    摘要: An improved reading structure (110) for performing a read operation in an array of multiple bits-per-cell flash EEPROM memory cells is provided. A memory core array (12) includes a plurality of memory cells, each being previously programmed to one of a plurality of memory conditions defined by memory core threshold voltages. A reference cell array (22) includes a plurality of reference core cells which are selected together with a selected core cell and provides selectively one of a plurality of reference cell bit line voltages defined by reference cell threshold voltages. Each of the reference cells are previously programmed at the same time as when the memory core cells ar being programmed. A precharge circuit (36) is used to precharge the array bit lines and the reference bit lines to a predetermined potential. A detector circuit (28) is responsive to the bit line voltages of the reference cells for generating strobe signals. A reading circuit (26) is responsive to the strobe signals for comparing the memory core threshold voltage with each of the reference cell threshold voltages.

    摘要: An output buffer is disclosed for an integrated circuit having a varying number of simultaneously switching outputs. As fewer outputs on the integrated circuit are simultaneously switching, the ouput conductance of certain logic gates within each of the output buffers on the integrated circuit is increased by sharing intermediate nodes (PUCOM, PDCOM) between each of the output buffers. Consequently, the speed of the output buffer increases as fewer of the outputs simultaneously switch and internally generated noiseis small. Conversely, as additional outputs simultaneously switch, the output conductance of certain logic gates within the output buffer is decreased, resulting in reduced speed of the output buffers and a corresponding reduction in internally generated noise.

    摘要: A collimator system for use in PVD sputtering of semiconductor wafers having multiple tiers provided between a target and wafer substrate. The collimator system prevents target atoms from contacting the wafer at substantially oblique angles, thereby providing good step coverage uniformity over the surface of the wafer. Additionally, the presence of more than one tier prevents localized build-up of target atoms that occurs in conventional single tier collimators, thereby providing good flat coverage uniformity over the surface of the wafer.

    摘要: In a process for cultivating mushrooms wherein a substrate (10, 20) of mushroom compost is pasteurised before adding mushroom spawn, at least one ventilation passage (14, 23) is formed in the core of the substrate before and/or after adding the spawn whereby air is free to circulate through the substrate to control the temperature of the substrate during the pasteurisation and/or spawn running processes.

    摘要: Procédé pour rendre plane une structure de circuit intégré (30) par un procédé en deux étapes comportant: application sur une couche de métallisation (40, 42, 44) comportant une ou plusieurs ouvertures (46, 48) d'une couche d'isolation (50') suffisamment mince pour éviter la formation de criques dans la partie d'isolation appliquée dans les ouvertures de la couche de métallisation, lissage de la couche d'isolation par retrait des parties élevées de l'isolation par exemple par attaque par voie sèche de l'isolation, application d'une autre couche d'isolation (70) sur la première couche d'isolation et lissage de l'autre couche d'isolation par retrait des parties élevées par exemple par attaque par voie sèche; ainsi, la surface d'isolation lisse résultante sera essentiellement plane et exempte de criques. Dans un mode préférentiel de réalisation, un second matériau, par exemple un matériau de photoréserve (60, 80), est enduit sur la couche d'isolation avant l'étape de lissage, en particulier lors de l'utilisation d'un procédé d'attaque par voie sèche anisotrope, afin de garantir que seules les parties élevées de la couche d'isolation sont retirées lors de l'étape d'attaque.

    摘要: Procédé de fabrication d'un dispositif à circuit intégré, comprenant le revêtement d'une couche réfléchissante (10) avec un revêtement antiréfléchissant (12) comportant une couche d'arséniure d'indium avant l'application d'une couche de matériau photosensible ou photorésistant (14) pendant la production du dispositif. La lumière traversant le matériau photosensible (14) est absorbée par le revêtement antiréfléchissant (12), si bien que seule une quantité minime de lumière nécessaire pour l'alignement est réfléchie à travers le matériau photosensible (14), se qui résulte dans une définition de rayonnement plus nette dans le matériau photorésistant et une meilleure commande du procédé. La couche d'arséniure d'indium antiréfléchissante (12) est appliquée avec une épaisseur d'au moins 500 Angstroems et est en outre caractérisée par un degré de refléxion de 10 à 25% relativement indépendant de l'épaisseur du revêtement et de la longueur d'ondes de la lumière dans la gamme de fréquence normalement utilisée pour l'exposition d'un matériau photorésistant.

    摘要: PCT No. PCT/GB85/00040 Sec. 371 Date Sep. 30, 1985 Sec. 102(e) Date Sep. 30, 1985 PCT Filed Jan. 29, 1985 PCT Pub. No. WO85/03318 PCT Pub. Date Aug. 1, 1985.A frond line (10) for filtering particulate material from currents flowing over a river or sea bed comprises a substantially continuous curtain of randomly overlapping elongate buoyant elements (15) extending transversely in a common direction from a longitudinally folded web (35), the base of each element (15) being gripped between the superposed portions of the folded web. A frond mat is produced by combining spaced parallel rows of the frond lines (10) with spaced generally parallel cross-straps (13) to provide an open grid mat structure. Anchoring straps (20) depend from the mat, each strap carrying a ground anchor plate (12) which is driven into the river or sea bed by a powered driving tool. The frond line (10) is produced by laying discrete transverse strips (31) of synthetic buoyant material along the web (35) so that equal lengths extend from opposite sides of the web (35), folding the web (35) longitudinally, and then securing the superposed portions of the web to one another.
