    摘要: An exemplary structure for a gate structure of a field effect transistor comprises a gate electrode; a gate insulator under the gate electrode having footing regions on opposing sides of the gate electrode; and a sealing layer on sidewalls of the gate structure, wherein a thickness of lower portion of the sealing layer overlying the footing regions is less than a thickness of upper portion of the sealing layer on sidewalls of the gate electrode, whereby the field effect transistor made has almost no recess in the substrate surface.

    摘要: Disclosed is a seasoning method for an etch chamber for improving the passing rate, comprising the steps of: introducing a wafer or plural control wafers into the etch chamber; introducing reacting gases into the etch chamber; applying power to top and bottom electrodes of the etch chamber to plasmarize the reacting gases; and adjusting the gate valve of the etch chamber to 90 to 100% of the fully open position, thereby reducing the amount of by-products and eliminating the factors for reducing the passing rate. The seasoning method of this invention is based on a low pressure, high flow-rate sluicing mechanism, where the atmospheric flow and high vacuuming ability would remove the maximum amount of polymer particles and flaking from the etch chamber.
