  • Patent number: 8734751
    Abstract: A method is provided for recycling and treating the wastes of silicon wafer cutting and polishing processes. To begin with, a dewatered filter cake is mixed with water so that the filter cake is diluted to form a working fluid. The water reacts with silicon in the filter cake to produce silicon dioxide and hydrogen. After the hydrogen is extracted for storage, specific gravity separation takes place via water so that silicon carbide and silicon particles are separated for sorting. Then, solid-liquid separation is performed on the remaining working fluid to separate silicon dioxide (solid) from water and PEG (liquid), before PEG is separated from water. Thus, the useful silicon particles, silicon carbide, silicon dioxide, and PEG are recycled from the filter cake to reduce the total amount of wastes. Moreover, as the side product, hydrogen, is of high commercial value, the method also adds value to recycling.

  • Publication number: 20130298473
    Abstract: The invention provides a plurality of polymeric particles embedded with alkaline-earth metal oxide. The gas-filled polymeric microelements have a shell and a density of 5 g/liter to 200 g/liter. The shell has an outer surface and a diameter of 5 ?m to 200 ?m with the outer surface of the shell of the gas-filled polymeric particles having alkaline-earth metal oxide-containing particles embedded in the polymer. The alkaline-earth metal oxide-containing particles have an average particle size of 0.01 to 3 ?m distributed within each of the polymeric microelements to coat less than 50 percent of the outer surface of the polymeric microelements.

  • Publication number: 20130298472
    Abstract: The invention involves a method of preparing an alkaline-earth metal oxide-containing polishing pad useful for polishing at least one of semiconductor, magnetic and optical substrates. The method includes introducing a feed stream of gas-filled polymeric micro elements into a gas jet, the polymeric microelements having varied density, varied wall thickness and varied particle size. The method passes the polymeric microelements in the gas jet adjacent a Coanda block, the Coanda block having a curved wall for separating the polymeric microelements with Coanda effect, inertia and gas flow resistance. Then it separates various alkaline earth metal oxide constituents from the curved wall of the Coanda block to clean the polymeric microelements.

  • Patent number: 8562389
    Abstract: A polishing pad is described that has a polishing layer with a polishing surface, an adhesive layer on a side of the polishing layer opposite the polishing layer, and a solid light-transmitting window extending through and molded to the polishing layer. The window has a top surface coplanar with the polishing surface and a bottom surface coplanar with a lower surface of the adhesive layer. A method of making a polishing pad includes forming an aperture through a polishing layer and an adhesive layer, securing a backing piece to the adhesive layer on a side opposite a polishing surface of the polishing layer, dispensing a liquid polymer into the aperture, and curing the liquid polymer to form a window.
