  • Patent number: 7655984
    Abstract: A semiconductor device using a CESL (contact etch stop layer) to induce strain in, for example, a CMOS transistor channel, and a method for fabricating such a device. A stress-producing CESL, tensile in an n-channel device and compressive in a p-channel device, is formed over the device gate structure as a discontinuous layer. This may be done, for example, by depositing an appropriate CESL, then forming an ILD layer, and simultaneously reducing the ILD layer and the CESL to a desired level. The discontinuity preferably exposes the gate electrode, or the metal contact region formed on it, if present. The upper boundary of the CESL may be further reduced, however, to position it below the upper boundary of the gate electrode.

  • Patent number: 7061117
    Abstract: A bump layout on the active region of a driver IC for increasing overall bump count. The layout fits IC packages that have a narrow and long body profile. Bumps are positioned close to the long side and central regions of the active region so that low marking pressure on the shorter sides of the package during chip-glass bondage is avoided. Dummy bumps may also be positioned close to the shorter sides of the package so that pressure distribution is optimized during chip-glass bondage.
