  • Patent number: 11400559
    Abstract: The polishing pad according to an embodiment adjusts the content of elements present in the polishing layer, thereby controlling the bonding strength between the polishing pad and the polishing particles and enhancing the bonding strength between the polishing particles and the semiconductor substrate (or wafer), resulting in an increase in the polishing rate. It is possible to enhance not only the mechanical properties of the polishing pad such as hardness, tensile strength, elongation, and modulus, but also the polishing rate for both a tungsten layer or an oxide layer. Accordingly, it is possible to efficiently fabricate a semiconductor device of excellent quality using the polishing pad.

  • Patent number: 11389923
    Abstract: Shortcomings associated with insufficient control of a conventional CMP-process are obviated by providing an CMP-apparatus configured to complement a constant force (to which a workpiece that is being polished is conventionally exposed) with a time-alternating force and/or means for measuring an electrical characteristic of the CMP-process. The time-alternating force is applied with the use of a system component that is electrically isolated from the workpiece and that is disposed in the carrier-chick in which the workpiece is affixed for CMP-process, while the electrical characteristic is measured with the use of a judiciously-configured reservoir in which the used fluid is collected. The use of such CMP-apparatus.
