  • Patent number: 8519445
    Abstract: The present invention provides a method of inducing stress in a semiconductor device substrate by applying an ion implantation to a gate region before a source/drain annealing process. The source/drain region may then be annealed along with the gate which will cause the gate to expand in certain areas due to said ion implantation. As a result, stress caused by said expansion of the gate is transferred to the channel region in the semiconductor substrate.

  • Patent number: 7901988
    Abstract: A method for forming a package-on-package structure is disclosed. The method comprises the step of providing a first semiconductor package. The first semiconductor package has at least one encapsulation layer formed on at least one side of the first semiconductor package. The method also involves the step of securing the first semiconductor package to a surface. The surface is adapted for receiving the first semiconductor package. The method further involves the step of reducing the thickness of the at least one encapsulation layer to a predetermined thickness. The at least one encapsulation layer having a portion distal the surface removed. More specifically, the thickness of the at least one encapsulation layer is reduced for providing a predetermined clearance from a second semiconductor package attachable to the first semiconductor package.

  • Patent number: 7879673
    Abstract: A method for forming a semiconductor device is presented. The method includes providing a substrate prepared with first and second regions with a first device layer. A second device layer including nanocrystals is also formed. A cover layer is provided over the second device layer. The cover layer is patterned to expose portions of the second device layer in the first and second regions. The exposed portions of the second device layer in the first and second regions are processed to form modified portions. The processing of the exposed portions at least reduces the nanocrystals to a diameter below a threshold diameter in the modified portions. The modified portions are removed.

  • Publication number: 20090315115
    Abstract: A method (and semiconductor device) of fabricating a semiconductor device provides a shallow trench isolation (STI) structure or region by implanting ions in the STI region. After implantation, the region (of substrate material and ions of a different element) is thermally annealed producing a dielectric material operable for isolating two adjacent field-effect transistors (FET). This eliminates the conventional steps of removing substrate material to form the trench and refilling the trench with dielectric material. Implantation of nitrogen ions into an STI region adjacent a p-type FET applies a compressive stress to the transistor channel region to enhance transistor performance. Implantation of oxygen ions into an STI region adjacent an n-type FET applies a tensile stress to the transistor channel region to enhance transistor performance.

  • Patent number: 6962850
    Abstract: Devices with embedded silicon or germanium nanocrystals, fabricated using ion implantation, exhibit superior data-retention characteristics relative to conventional floating-gate devices. However, the prior art use of ion implantation for their manufacture introduces several problems. These have been overcome by initial use of rapid thermal oxidation to grow a high quality layer of thin tunnel oxide. Chemical vapor deposition is then used to deposit a germanium doped oxide layer. A capping oxide is then deposited following which the structure is rapid thermally annealed to synthesize the germanium nanocrystals.
