation structure. The voids may be formed during a wet clean process after the dielectric material is formed in the trench. A conformal silicon nitride layer is formed over the substrate and in the voids. After removal of the silicon nitride layer, the voids are at least partially filled by the silicon nitride material.
