  • Patent number: 11302512
    Abstract: An electron beam apparatus includes an electron optics system to generate an electron beam, an object table to hold the specimen at a target position so that a target portion of the specimen is irradiated by the electron beam, and a positioning device to displace the object table relative to the electron beam. The positioning device includes a stage actuator and a balance mass. The stage actuator exerts a force onto the object table to cause an acceleration of the object table. The force onto the object table results in a reaction force onto the balance mass. The balance mass moves in response to the reaction force. The positioning device enables the balance mass to move in a first direction in response to a component of the reaction force in the first direction.

  • Patent number: 9495495
    Abstract: One or more systems and methods for scan cell assignment for a design layout of a semiconductor arrangement are provided. The design layout is evaluated to identify a set of sequential cells, such as flip flops connected to circuitry by data paths. Sequential cells within the set of sequential cells are assigned to either a scan cell assignment or a non-scan cell assignment based upon a control path criterion, a register bank criterion, a pipeline depth criterion, a sequential loop criterion, or other criteria to create a cell assignment list. Scan paths are connected to sequential cells assigned to the scan cell assignment so that test patterns can be sent to and received from such sequential cells during testing of the semiconductor arrangement for defects. Power, performance, and area utilization are improved because at least some sequential cells are assigned to the non-scan cell assignment.
