    摘要: An alignment apparatus for aligning a substrate, and a substrate processing system including such alignment apparatus. The alignment apparatus includes an alignment base for supporting the substrate and/or a substrate support member. A force generating device applies a contact force on the substrate. The force generating device includes an arm including a rigid proximal end and a rigid distal end. The distal end is provided with a contact section for contacting an edge of the substrate and an elastically deformable arm section extending between the proximal and distal ends. The connection part connects the proximal end to the alignment base. The arm is movable with respect to the alignment base via the connection part. The alignment apparatus also includes an actuator for causing a displacement of the proximal end, whereby the contact force, defined by the elastically deformable arm section, is applied to the substrate by the contact section.

    摘要: Fiber feedthrough device (50), for forming a hermetic seal around optical fibers in a flat fiber group (60) with a group width. The device comprises a slotted member and a base (62). The base defines a hole (65) that extends entirely through the base along a feedthrough direction (X), and is adapted to accommodate the slotted member. The slotted member (52) defines first and second surfaces (53) on opposite sides associated with the feedthrough direction, and a side surface (55, 56) facing transverse to the feedthrough direction. The slotted member comprises a slot (58), which extends along the feedthrough direction through the slotted member, and opens into the first and second surfaces and into a longitudinal opening (59) along the side surface. The slot extends transversely into the slotted member up to a slot depth at least equal to the fiber group width.

    摘要: A sub-beam aperture array for forming a plurality of sub-beams from one or more charged particle beams. The sub-beam aperture array comprises one or more beam areas, each beam area comprising a plurality of sub-beam apertures arranged in a non-regular hexagonal pattern, the sub-beam apertures arranged so that, when projected in a first direction onto a line parallel to a second direction, the sub-beam apertures are uniformly spaced along the line, and wherein the first direction is different from the second direction. The system further comprises a beamlet aperture array with a plurality of beamlet apertures arranged in one or more groups. The beamlet aperture array is arranged to receive the sub-beams and form a plurality of beamlets at the locations of the beamlet apertures of the beamlet array.

    摘要: A measurement system for measuring an input electrical current (Ics) from a current source (CS) and generating a current measurement signal, comprising a current measuring circuit (70) having a first input terminal (72) connected to the current source and an output terminal (74) for providing the current measurement signal. The current measuring circuit further comprises one or more power supply terminals (75, 76) arranged to receive one or more voltages from a power supply (77a, 77b) for powering the current measuring circuit. The current measuring circuit also comprises a first voltage source (VD) coupled to the one or more power supply terminals, the first voltage source providing a disturbance voltage to the one or more power supply terminals, the disturbance voltage representing a voltage at the first input terminal.
