pBN Heaters & Electrostatic Chucks
For High Temprature Semiconductor Processing
pBN Heaters and Chucks (ESC)
pBN/PG heaters operate at 1700°C and higher with excellent thermal uniformity (2°C on wafer) in an ultra-high vacuum. As nonbrittle refractory materials, they owe their exceptional purity to a high-temperature chemical vapor deposition production method which makes them chemically inert to most corrosive gases and liquids and unaffected by most molten metals. Momentive Technologies can even custom-design heater chucks (ESC) for your high-temperature (up to 1000°C) wafer handling needs.
Wafer handling at elevated temperatures can be challenging. Pyrolytic Boron Nitride Electrostatic Chucks (pBN ESCs) can hold wafers at temperatures exceeding 1000°C, making them the most versatile ESCs on the market. Wafers can be kept within very tight temperature ranges due to the high-density, multizone heating elements. pBN ESC’s high thermal shock resistance means it is mechanically robust even when exposed to rapid temperature swings.
- Momentive Technologies Pyrolytic Boron Nitride Electrostatic Chucks offer ultra-fast J-R chucking at the widest range of temperatures on the market, from 0 to 1000°C
- The materials selected for our heaters result in thermal shock resistance and exceptionally low thermal mass allowing for ramp rates of 100°C/min
- pBN is a fully dense material, making it ultra-high vacuum ready
