摘要
A novel method of high-rate deposition of silicon dioxide from organic compounds at low temperature was studied. The new method is called light projection chemical vapor deposition (CVD) utilizing an ArF excimer beam. Tetramethylorthosilicate (TMOS) and hexamethyldisilazane (HMDS) are suitable source materials. This method enables the deposition of fine SiO2 patterns without subsequent photolithography. High deposition rates of about 3500 A/min from TMOS and about 2000 A/min from HMDS were obtained at 2°C.
