Patent CA-2222109-A1 (CA)
Title: Reduction of pattern noise in scanning lithographic system illuminators
Inventor: MCCULLOUGH ANDREW W
IPC: G03F7/20
Filed: 1997-11-25
Abstract: An illumination system for a scanning lithography system used in the manufacture of semiconductor devices having a multiplex array or multi-image array resulting in pattern noise that is reduced by a spatially frequency modulated multiplex array or frequency modulating the pulse rate of a pulsed laser source. A pulsed laser source is used to illuminate a reticle containing a pattern thereon to be reproduced onto a semiconductor. An illumination system using a multiplex array or multi-image array to obtain macro uniformity of an illumination slot or field introduces micro non-uniformity that results in undesirable pattern noise or fixed pattern noise resulting in undesirable imaging properties. The undesirable effects of the pattern noise are eliminated or substantially reduced by spatially modulating the multiplex array in a scanning direction so that the periodic pattern has a linear magnification dependent on position. In another embodiment the pulse rate of the pulsed laser source is frequency modulated.  The present invention improves linewidth control, linewidth variation, and edge roughness.

Title: Flat panel detector for radiation imaging with reduced trapped charges
Inventor: ZHAO WEI
IPC: H01L27/146
Filed: 1995-07-31
Abstract: A flat panel detector (20) for radiation imaging includes an array of transistor switches (38) each of which is associated with a pixel electrode (36). A radiation transducer (CSE) including a top electrode (72) and a radiation conversion layer (70) is disposed over the array. Means are positioned over dead zones between adjacent pixel electrodes to inhibit the accumulation of charge in the radiation conversion layer at the dead zones when the top electrode is biased and the flat panel detector is exposed to radiation. In one embodiment, the inhibiting means is constituted by islands (64) formed of semiconductor material between the array and the radiation transducer. Each island is positioned over a dead zone between adjacent pixel electrodes and contacts a pixel electrode to allow charges accumulated on the islands to drift to the pixel electrodes.

Title: A polysilicon resistor and a method of manufacturing it
Inventor: RYDBERG MATTS
IPC: H01L27/04
Filed: 1996-09-13
Abstract: A resistor has a resistor body (11) of polycrystalline silicon and electrical terminals (23, 15) arranged on and/or in the resistor body (11), so that a resistor portion (13) is formed between the terminals and produces the useful resistance of the resistor. The material of the resistor body is doped with dopants of both acceptor type and donor type. In order to block the charge carrier traps at grain boundaries to a sufficient degree and thereby give the resistor a good stability, also when it is exposed to different substances during the manufacture, the doping is made with donors in such a high concentration, that if only the donor atoms would be present in the material and substantially no acceptor atoms, the material would be to be considered as more or less heavily doped. In particular donor atoms are to be provided in the resistor body in a concentration of at least 3.1019 cm-3, in the case where the material has an average grain size of 1000 .ANG. and phosphorus is used as a dopant of donor type.

Title: Method for assigning band port channels in an unlicensed personal communications system
Inventor: RANADE ASHOK
IPC: H04B1/38
Filed: 1996-03-14
Abstract: A number of RPs stagger the times in which they begin searching for available channels. In a preferred method, one of a plurality of RPs in a UPCS system is selected to have a first start time (520). The system determines which RPs in the system can "see" the selected RP. Each of these RPs is given a unique stagger start time (526). This process may be repeated until each RP in the system is assigned a stagger start time (530). Alternatively, if there are fewer RPs in the system than there are available stagger start times, each RP  may be selected to have a unique stagger start time.

Abstract: A hydraulic servomotor control assembly, for example a hydraulic  servomotor  control  assembly which  supplies  the pressurized oil as operating fluid to a hydraulic motor, and which controls the volume of the pressurized fluid by means of a servo valve.  In hydraulic servomotors of the prior art, the hydraulic motor and the tachogenerator or rotational speed sensor device for detecting the rotation, are two separate entities, so that the servomotor must be quite large, and it is difficult to find ways to make it any smaller.  In contrast to such prior art, the hydraulic servomotor control assembly according to this invention is distinguished by the fact that a hydraulic motor and a rotational speed detector device are shaft coupled and integral with each other,  so that  the resulting assembly is both compact and stable.

Abstract: L'invention concerne une méthode permettant d'allonger sélectivement une amorce oligonucléotidique le long d'une séquence polynucléotidique cible spécifique dans un mélange de polynucléotides. Selon la méthode, on forme l'oligonucléotide modifié ayant une extrémité 3' qui ne peut pas s'allonger le long de n'importe quel polynucléotide, puis on allonge l'amorce oligonucléotidique sélectivement le long de la séquence polynucléotidique cible spécifique en contrôlant la dégradation de l'extrémité 3' de l'oligonucléotide modifié. Ceci permet de sensiblement réduire ou éviter l'extension de l'amorce oligonucléotidique le long de polynucléotides autres que la séquence cible. Dans un autre aspect, l'invention consiste en une amélioration d'une méthode permettant d'amplifier une séquence polynucléotidique cible. Selon la méthode, on dérive l'amorce oligonucléotidique d'un oligonucléotide modifié dont une partie s'hybride avec la séquence polynucléotidique cible à l'exception de l'extrémité 3' de celle-ci, qui possède au moins un analogue de nucléotide incapable de s'hybrider avec un polynucléotide. L'invention concerne également des trousses permettant de mettre en oeuvre ladite méthode.
