    Abstract: A resistor (14) and a resistive link (1,15) are provided in an integrated circuit structure, and a dielectric layer (30-2) is formed over the resistive link. The resistor and the resistive link are connected in parallel. The resistance of the resistor is trimmed by forming a cut entirely through the resistive link, by advancing a laser beam (3) through a trim region (4,4-1) of the resistive link in a direction at an angle in the range of approximately 0 to 60 degrees relative to a longitudinal axis of the resistive link so as to melt resistive link material. The advancing laser beam tends to sweep the melted material in the direction of beam movement. Re-solidified link debris accumulates sufficiently far apart and sufficiently far from a stub (15A) of the resistive link to prevent significant leakage current in the resistive link.

    Abstract: Electrical components for microelectronic devices and methods for forming electrical components. One particular embodiment of such a method comprises depositing an underlying layer onto a workpiece, and forming a conductive layer on the underlying layer. The method can continue by disposing a dielectric layer on the conductive layer. The underlying layer is a material that causes the dielectric layer to have a higher dielectric constant than without the underlying layer being present under the conductive layer. For example, the underlying layer can impart a structure or another property to the film stack that causes an otherwise amorphous dielectric layer to crystallize without having to undergo a separate high temperature annealing process after disposing the dielectric layer onto the conductive layer. Several examples of this method are expected to be very useful for forming dielectric layers with high dielectric constants because they avoid using a separate high temperature annealing process.

  • Patent number: 7449032
    Abstract: A surface mount capacitor (10) and method for making the same. A solid slug or pellet anode body (1) is encapsulated in a case (6) of insulating material. An anode and cathode termination pair (2, 3) are formed with surface mount mounting portions on one side of the case (6). An electrical connection (4) is made from the cathode termination (2) to a cathode on pellet (1) through the case (6). An electrical connection (7) is made between an anode associated with the pellet (1) and the anode termination (3) externally of the case (6).

  • Patent number: 7446010
    Abstract: A method is provided for forming a metal/semiconductor/metal (MSM) back-to-back Schottky diode from a silicon (Si) semiconductor. The method deposits a Si semiconductor layer between a bottom electrode and a top electrode, and forms a MSM diode having a threshold voltage, breakdown voltage, and on/off current ratio. The method is able to modify the threshold voltage, breakdown voltage, and on/off current ratio of the MSM diode in response to controlling the Si semiconductor layer thickness. Generally, both the threshold and breakdown voltage are increased in response to increasing the Si thickness. With respect to the on/off current ratio, there is an optimal thickness. The method is able to form an amorphous Si (a-Si) and polycrystalline Si (polySi) semiconductor layer using either chemical vapor deposition (CVD) or DC sputtering. The Si semiconductor can be doped with a Group V donor material, which decreases the threshold voltage and increases the breakdown voltage.

  • Patent number: 7442603
    Abstract: A process in the manufacturing of a resistor random access memory with a confined melting area for switching a phase change in the programmable resistive memory. The process initially formed a pillar comprising a substrate body, a first conductive material overlying the substrate body, a programmable resistive memory material overlying the first conductive material, a high selective material overlying the programmable resistive memory material, and a silicon nitride material overlying the high selective material. The high selective material in the pillar is isotropically etched on both sides of the high selective material to create a void on each side of the high selective material with a reduced length. A programmable resistive memory material is deposited in a confined area previously occupied by the reduced length of the poly, and the programmable resistive memory material is deposited into an area previously occupied by the silicon nitride material.
