Abstract:
A method for rapidly depositing a borosilicate glass film on a semiconductor wafer within a chemical vapor deposition (â€œCVDâ€ ) reaction chamber, the method comprising:controlling the pressure within the chamber; introducing oxygen into the chamber; introducing a carrier gas into the chamber; injecting triethyl borate (â€œTEBâ€ ) and tetraethyl orthosilicate (TEOS) into the chamber; stabilizing the injection of TEB and TEOS, comprising the stabilization of the TEB flow through the chamber; 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 4,500 angstroms per minute.
