    摘要: An instantaneous pressure reducing heating and drying apparatus for an object, such as a wafer, includes a pressure reducing chamber; a vacuum pump for reducing a pressure in the pressure reducing chamber to below atmospheric pressure; a drying chamber installed within the pressure reducing chamber for drying the object that is loaded in the drying chamber; a pressure regulating valve installed in a wall of the drying chamber, wherein when the pressure regulating valve is opened a pressure in the drying chamber is instantaneously reduced to the pressure of the pressure reducing chamber; and a heating means for heating the drying chamber. In operation, the vacuum pump reduces a pressure of the pressure reducing chamber to below atmospheric pressure, and the pressure regulating valve installed in a wall of the drying chamber opens thereby instantaneously reducing the pressure the drying chamber to the reduced pressure of the pressure reducing chamber.

    摘要: A wafer having a dielectric layer and an electrode partially protruding from the top surface of the dielectric layer is provided. The dielectric layer is etched with a chemical solution such as LAL. Prior to etching, the protruding portion of the electrode is removed or reduced to prevent any bubbles included in the chemical solution from adhering to the electrode. Thus, the chemical solution can etch the dielectric layers without being blocked by any bubbles included in a chemical solution.
