  • Etch Applied Materials

    The etch process removes selected areas from the surface of the wafer so that other materials may be deposited. “Dry” (plasma) etching is used for circuit-defining steps, while “wet” etching (using chemical baths) is used mainly to clean wafers. Dry etching is one of the most frequently used processes in semiconductor manufacturing.
