Abstract:
PROBLEM TO BE SOLVED: To provide a system and a method that utilize efficient patterning means. SOLUTION: A device-manufacturing method uses patterning apparatus that increases the number of individually controllable elements to be simultaneously programmed, in order to increase update speed of an array of the individually controllable elements, and the system includes a lithography apparatus. Thus, the number of high-speed analog inputs required for the array is decreased, thereby complexity of the array is reduced, and the maximum update speed of the array is increased. Furthermore, the number of elements in the array can be increased easily. The patterning apparatus is divided into a plurality of cell groups, and the lithography apparatus includes a plurality of supply channels. Each supply channel is disposed, such that it supplies a voltage signal to each cell that corresponds to the cell group. Thus, the number of inputs required for individually addressing each cell to the patterning apparatus is reduced. COPYRIGHT: (C)2007,JPO&INPIT

PROBLEM TO BE SOLVED: To provide a safety system for preventing a collision of a support with another parts, for a lithographic apparatus which has a stationary magnet motor for driving the support such as a substrate support or a patterning device support. SOLUTION: A measurement system for measuring the position of the support. The measurement system measures a magnetic field strength of an alternating magnetic field generated by a magnet assembly of the stationary magnet motor, and/or measures generation of eddy currents in a metallic layer shielding the magnet assembly in combination with an inductance measurement of an electromagnet generating the alternating magnetic field causing the eddy currents, and/or measures light using an optical position sensitive sensor such as a CCD metric or linear photodiode positioned in a light plane emitted by an emitter.

Abstract:
The present invention comprises a lithographic apparatus and device manufacturing method that uses a patterning device that increase a number of individually controllable elements that are programmed simultaneously to increase an update rate of an array of individually controllable elements. A number of required high speed analog inputs to the array is reduced. The complexity of the array is reduced and the maximum update speed of the array is increased. Furthermore, the number of elements within an array can be readily expanded. The patterning device can be divided into a plurality of groups of cells and the lithographic apparatus can comprise a plurality of supply channels. Each supply channel can be arranged to provide a voltage signal to each cell in a respective group of cells. This can reduce the number of required inputs to the patterning device for individually addressing each cell.
