When most people hear the word "semiconductor" they think of processing speed. When folks like us hear "semiconductor" we think of process purity. The microscopic topography of today's silicon circuits demand the cleanest manufacturing facilities on earth. We know that, and we build liquid level, flow and pressure sensors to meet those stringent requirements. It's because of these special requirements we have a special semi- conductor sensor team at Gems. These men and women are dedicated to making your manufacturing clean and simple. Gems Sensors Inc. offers semiconductor equipment manufacturers...

APPLICATIONS Gems features product for more applications than you can shake a sensor at, so we can't begin to list them all. This short list should give some guidance for the typical usage of Gems sensor products in semiconductor manufacturing. We urge you to remember that our engineering capability allows us to develop specially configured sensors, so please don't hesi- tate to ask about a product or application not shown in this brochure. PROCCESING APPLICATION TYPICAL SENSOR DEPOSITION EQUIPMENT (CVD/PVD) Use on cooling line around deposition chamber Control vacuum in deposition chamber Monitor...

Gems has conducted extensive extraction testing to allay any concerns regarding leaching of trace metals from the metal shaft inside the stem of our LS-300TFE. The sensors were immersed in high purity acid for as long as 38 days. The results, illustrated below, show negligible amounts of elements extracted; the possibility of media contamination is remote. PureSense LS-700 Liquid Level Sensor Electropolished stainless steel liquid level sensor ideal for high purity solvents, photoresists, pyrophoric compounds, and specialized CVD chemicals. Compact design suitable for level sensing in the smallest...
