Title: A controlled cleavage process
Inventor: HENLEY FRANCOIS J
IPC: H01L21/762
Filed: 1998-05-11
Abstract: A technique for forming a film of material (12) from a donor substrate (10). The technique has a step of introducing energetic particles (22) in a selected manner through a surface of a donor substrate (10) to a selected depth (20) underneath the surface, where the particles have a relatively high concentration to define a donor substrate material (12) above the selected depth and the particles for a pattern at the selected depth. An energy source such as pressurized fluid is directed to a selected region of the donor substrate to initiate a controlled cleaving action of the substrate (10) at the selected depth (20), whereupon the cleaving action provides an expanding cleave front to free the donor material from a remaining portion of the donor substrate.

Patent CA-2297243-A1 (CA)
Inventor: OSOVETS ALEXANDER
IPC: G06T1/20
Filed: 1999-05-21
Abstract: Les contrôleurs de processeur numérique comprennent une mémoire RAM p, ex, une mémoire d'instruction qui consomme une quantité d'énergie importante pendant son fonctionnement. Pour réduire la consommation d'énergie lorsque des instructions répétitives, ou boucles, sont exécutées, ces boucles sont stockées dans un registre à décalage (SRB) et sollicitées à partir de ce dernier plutôt que de la mémoire RAM, sans instruction spéciale de définition de la boucle. Une commande de mémoire comprend un moteur de suivi d'état (STM) qui surveille l'exécution des instructions de programme et détermine en fonction de cette exécution à quel moment une boucle a été commencée, puis elle permet au registre à décalage de produire les instructions de boucle mémorisées dans ce dernier et bloque la production d'instructions par la mémoire d'instruction jusqu'à ce que la boucle soit achevée. Ce processus est automatiquement initié pour chaque boucle qu'il s'agisse d'une nouvelle boucle, d'une boucle à l'intérieur d'une autre boucle ou d'une boucle multiple. Ce contrôleur ne nécessite pas d'instructions spéciales précédant ou suivant la boucle pour déterminer les points de début ou de fin de boucle, le nombre d'instructions comprises dans la boucle ou le nombre de fois qu'une boucle est exécutée, mais détermine la présence d'une boucle automatiquement à partir des instructions exécutables microprogrammées qui régissent l'exécution de la boucle.
