    摘要: A method for rapidly depositing a borosilicate glass film on a semiconductor wafer includes controlling the pressure within the chamber, introducing oxygen into the chamber, introducing a carrier gas into the chamber, injecting triethyl borate (nullTEBnull) and tetraethyl orthosilicate (nullTEOSnull) into the chamber, stabilizing the injection of TEB and TEOS, adjustably spacing a heater relative to the chamber, introducing ozone gas into the chamber, and depositing borosilicate glass film at a rate of at least about 4,500 angstroms per minute.
