Abstract: An improved method for forming complementary wells in a substrate is disclosed. A polysilicon layer is applied to the substrate, and the polysilicon layer is doped. An oxidation barrier layer is applied over the doped polysilicon layer. A portion of the doped polysilicon and oxidation layers are removed to expose a well region of one conductivity type in the substrate, and the well is then implanted in the exposed region. The surface of the well, and the polysilicon layer proximate the well beneath the oxidation barrier layer, are then steam oxidized until the lateral desired oxide penetration into the polysilicon layer beneath the oxidation barrier layer has been reached. This forms an oxide masking layer covering and extending beyond the formed well. The remaining oxide barrier layer is then removed to expose a well region of the other conductivity type. This second well region is spaced from the well region already formed by the extended oxide masking layer. The second well is then implanted.

Abstract: The surfaces of cylinders or fabrics moving in the press or drying section of a paper machine induce layers of air along with them, which layers of air produce positive and negative pressures at the pits or nips defined by the fabrics or web and the surface of the cylinder. The positive and negative pressures are detrimental to the mutual support contact between the web and the fabric. A method for eliminating the detrimental positive and negative pressures affects the pressure levels at the nips by blowing air in directions opposite to the direction of travel of the web or fabric passing close to a blowing device, and possibly also opposite to the direction of travel of the cylinder surface. As a result of the blowing of air, air is ejected from the pressurized nips or from spaces placed facing the nips of negative pressure on the opposite side of the running of the web and the fabric. Apparatus for carrying out the method includes a blow box placed in connection with the nip.
