    摘要： A universal clock generator circuit, in accordance with the present invention, includes an oscillator unit including circuitry for providing a first clock frequency. A plurality of load blocks are included. The load blocks are selectively connectable to the oscillator such that a range of clock rates are derived from the first clock frequency by selectively connecting a number of the load blocks to the oscillator unit to provide one of a plurality of clock frequencies from a same output.

    摘要： A semiconductor structure includes a diamond-like carbon layer as a polish-stop for patterning a metal level into an inter-level dielectric substrate in a damascene process flow. The semiconductor structure includes a substrate having a dielectric layer followed by the diamond-like carbon layer on a surface thereof. The diamond-like carbon layer is used as a hard-mask for forming conductive metal features from grown substrate material that fills a plurality of openings in the substrate, therein forming a semiconductor island structure, The semiconductor structure has a planar surface at the diamond-like carbon layer and the grown substrate material, whereby the diamond-like carbon polish-stop layer allows for over-planarization of the semiconductor island structure to provide an improved planar surface having a sufficient decrease in topography.
