ICP-PECVD (Unaxis VLR)
This system is configured as an ICP PECVD deposition tool with 1000 W ICP power, 600 W RF substrate power, and 50°C-350°C operation. This chamber has 100% SiH4, 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 deposited as low as 50°C for processes requiring lower temperatures. Stress compensation for silicon nitride is characterized.
A Deposition and Etch chamber are both attached to the same loadlock, allowing etching and deposition without breaking vacuum. Each chamber can be scheduled separately on SignupMonkey.
