  • Publication number: 20070210314
    Abstract: A method for forming a semiconductor device includes providing a substrate region having a first material and a second material overlying the first material, wherein the first material has a different lattice constant from a lattice constant of the second material. The method further includes etching a first opening on a first side of a gate and etching a second opening on a second side of the gate. The method further includes creating a first in-situ p-type doped epitaxial region in the first opening and the second opening, wherein the first in-situ doped epitaxial region is created using the second material. The method further includes creating a second in-situ n-type doped expitaxial region overlying the first in-situ p-type doped epitaxial region in the first opening and the second opening, wherein the second in-situ n-type doped epitaxial region is created using the second material.

  • Publication number: 20070171700
    Abstract: An electronic device can include a static-random-access memory cell. The static-random-access memory cell can include a first transistor of a first type and a second transistor of a second type. The first transistor can have a first channel length extending along a first line, and the second transistor can have a second channel length extending along a second line. The first line and the second line can intersect at an angle having a value other than any integer multiple of 22.5°. In a particular embodiment, the first transistor can include a pull-up transistor, and the second transistor can include a pass gate or pull-down transistor. A process can be used to form semiconductor fins and conductive members, which include gate electrode portions, to achieve the electronic device including the first and second transistors.

  • Publication number: 20070102755
    Abstract: An electronic device can include a transistor structure of a first conductivity type, a field isolation region, and a layer of a first stress type overlying the field isolation region. For example, the transistor structure may be a p-channel transistor structure and the first stress type may be tensile, or the transistor structure may be an n-channel transistor structure and the first stress type may be compressive. The transistor structure can include a channel region that lies within an active region. An edge of the active region includes the interface between the channel region and the field isolation region. From a top view, the layer can include an edge the lies near the edge of the active region. The positional relationship between the edges can affect carrier mobility within the channel region of the transistor structure.

  • Publication number: 20070093043
    Abstract: A semiconductor structure includes a substrate having a memory region and a logic region. A first p-type device is formed in the memory region and a second p-type device is formed in the logic region. At least a portion of a semiconductor gate of the first p-type device has a lower p-type dopant concentration than at least a portion of a semiconductor gate of the second p-type device. The semiconductor gates of the first and second p-type devices each have a non-zero p-type dopant concentration.

  • Publication number: 20060043498
    Abstract: A method and apparatus is presented that provides performance enhancement in a semiconductor device. In one embodiment, a first current region (64, 76, 23), a channel region and a second current region (75, 33, 66) are adjacent each other. The second current region (75, 33, 66) has a content of a first element of an alloy greater than a content of the first element in the first current region (64, 76, 23), wherein the second current region (75, 33, 66) has a content of the first element greater than a content of the first element in the channel region, the alloy further comprises a second element, the first element has a first valence number, and the second element has a second valence number. Furthermore, the sum of the first valence number and the second valence number is eight.
