Abstract:

Device structure for active devices fabricated in a semiconductor-on-insulator (SOI) substrate and design structures for a radiofrequency integrated circuit. The device structure includes a first isolation region in the semiconductor layer that extends from a top surface of a semiconductor layer to a first depth, a second isolation region in the semiconductor layer that extends from the top surface of the semiconductor layer to a second depth greater than the first depth, and a first doped region in the semiconductor layer. The first doped region is disposed vertically between the first isolation region and an insulating layer disposed between the semiconductor layer and a handle wafer of the SOI substrate. The device structure may be included in a design structure embodied in a machine readable medium for designing, manufacturing, or testing an integrated circuit.

Abstract:

A complementary metal-oxide-semiconductor (CMOS) optical sensor structure includes a pixel containing a charge collection well of a same semiconductor material as a semiconductor layer in a semiconductor substrate and at least another pixel containing another charge collection well of a different semiconductor material than the material of the semiconductor layer. The charge collections wells have different band gaps, and consequently, generate charge carriers in response to light having different wavelengths. The CMOS sensor structure thus includes at least two pixels responding to light of different wavelengths, enabling wavelength-sensitive, or color-sensitive, capture of an optical data.

Abstract:

In one embodiment, a back-end-of-line (BEOL) resistive structure comprises a second metal line embedded in a second dielectric layer and overlying a first metal line embedded in a first dielectric layer. A doped semiconductor spacer or plug laterally abutting sidewalls of the second metal line and vertically abutting a top surface of the first metal line provides a resistive link between the first and second metal lines. In another embodiment, another BEOL resistive structure comprises a first metal line and a second metal line are embedded in a dielectric layer. A doped semiconductor spacer or plug laterally abutting the sidewalls of the first and second metal lines provides a resistive link between the first and second metal lines.
