    摘要: A method is provided for improving the adhesion between a photoresist layer and a dielectric, and an integrated circuit formed according to the same. A conformal dielectric layer is formed over the integrated circuit. An interlevel dielectric layer is formed over the conformal dielectric layer. The interlevel dielectric layer is doped such that the doping concentration allows the layer to reflow while partially inhibiting the adhesion of the doped layer to photoresist at an upper surface of the doped layer. An undoped dielectric layer is formed over the doped dielectric layer. A photoresist layer is formed and patterned over the undoped dielectric layer which adheres to the undoped dielectric layer. The undoped dielectric, the interlevel dielectric and the conformal dielectric layers are etched to form an opening exposing a portion of an underlying conductive region.
