The Tystar 3600 is an LPCVD furnace system intended for deposition of low-stress silicon nitride and low-temperature oxide. The Tystar 3600 uses process gases including silane, dichlorosilane, and ammonia. The Tystar 3600 supports wafer boats for 2 inch, 3 inch, 4 inch, and 6 inch wafers.[1]

Vacuum

250 mTorr[1]

Gas delivery

100 sccm (high flow), 20 sccm (low flow)[1]

What it is

The Tystar 3600 is configured with a Furnace Control System (FCS-10) touchscreen interface and a separate Data Capture System (DCS-30) computer. The system is intended for deposition of low-stress silicon nitride (Si3N4, LSN) and low-temperature oxide (LTO).[1]

How it works

The Tystar 3600 utilizes two separate tubes: Tube 1 for low-stress nitride processes and Tube 3 for low-temperature oxide processes. The default deposition temperature for low-stress nitride is 835 °C with a pressure of 250 mTorr. For low-temperature oxide, the default temperature is 450 °C. Process gases include ammonia (NH3), dichlorosilane (DCS), and silane. The system also includes an exhaust abatement system (Jupiter Scientific Callisto) for treating process exhaust.[1]

Applications

The Tystar 3600 supports two primary deposition processes: low-stress silicon nitride (LSN) using ammonia and dichlorosilane, and low-temperature oxide (LTO) using silane-based chemistry. Specific recipes provided for Tube 1 are LSNITR.001 and STNITR.001, and for Tube 3 is LTO.003.[1]
