Application of silica sol in field of microelectronics

Abstract

The invention discloses an application of silica sol in the field of microelectronics, and provides an application of novel silica sol in the field of microelectronics. According to the application ofthe silica sol in the field of microelectronics, the silica sol is produced by Hubei Jinwei New Material Co., Ltd., the raw material in the silica sol is Australian sand, and the silica sol is produced under a closed full-automatic condition; filling and packaging are conducted under a thousand-grade dust-free condition; and filtering is conducted by adopting a 0.2-micron filtering system. By improving the silica sol produced by Hubei Jinwei New Material Co., Ltd, the properties of the produced silica sol in all aspects meet the use requirements of the field of microelectronics, and a new wayis opened up for wide application of domestic silica sol in the field of microelectronics. The mass of the raw material is selected, the used raw material is imported Australian sand, and the metal ion content of the product is reduced from the source.

Description

technical field [0001] The invention relates to the technical field of microelectronics, and more specifically, to the application of a silica sol of Hubei Jinwei New Materials Co., Ltd. in the field of microelectronics. Background technique [0002] For a long time, the silica sol used in the field of microelectronics has relied on imports, and the domestic silica sol cannot meet the production needs of the field of microelectronics due to the limitation of raw materials and processing technology. Take Hubei Jinwei New Material Co., Ltd. as an example. Although it is a large-scale silica sol manufacturer in China, its products are mainly used in various refractory binders, coating industry, thin shell precision casting and paper industry. The performance can not meet the production needs of the microelectronics field. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a kind of application of silica sol produced by Hubei Jinwei New Mater...
