Abstract:
A method for forming an optical fiber array. A substrate having a first surface and an opposing second surface is provided. The substrate is provided with a plurality of apertures extending through the substrate from the first surface to the second surface. In addition, a plurality of fibers are provided. The fibers have fiber ends with a diameter smaller than the smallest diameter of the apertures. A first fiber is inserted in a first corresponding aperture, from the first surface side of the substrate, such that the fiber end is positioned in close proximity of the second surface. The inserted first fiber is bent in a predetermined direction such that the fiber abuts a side wall of the first aperture at a predetermined position. After the first fiber is bent, a second fiber is inserted in a second corresponding aperture, from the first surface side of the substrate, such that the fiber end is positioned in close proximity of the second surface. The inserted second fiber is bent in conformity with a shape of the first fiber, such that the fiber abuts a side wall of the second aperture at a predetermined position. The bent fibers are bonded together using an adhesive material.
Abstract:
The invention relates to a lithography system, for example for projecting an image or an image pattern on to a target (1) such as a wafer, said target being included in said system by means of a target table (2), clamping means being present for clamping said target on said table. Said clamping means comprises a layer of stationary liquid (3), included at such thickness between target and target table that, provided the material of the liquid (C) and of the respective contacting faces (A, B) of the target (1) and target table (2), a pressure drop (PCap) arises.

Abstract:
A lithography system having one or more lithography elements Each lithography element has a plurality of lithography subsystems. The lithography system further has a control network forming a control network path between the plurality of the lithography subsystems and at least one element control unit for communication of control information. The lithography system is arranged for: issuing control information to the at least one element control unit to control operation of one or more of the lithography subsystems for exposure of one or more wafers; issuing a process program to the element control unit. The process program has a set of predefined commands and associated parameters. The element control unit is arranged to transmit a command of the process program to a lithography subsystem to be executed by the lithography subsystem, regardless of an execution status of a preceding command transmitted to the lithography subsystem.
