Abstract:
A method for depositing an amorphous fluorinated carbon (a-F:C) film on an integrated circuit (IC) wafer substrate, the method comprising the steps of:providing a silicon wafer having top and bottom surfaces;applying a tensile stress to the top surface of the wafer by forming a first radius curve in the wafer such that the bottom of the wafer is concavedepositing the layer of a-F:C film on the top surface of the wafer;releasing the tensile stress applied to the top surface of the wafer; andin response to releasing the tensile stress in the preceding step, applying a compressive stress to the a-F:C film, whereby the compressive stress on the a-F:C film increases the thermal stability of the a-F:C film.
