...., deposition of intermetallic dielectrics). In the PECVD process, the gaseous precursors are most commonly subjected to time-varying electric fields of frequencies in the range of 50 kHz to 13.5 MHz. In some designs, microwave frequencies are also used. The electric field initially reacts primarily with the...
