PZ 250 CAP – Description
The PZ 250 CAP WL was developed for the precise positioning of semiconductor wafers with diameters up to 12”. In closed-loop operation the actuator offers motion in Z direction of 250 μm. Equipped with a capacitive sensor that overcomes hysteresis and drift, single steps in nanometers can be achieved. Specified positions can be held with high stability for a long periods. Due to its high stiffness, the PZ 250 CAP WL can carry loads up to 3 kg.
The PZ 250 CAP WL is well suited for applications in the semiconductor industry, solar panel production, lithography, and mask inspection.
