Abstract: Actuation systems and lithographic apparatus which address the issue of uncontrolled return of common mode currents are provided. In an embodiment such systems aim to prevent the occurrence of corona and discharge between high voltage electric cables in low pressure environments. An exemplary actuation system includes an actuator module, a power source and power transmission cables. The actuator module includes an electrical motor and a first plurality of shielded cables configured to connect to the electrical motor at one end. The actuator module is located in a low pressure environment and each shield of the first plurality of cables is grounded. The transmission cables electrically connect the first plurality of cables with power supply, and include an extra cable configured to connect each shield of the first plurality of cables with the first extra cable, via a choke so as to provide a return path for common-mode currents.

Abstract: A power supply for providing HV power to a lithography illumination source comprising a HV power source arranged to provide the HV power, a HV power transmission line arranged to transmit the HV energy from the HV power source and one or more RF terminations provided on one or more of an input end of the transmission line or an output end of the transmission line. The one or more RF terminations terminate the transmission line to reduce reflection of RF energy at the end of the transmission line.

Abstract: Consistent with an example embodiment, an electronic device comprises a semiconductor device, particularly an integrated circuit, and a carrier substrate with conductive layers on the first side and the second side, and voltage supply and ground connections mutually arranged according to a chessboard pattern. These connections extend in a direct path through vertical interconnects and bumps to bond pads at the integrated circuit, which bond pads are arranged in a corresponding chessboard pattern. As a result, an array of direct paths is provided, wherein the voltage supply connections form as much as possible the coaxial center conductors of a coaxial structure.

Abstract: Consistent with an example embodiment, an electronic device comprises an integrated circuit and a carrier substrate with a bottom and top conductive layer, and is provided with voltage supply, ground and signal transmission connections. In order to enable the use of more than one supply voltage, the integrated circuit is subdivided into core functionality and peripheral functionality, and the carrier substrate is subdivided into a corresponding core area and peripheral area. The ground connections of both core and periphery are mutually coupled through an interconnect in the carrier substrate. This interconnect is particularly a ground plane, and allows the provision of a transmission line character to the interconnects for signal transmission of the periphery.

Abstract: In order to provide a gradual increase in supply current following an apparatus switch-on, the invention proposes a device and method for selectively activating different data processing parts of the apparatus in sequence following switch-on. The device proposed for implementing the invention comprises a shift register (10) and logic circuitry (20). The shift register (10) and logic circuitry (20) receive a common master clock CLK and generate a plurality of sub-clocking signals CLK0-CLK3 which, whilst being identical in frequency and in phase with one another, are arranged to only assume a normal free running condition, one at a time following the initial switch-on. The respective sub-clocking signals are connected to clock inputs of respective data processing parts of the apparatus. Providing such separate sub-clocking signals ensure a gradual start-up and shut-down and helps to avoid problems associated with a heavy current draw at switch-on or off.
