Abstract: A system and method is disclosed for providing a deep connection to a substrate or buried layer of a semiconductor device. Three shallow trenches are etched halfway through a layer of epitaxial silicon that is located on a substrate. A second doped layer is created in the epitaxial silicon layer at the bottom of the central shallow trench. First and third doped layers are created in the epitaxial silicon layer adjacent to the central shallow trench. An oxide layer is then deposited to fill the three trenches. The second doped layer is diffused vertically down to the substrate. The first and third doped layers are diffused vertically down to the second doped layer. Lateral diffusion of the first and third doped layers is constrained by the oxide layer in the three trenches.

Abstract: A system and method is disclosed for using a differential wet etch stop technique to provide a uniform oxide layer over a metal layer in a laser trimmed fuse. A layer of boron doped oxide with a slow etch rate is placed over the metal layer. A layer of phosphorus doped oxide with a fast etch rate is placed over the boron doped oxide. The time period required for a wet etch process to etch through the phosphorus doped oxide is calculated. The wet etch process is then applied to the phosphorus doped oxide for the calculated time period. The wet etch process slows significantly when it reaches the boron doped oxide. This method forms a uniform layer of boron doped oxide over the metal layer.

Abstract: A method for preparing both main label and warning label portions for a container useful in dispensing drugs by a pharmacist in which the main label portion contains specific drug or patient information and the warning label portion contains one or more warnings specific to the drug or patient information includes the steps of providing a backing sheet having the main label portion and the warning label portion releasably adhered thereto, printing the drug or patient information on the warning label during only one printing pass, and then affixing both the main label portion and the warning label portion to a drug container.

Abstract: A system and method is disclosed for selectively increasing a wet etch rate of a large raised area portion of a semiconductor wafer with respect to a wet etch rate of a small raised area portion of the semiconductor wafer. A resist mask on the semiconductor wafer is etched to create a large via over the large raised area portion and a small via over the small raised area portion. An ion implantation beam is applied with an impact direction that enables ions to pass through the large via but does not enable ions to pass through the small via. The ions that pass through the large via increase the wet etch rate of the underlying portion of the semiconductor wafer. In one embodiment the impact direction has a tilt angle of forty five degrees and a rotation angle of forty five degrees.

Abstract: A system and method is disclosed for providing a self heating adjustable titanium disilicon (TiSi2) resistor. A triangularly shaped layer of polysilicon is placed a layer of insulation material. A layer of titanium is applied over the polysilicon and heated to form a layer of C49 type of TiSi2. A current is then applied to the small end of the triangularly shaped layer of C49 TiSi2. The current generates heat in a high resistance portion of the triangularly shaped layer of C49 TiSi2 and converts a portion of the C49 TiSi2 to C54 TiSi2. The lower resistance of the C54 TiSi2 decreases the effective resistance of the resistor. A desired value of resistance may be selected by adjusting the magnitude of the applied current.

Abstract: A system and method is disclosed for providing a variable breakdown bipolar transistor. A trench is etched in a substrate between a first area (base/emitter area) and a second area (sinker/collector area). The sinker/collector contact area and a portion of the bottom of the trench adjacent to the sinker/collector area are then heavily doped. The lateral distance between the base/emitter area and the edge of the heavily doped trench determines the breakdown voltage between the emitter and collector and between the base and collector. Heat treatment diffuses the dopant in the bottom of the trench laterally and diffuses the dopant in the sinker/collector area downward until the two areas are joined to form a unified sinker/collector structure.

Abstract: A printer blank for a computer system printer is disclosed. The blank has a contiguous pressure adhesive backed label section and may also have a larger plain paper section separated from the label section by a perforation line. The label section is comprised of a plurality of adhesive backed labels and a backing sheet, including a main label portion and at least one smaller auxiliary label. A preferred blank comprises a plurality of auxiliary labels. In use, at least one, but preferably not all, of the auxiliary labels on such a preferred blank are simultaneously removed from the backing sheet with the main label portion. Any auxiliary label(s) simultaneously removed with the main label but not printed upon are readily separated from the main label.

Abstract: A tape dispensing apparatus including a tape container having tape dispensing apertures and a plurality of slots for partitions between rolls of tape. The partitions in the slots are individually formed from portions of boxes for the tapes. The portions of the boxes are integral with the boxes with the tapes therein but have lines of demarcation from the remainders of the boxes for being torn therefrom.
