Intelligent Vacuum Metrology
Open the catalog to page 1Intelligent Vacuum Transducers for 1200 to 5 x 10-10 mbar Joy in innovation is our main driving force for developing vacuum metrology at its best. The new generation of Smartline sets highest standards with regard to precision, functionality and reliability. Durability That Pays Off The THYRACONT Pirani with extended measuring range activates ionization sensors below a very low pressure threshold. This protects the sensors and improves gauge life. Stay Connected The latest transducers offer an RS485 interface and an additional 0-10 V output or EtherCAT. Time Is Money Smartline‘s...
Open the catalog to page 2Application Example Silicon nitride is used in the semiconductor industry as an insulating material or for masking. It is deposited by PECVD (plasma-enhanced CVD) or LPCVD (low pressure CVD). The feeding of the coating system is done via a load-lock to continuously keep the vacuum in the process chamber at 10"2 to 1 mbar. Challenge The pressure must be measured accurately while evacuating the air lock, in order to take in the wafer into the process chamber at the earliest possible moment to start the coating process. At last the processed wafer is returned to the load-lock. After venting...
