One of our key strengths is carbon technology and carbon grippers. That is why we are developing and producing carbon end effectors for wafer handling. We develop and produce all kinds of end effectors for normal wafers from 5 up to 12 inches but also for thin or warped wafers. We develop every end effector system for your specific application.


Our high quality made in Austria endeffectors are design to withstand acid, high movement force, heat differences from extrem cold to extrem heat and still ensure high precision and evenness. 

To insure this properties we produce our own carbon plates and process every step very carefully. Due to the watercutting process we are able to create layers without any deviation to insure evenness. 

With over 500 different existing gripper designs we have the fitting endeffector for every specific application. 


Expectations in the semiconductor industry are getting higher by the day. Thin and warp wafer handling requires even more precision. Still, due to carbon technology and the bernoulli effect we are able to produce high quality end-effectors for thin and warped wafers. 

With the bernoulli effect our grippers are capable of handling thin and warped wafers without really touching them. The wafers get attracted by vaccuum through the suction surfaces and at the same time repelled by compressed air through separate air holes. 


With more than 20 years of experience in wafer handling technology, we were the first ones who invented carbon grippers. 

By producing our own carbon plates, our endeffectors provide the needed stiffness, acid resistance and evenness. 

We develop and produce endeffectors for specific applications and difficult circumstances. Through the bernoulli effect our thin-wafer grippers are capable of handling thin wafers with high movemend speed.
