Description
The Sandvik LPCVD consists of 4 furnace tubes, with maximum temperature of 1050 C for each one:
Tube 1: Wet/Dry Silicon Oxide growth. Wet/Dry oxide: This tube uses the Si substrate to grow SiO2. Wet oxide refers to the use of water vapor as the source of oxygen and dry oxide uses O2 gas. Since water molecules can penetrate through the substrate more, wet oxide technique results in thicker oxides and faster growth rate. Wet oxide deposition on the tool is limited to 5 hours. BYU has an excellent online calculator you can use to find out how much time your process would take for a given thickness and temperature. https://cleanroom.byu.edu/oxidetimecalc
Tube 2: Low Stress Silicon Nitride deposition. This tube is designated to low stress silicon nitride.
Tube 3: Clean anneal. This tube is an RCA clean wafer only anneal tube, with N2 and H2N2 gases.
Tube 4: General anneal. This tube is a general anneal tube, with N2 and H2N2 gases
Applications
- Wet/Dry Silicon Oxide growth
- Low Stress Silicon Nitride deposition
- Annealing with N2 or H2N2 gases
