About

This system is configured as an ICP PECVD deposition tool with 1000 W ICP power, 600 W RF substrate power, and RT-350°C operation. This chamber has 100% SiH_4, N₂, O₂, and Ar for gas sources. The high density PECVD produces a more dense, higher quality SiO₂ and Si₃N₄, as compared with conventional PECVD. With the high density plasma, deposition of high quality films can be done down to below 50°C for processes requiring lower temperatures. Stress compensation for silicon nitride is characterized.
