Abstract:

A stable suspension of ethylpolysilicate nanoparticles having a size of between about 5 nm and 120 nm are in water and stabilized with between about 0.05 and 5 weight percent tetraalkylammonium hydroxide. The particles are between about 95% and 99.5% hydrolyzed and have superior removal rates when used in chemical mechanical polishing. A process for making ethylpolysilicate nanoparticles includes the step of adding reverse osmosis water and 25% tetramethylammonium hydroxide and ammonium hydroxide to a reactor, agitating the mixture and heating the mixture to about 80 C. Tetraethylalkoxy silane is added to the mixture and the mixture stirred and hydrolyzed. Ethanol is then removed. The mixture was then subjected to a vacuum to remove additional distillate. The material left in the reactor was then transferred to a plastic drum.

International Classification:

C08G 77/02

US Classification:

528425

Abstract:

An stable ethylsilicate polymer having a dynamic viscosity of 10 centipoises (cps) to 1,000 cps at 25 C. and 50 wt % to 60 wt % silica (SiO). The stable ethylsilicate polymer includes not greater than 1 wt % of TEOS monomer. The process of forming the ethylsilicate polymer includes a two step addition of catalysts. A hydrolysis catalyst is added initially, for example hydrochloric acid, and a second catalyst is added subsequently, such as phosphonitrilic chloride trimer. The ethylsilicate polymer is used to form MQ resins.

Abstract:

An MQ resin including at least 30% SiO, preferably at least 50 wt % SiO, and having dynamic viscosity of 50 centipoises (cps) to 750 cps at 25 C. is produced from a stable ethylsilicate polymer. The ethylsilicate polymer includes not greater than 1 wt % of TEOS monomer. The ethylsilicate polymer is produced by a two step addition of catalysts wherein a hydrolysis catalyst, for example, hydrochloric acid is added initially and a second catalyst, such as phosphonitrilic chloride trimer, is added subsequently.
