Publication number: 20070109510Abstract: A lithographic apparatus and method in which an illumination system supplies a projection beam, a patterning system imparts to the beam a pattern in its cross section, and a projection system projects the patterned beam onto a target portion of a substrate. The projection system comprises an array of lenses spaced from the substrate such that each lens in the array focuses part of the patterned beam onto the substrate. A displacement system causes displacement between the lens array and the substrate. A particle detector detects particles on the substrate which are approaching the lens array. A free working distance control system increases the spacing between the lens array and the substrate in response to detection of a particle. The lens array is moved away from the substrate as the detected particle passes the lens array. Thus damage to the lens array can be avoided.Type: ApplicationFiled: December 29, 2006Publication date: May 17, 2007Applicant: ASML Netherlands B.V.Inventors: Pieter Willem De Jager, Cheng-Qun Gui, Peter Spit, Eduard Hoeberichts

Publication number: 20070052943Abstract: A lithographic apparatus and method include an illumination system that supplies a beam of radiation, an array of individually controllable elements that pattern the beam, and a projection system that directs the patterned beam a substrate supported on a substrate table. The projection system defines a pupil. Either the pupil or the array of individually controllable elements is imaged onto a target portion of the substrate. The projection system includes an array of lenses with each lens in the array arranged to direct a respective part of the patterned beam onto a respective part of the target portion of the substrate. In one example, each of the individually controllable elements is selectively controllable to direct a respective part of the beam away from the pupil such that the proportion of the beam passing through the pupil is adjusted.Type: ApplicationFiled: November 14, 2006Publication date: March 8, 2007Applicant: ASML Netherlands B.V.Inventor: Pieter Willem De Jager

Publication number: 20070046919Abstract: Provided is a method and system for facilitating use of a plurality of individually controllable elements to modulate the intensity of radiation received at each focusing element of an array of focusing elements to control the intensity of the radiation in the areas on the substrate onto which the focusing elements direct the radiation.Type: ApplicationFiled: November 6, 2006Publication date: March 1, 2007Applicant: ASML Netherlands B.V.Inventors: Cheng-Qun Gui, Arno Bleeker, Pieter Willem De Jager

Publication number: 20070026325Abstract: A distortion measurement apparatus comprising a detector arranged to measure distortion of a substrate, and a processor arranged to receive distortion data indicating the measured distortion of the substrate and to transform the distortion data into a frequency domain representation. The distortion data may alternatively be transformed into an orthogonal polynomial or an orthonormal polynomial representation.Type: ApplicationFiled: July 29, 2005Publication date: February 1, 2007Applicant: ASML Netherlands B.V.Inventors: Antonius Theodorus Maria Derksen, Pieter Willem De Jager, Erik Jose Smeets

Publication number: 20050190354Abstract: A diffractive optical MEMS device includes a plurality of parallel planar reflective surfaces and an actuator system. The actuator system is used to adjust the position of each of the planar reflectors in a direction perpendicular to the planar reflectors to change characteristics (e.g., phase, intensity, etc.) of light interacting with the device.Type: ApplicationFiled: February 27, 2004Publication date: September 1, 2005Inventor: Pieter Willem de Jager

Patent number: 5113146Abstract: An amplifier arrangement includes a transistor differential pair (N1, N2) having an input terminal (3) and an output terminal (4). The transistor differential pair is coupled to a current mirror (P1, P2). A first level shifting circuit (6) and a second level shifting circuit (7) stabilize the d.c. voltage levels on the mutually coupled main electrodes of the differential pair (N1, N2) and the current mirror (P1, P2) respectively. Consequently, the influence of the Early-effect on the differential pair is suppressed and an improved linear signal transmission is obtained from the input terminal (3) to the output terminal (4). The level shifting circuit (6) also provides a base current compensation in order to produce a high input impedance and the second level shifting circuit (7) provides a base current compensation for equal adjusting currents through the differential pair to reduce any offset voltage.Type: GrantFiled: March 12, 1991Date of Patent: May 12, 1992Assignee: U.S. Philips Corp.Inventors: Willem de Jager, Eetze A. de Boer

Patent number: 4961046Abstract: By compensating for the base-emitter voltage of the transistor T.sub.1 by means of the base-emitter voltage of the transistor T.sub.4 the voltage U.sub.z across the impedance Z is made equal to the input voltage U.sub.i. The current I.sub.z through the impedance Z and the equal output current I.sub.O are then proportional to the input voltage U.sub.i and are highly linear.Type: GrantFiled: August 11, 1989Date of Patent: October 2, 1990Assignee: U.S. Philips Corp.Inventor: Willem De Jager

Patent number: 4951003Abstract: A amplifier circuit comprises first transistor (T.sub.1) and a second transistor (T.sub.2) whose emitters are each connected via a first resistors (R.sub.1) to a point (2) which is connected to the power-supply terminal (3) by means of a current source (1). The bases of said transistors are connected to input terminals (4,5) and via a second resistor (R.sub.2) each to the base of a third transistor (T.sub.3) whose emitter is connected to the terminal (2). The linearity of the circuit is improved by arranging a fourth transistor (T.sub.4) and a fifth transistor (T.sub.5) in series with the collector-emitter paths of the first transistor (T.sub.1) and the second transistor (T.sub.2) which fourth and fifth transistor have their bases connected to a reference terminal (7) and have their emitters interconnected by means of a third resistor (R.sub.3).Type: GrantFiled: May 16, 1989Date of Patent: August 21, 1990Assignee: U.S. Philips Corp.Inventors: Willem De Jager, Evert Seevinck

Patent number: 4857861Abstract: The first (T.sub.1) and the second (T.sub.2) output transistor of an amplifier arrangement are push-pull driven by means of a drive circuit (10) having two transistors (T.sub.11, T.sub.12) which are each loaded by a current source (T.sub.13, T.sub.14). Currents which are a measure of the currents flowing through the first (T.sub.1) and the second (T.sub.2) output transistor are generated by first (20) and second (30) current measuring means. These currents are applied to a control circuit (40) which controls the current intensity of the current sources (T.sub.13, T.sub.14) in such a way that the harmonic mean value of the currents flowing through the first (T.sub.1) and the second (T.sub.2) output transistor is substantially equal to a reference value.Type: GrantFiled: March 2, 1988Date of Patent: August 15, 1989Assignee: U. S. Philips CorporationInventors: Evert Seevinck, Willem De Jager, Buitendijk
