The present invention provides a method and composition for controlling the growth of microorganisms in aqueous systems, such as industrial process waters. The method includes the steps of adding a synergistically effective amount of a biocide, 2-bromo-2-nitrostyrene ("BNS"), and an oxidant, peracetic acid, to industrial process waters to control microorganism growth. The composition of the present invention comprises a synergistically effective amount of a biocide, 2-bromo-2-nitrostyrene, and an oxidant, peracetic acid, to control microorganism growth. The method and composition of the present invention are particularly effective in the treatment of pulp and paper water processing systems.

A method for forming a polycide layer wherein the silicide layer is blanket deposited over a polysilicon layer and selectively ion implanted through a mask to form regions of a higher resistivity than the masked regions. The implanted polycide layer is then annealed by RTA and patterned to form the conductors, gate electrodes and interconnects from the low resistivity regions and resistive components of an integrated circuit from the high resistivity regions. The capability of selecting from high and low resistive regions in a single polycide layer permits the design of resistive components with smaller areas than would be permitted if the resistive components were formed of a single low resistivity layer. This extra degree of freedom permits the designer to optimize device density and device performance without compromising either. The procedure utilizes a additional masking step utilizing a block-out mask.
