    摘要: A new method is provided to monitor and to prevent IMD oxide irregularities such as IMD oxide cracks. A monitoring pattern is inserted in the test line of the fabrication substrate to monitor the strength of the created layer of IMD oxide. Variations in the characteristics of the created layer of IMD oxide can in this manner be detected. In addition, design rules are provided that are aimed at avoiding layers of IMD oxide that have proven or are known to be particularly prone to the occurrence of IMD oxide cracks.

    摘要: Multigate transistor devices and methods of their fabrication are disclosed. In accordance with one method, a fin and a gate structure that is disposed on a plurality of surfaces of the fin are formed. In addition, at least a portion of an extension of the fin is removed to form a recessed portion that is below the gate structure, is below a channel region of the fin, and includes at least one angled indentation. Further, a terminal extension is grown in the at least one angled indentation below the channel region and along a surface of the channel region such that the terminal extension provides a stress on the channel region to enhance charge carrier mobility in the channel region.

    摘要: The specification and drawings present a new method, device and computer/software related product (e.g., a computer readable memory) are presented for realizing eDRAM strap formation in Fin FET device structures. Semiconductor on insulator (SOI) substrate comprising at least an insulator layer between a first semiconductor layer and a second semiconductor layer is provided. The (metal) strap formation is accomplished by depositing conductive layer on fins portion of the second semiconductor layer (Si) and a semiconductor material (polysilicon) in each DT capacitor extending to the second semiconductor layer. The metal strap is sealed by a nitride spacer to prevent the shorts between PWL and DT capacitors.

    摘要: FinFETS and methods for making FinFETs with a recessed stress liner. A method includes providing an SOI substrate with fins, forming a gate over the fins, forming an off-set spacer on the gate, epitaxially growing a film to merge the fins, depositing a dummy spacer around the gate, and recessing the merged epi film. Silicide is then formed on the recessed merged epi film followed by deposition of a stress liner film over the FinFET. By using a recessed merged epi process, a MOSFET with a vertical silicide (i.e. perpendicular to the substrate) can be formed. The perpendicular silicide improves spreading resistance.
