Spin on glass process
WebSpin on Glass (SOG), an interlayer dielectric material applied in inorganic liquid form to fill narrow gaps in the subdielectric surface for planarization, is an alternative to silicon dioxide using CVD processes and CMP processes. SOG has similar electrical properties with SiO/sub 2/ as an intermetal dielectric layer. In this experiment the main features looked for … WebTo overcome these hot points appropriate technological steps are added to the bonding process: O 2 plasma and hot HNO 3 exposure of glass/silicon respectively silicon nitride surfaces, one minute delay of spinning after sog-deposition on the substrate, increasing up to 125°C the annealing temperature of the spun-on-glass. Smooth, uniform ...

Webfor "spin-on-glass" or sol-gel coatings). On the other hand, photoresists usually undergo other processes, depending on the desired application/use. Common Defects Found When Spin Coating There are a number of defects/features that are characteristic of spin-coated films. Comets: These usually occur when relatively large solid particles WebDec 1, 2004 · Introduction The spin-on-glass (SOG) is a well-known technology for the process forming a dielectric layer between metal lines in low-cost fabrication of IC circuits. The dielectric layer is called ‘inter-metal dielectric (IMD)’. There are two types of SOG [1]. One is the inorganic silicate-based SOG and the other is organic siloxane-based SOG.
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. WebA process for forming a tetraethylorthosilicate based spin-on-glass comprising the steps of: forming a dilute nitric acid solution consists essentially of between approximately 7.5% to 9.0% by volume of de-ionized water, between approximately 89% to 91% by volume of isopropyl alcohol, and balance nitric acid;
Webing the spin-coat process, an insoluble residue (usually a fine silicate dust) is produced. This residue can be a major source of particles on the wafer surface. These particles can … WebDec 1, 2004 · In this article, a case of Spin-on-Glass (SOG) process-induced tungsten residue was reported. The case was found after the tungsten etchback process of filling vias. A possible failure mechanism was proposed. Based on the review of our process flow, it is believed that the tungsten residue might result from the hydrodynamic effects of SOG.
