The PECVD is the left chamber of the two-chamber unit. It has 4 gas channels, one purge line, and a 13.56 MHz RF power source capable of delivering 500 watts. The system is computer controlled, and users can select and run recipes. The system can deposit silicon oxide and silicon nitride.
The Dielectric RIE is the right chamber of the two-chamber unit for dry etching SiO2 and SiNx. The RIE chamber has 4 gas channels and one purge line. The RF power source is at 13.56 MHz and capable of 500 watts. The system is computer controlled by recipes, which can be run by the user.
This instrument has material restrictions. Consult the allowed materials list for this instrument in FOM.
