Silane compositions having an aromatic functionality and a ethylenically functionality and comprising a latent acid catalyst are deposited in two or more layers on a substrate. Each layer differs in light absorption properties from an adjacent layer. Some layers may have different curing mechanisms. Such a method is useful in forming antireflective coatings.

Organosilicate resin formulation for use in microelectronic devices

This invention relates to a method of dual damascene integration for manufacture of integrating circuits using three top hard mask layers having alternating etch selectivity characteristics.

Tri-layer masking architecture for patterning dual damascene interconnects

The invention comprises adding bromide to a cooling water system containing corrosion and scale control treatment chemicals at elevated concentrations (40 ppm or greater). A fraction of the recirculating water is drawn off in a side stream and ozonated. Ozone oxidizes bromide to bromine which then serves as a biocide. The bromide levels are chosen such that the ozone/bromide reaction is preferred over the ozone/treatment chemicals reaction. Thus, the addition of bromide at elevated concentrations, while acting as a biocide precursor, serves to protect treatment chemicals necessary for corrosion and scale control.

Method of achieving microbiological control in open recirculating

A method for increasing the effectiveness of ozone as a treating agent for alkaline cooling tower waters. This is accomplished by reducing pH of the solutions in contactor loops which supply ozone to cooling tower waters with an acidic substance.
