Latest Patents
Franceschi holds a patent for an "Active damper for semiconductor metrology and inspection systems." This invention features a damper that includes a pair of parallel plates with a fluid of variable viscosity retained between them. The design incorporates at least one wire positioned between the plates, which may consist of multiple sets of lands and grooves. In certain implementations, both plates are equipped with intermeshed lands and grooves. A controller is designed to provide current to the wire, allowing for the adjustment of an electromagnetic field or current through the fluid. The fluid utilized may be a magnetorheological or electrorheological fluid, with its viscosity being variable based on the electromagnetic field or current. The controller's ability to vary the current applied to the wire enables the adjustment of the fluid's viscosity, thereby altering the damping of the semiconductor metrology or inspection system in response to the movement of the stage. This patent represents a significant advancement in the field, showcasing Franceschi's innovative spirit.
