Spin on glass process
WebA two step etch back process is then used to further planarize the layer and remove the spin-on-glass from the conducting layer surface. The process is designed to avoid over etching into the patterned conducting layer at the edges of the elevated regions of the DRAM, where the spin-on-glass is by its very nature thin. WebSpin-on-glasses (SOGs) are known materials used in the fabrication of semiconductor devices. SOGs are primarily used to planarize a semiconductor wafer, but are also used as …

WebMaleic acid catalyzed hydrolysis and condensation of tetramethoxysilane was carried out in 1-propoxy-2-propanol to prepare a spin-on-glass (SOG) material for the trilayer imaging process. The material was found to be stable enough for industry use. Minor amounts of methylsilsesquioxane and photoacid generators were introduced into the material. WebFeb 4, 1991 · Spin-on-glasses (SOGs) are known materials used in the fabrication of semiconductor devices. SOGs are primarily used to planarize a semiconductor wafer, but are also used as interlayer dielectrics, passivation layers, and sacrificial etch-back layers.
