    摘要: In one embodiment, a second metal line embedded in a second dielectric layer overlies a first metal line embedded in a first dielectric layer. A portion of the second dielectric layer overlying the first metal line is recessed employing a photoresist and the second metal line as an etch mask. A doped semiconductor spacer is formed within the recess to provide a resistive link between the first metal line and the second metal line. In another embodiment, a first metal line and a second metal line are embedded in a dielectric layer. An area of the dielectric layer laterally abutting the first and second metal lines is recessed employing a photoresist and the first and second metal lines as an etch mask. A doped semiconductor spacer is formed on sidewalls of the first and second metal lines, providing a resistive link between the first and second metal lines.

    摘要: 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.

    摘要: 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.
