    摘要: A method of etch polysilicon adjacent to a recessed STI structure feature is described. A substrate is provided with a dielectric layer thereon and a polysilicon layer on the dielectric layer. A shallow trench is formed that extends through the polysilicon and dielectric layers into the substrate. An insulating material is used to fill the trench and is then recessed in the trench below the surface of the substrate by polishing and etching steps. A conformal buffer layer is deposited which covers the polysilicon and sidewalls of the trench above the recessed insulating layer. The buffer layer is etched back to expose the insulating layer and the polysilicon is removed by a plasma etch. A spacer comprised of a portion of the buffer layer protects the substrate during the polysilicon etch to prevent unwanted trenches from being formed adjacent to the STI structure, thereby increasing the etch process window.

    摘要: A real-time and in-line process control system maintains stable plating performance in copper electrochemical plating IC devices by using a real time, on-line programmable controller. Two or more valves to direct the flow of the electrolyte from the electroplating cell back to the reservoir connect an alternative carbon-filter as well as a mirco-filter. The programmable controller controls the operation of at least two in-line valves to direct the flow of the electrolyte within the system.
