  • Patent number: 9842895
    Abstract: An integrated circuit contains a thin film resistor in which a body of the thin film resistor is disposed over a lower dielectric layer in a system of interconnects in the integrated circuit. Heads of the thin film resistor are disposed over electrodes which are interconnect elements in the lower dielectric layer, which provide electrical connections to a bottom surface of the thin film resistor. Top surfaces of the electrodes are substantially coplanar with a top surface of the lower dielectric layer. A top surface of the thin film resistor is free of electrical connections. An upper dielectric layer is disposed over the thin film resistor.

  • Patent number: 7422968
    Abstract: The present invention provides a method for manufacturing a semiconductor device, and a method for manufacturing an integrated circuit including the semiconductor devices. The method for manufacturing a semiconductor device (100) , among other steps, includes forming a gate structure (120) over a substrate (110) and forming source/drain regions (190) in the substrate (110) proximate the gate structure (120). The method further includes subjecting the gate structure (120) and substrate (110) to a dry etch process and placing fluorine in the source/drain regions to form fluorinated source/drains (320) subsequent to subjecting the gate structure (120) and substrate (110) to the dry etch process. Thereafter, the method includes forming metal silicide regions (510, 520) in the gate structure (120) and the fluorinated source/drains (320).

  • Patent number: 7397046
    Abstract: Methods (300, 400) are described for calibrating the implantation angle of an ion implanter utilized in the manufacture of semiconductor products. One method (300) includes implanting (330) phosphorous ions into a pilot wafer held by a wafer platen held at a starting implantation angle in the ion implanter. The phosphorous implantation into a p-doped substrate of the pilot or blank wafer, for example, forms a semiconductive sheet. The method (300) then includes changing the implantation angle (340), and implanting another wafer (330) with phosphorous ions. The angle changing (340) and implanting (330) of other wafers continues in this manner until all wafers or angles are implanted (350) as desired. The phosphorous implanted wafers are then measured (360) with a four-point probe, for example, to obtain the sheet resistance of all the implanted wafers.
