  • Patent number: 10147659
    Abstract: Disclosed is a method of manufacturing integrated circuit (IC) chips, which includes forming routing structure(s) that facilitate process limiting yield (PLY) testing of test devices. A routing structure includes an array of link-up regions and a set of metal pads surrounding that array. Each link-up region includes two sections, each having two nodes electrically connected to the terminals of a corresponding two-terminal test device. During PLY testing with a probe card, electrical connections between the test devices and the metal pads through the link-up regions allow each test device to be tested individually. Optionally, additional routing structures with the same footprint are formed down the line and stacked one above the other. These additional routing structures are used for PLY testing with the same probe card. Optionally, dummy pads are formed between stacked routing structures to improve robustness. Also disclosed is a semiconductor structure formed according to this method.

  • Patent number: 8642420
    Abstract: A method of fabricating a semiconductor device structure begins by forming a layer of oxide material overlying a first gate structure having a first silicon nitride cap and overlying a second gate structure having a second silicon nitride cap. The first gate structure corresponds to a p-type transistor to be fabricated, and the second gate structure corresponds to an n-type transistor to be fabricated. The method continues by performing a tilted ion implantation procedure to implant ions of an impurity species in a channel region of semiconductor material underlying the first gate structure, during which an ion implantation mask protects the second gate structure. Thereafter, the ion implantation mask and the layer of oxide material are removed, and regions of epitaxial semiconductor material are formed corresponding to source and drain regions for the first gate structure. Thereafter, the first silicon nitride cap and the second silicon nitride cap are removed.

  • Patent number: 8536019
    Abstract: Apparatus and related fabrication methods are provided for semiconductor device structures having encapsulated isolation regions. An exemplary method for fabricating a semiconductor device structure involves the steps of forming an isolation region of a first dielectric material in the semiconductor substrate adjacent to a first region of the semiconductor material, forming a first layer of a second dielectric material overlying the isolation region and the first region, and removing the second dielectric material overlying the first region leaving portions of the second dielectric material overlying the isolation region intact. The isolation region is recessed relative to the first region, and the second dielectric material is more resistant to an etchant than the first dielectric material.

  • Patent number: 8524566
    Abstract: Embodiments of a method for fabricating an integrated circuit are provided. In one embodiment, the method includes producing a partially-completed semiconductor device including a substrate, source/drain (S/D) regions, a channel region between the S/D regions, and a gate stack over the channel region. At least one raised electrically-conductive structure is formed over at least one of the S/D regions and separated from the gate stack by a lateral gap. The raised electrically-conductive structure is then back-etched to increase the width of the lateral gap and reduce the parasitic fringing capacitance between the raised electrically-conductive structure and the gate stack during operation of the completed semiconductor device.
