Decoupled, multiple stage positioning system
InactiveUS20080196631A1Smoother accelerationSmooth decelerationSemiconductor/solid-state device manufacturingPhotographic printingEngineeringHigh velocity
A split axis stage architecture is implemented as a multiple stage positioning system that is capable of vibrationally and thermally stable material transport at high speed and rates of acceleration. A split axis design decouples stage motion along two perpendicular axes lying in separate, parallel planes. A dimensionally stable substrate in the form of a granite, or other stone slab, or of ceramic material or cast iron, is used as the base for lower and upper stages. The substrate is precisely cut (“lapped”) such that its upper and lower stage surface portions are flat and parallel to each other.

The transducer comprises a piezo-composite element comprising a ceramic element embedded in epoxy. In an array, the ceramic elements may be in the form of posts. The plurality of ceramic elements is slightly elevated above the polymer and in staggered arrangement with the polymer. The element is manufactured by first grinding the face of the composite and removing damaged ceramic by acid etching the ceramic. The epoxy is removed by plasma etching so that the ceramic is above the epoxy. The composite is sputter plated so that a maximum temperature that could damage the plating is not exceeded. The ceramic is then poled so that a maximum temperature that could damage the plating is not exceeded. Contacts are then attached to the plating adjacent the ceramic.
