Charged particle beam device

When using a charged particle beam aperture having a ring shape in a charged particle beam device, the charged particle beam with the highest current density immediately above the optical axis, among the charged particle beams is blocked, so that it is difficult to dispose the charged particle beam aperture at the optimal mounting position. Therefore, in addition to the ring-shaped charged particle beam aperture, a hole-shaped charged particle beam aperture is provided, and it is possible to switch between the case where the ring-shaped charged particle beam aperture is disposed on the optical axis of the charged particle beam and the case where the hole-shaped charged particle beam aperture is disposed on the optical axis of the charged particle beam.

Impedance adjustment device
11791134 · 2023-10-17 · ·

An impedance adjustment device includes a variable capacitor unit. A microcomputer changes the capacitance value of the variable capacitor unit by switching on or off PIN diodes included in n capacitor circuits separately. Thus, the impedance on the plasma generator side when viewed from a high frequency power supply is adjusted. When changing the capacitance value of the variable capacitor unit to a target capacitance value, the microcomputer changes the capacitance value to a relay capacitance value different from the target capacitance value. The microcomputer changes the capacitance value to the target capacitance value after the capacitance value is changed to the relay capacitance value.

Methods and circuits for asymmetric distribution of channel equalization between devices

A transceiver architecture supports high-speed communication over a signal lane that extends between a high-performance integrated circuit (IC) and one or more relatively low-performance ICs employing less sophisticated transmitters and receivers. The architecture compensates for performance asymmetry between ICs communicating over a bidirectional lane by instantiating relatively complex transmit and receive equalization circuitry on the higher-performance side of the lane. Both the transmit and receive equalization filter coefficients in the higher-performance IC may be adaptively updated based upon the signal response at the receiver of the higher-performance IC.
