IPC: H01L29/94
Filed: 1976-08-20
Abstract: AN ELECTROSTATICALLY BONDED SEMICONDUCTOR-ON-INSULATOR MOS DEVICE, AND A METHOD OF MAKING THE SAME An electrostatically bonded semiconductor-on-insulator and particularly semiconductor-on-sapphire MOS devices are made of bulk materials.  A semiconductor body of a bulk material of less than about 75 microns in thickness is electrostatically bonded to an insulator substrate of a bulk material.  A dielectric layer of between 500 and 2,000 Angstroms in thickness is then formed on the semiconductor body to make a MOS semiconductor device and preferably a MOS field-effect transistor. The semiconductor-on-insulator MOS device is preferably made by first forming a major surface of the dielectric substrate and a major surface of the semiconductor body in planar configurations, applying a metal layer to the opposed major surface of the insulator substrate, and placing the planar surfaces of the body and substrate in intimate contact.  The assembly is then heated to at least 300.degree.C. and preferably at least 700.degree.C. while avoiding oxidation of the contacted surfaces, and thereafter applying an electrical potential of at least 700 volts between said metal layer and the semiconductor body to electrostatically bond the insulator substrate to the semiconductor body.  The electrostatically bonded assembly is then cooled at a rate less than about 10.degree.C. per minute to a temperature of about 300.degree.C. and preferably to room temperature.  Then, a dielectric layer and metal layer are applied on the semiconductor body to complete the semiconductor-on-substrate MOS device.

Title: Regenerateur de pression pour ele
IPC: F22G3/00
Filed: 1977-04-04
Abstract: Partout, dans le domaine de la technique où les vapeurs (d'eau) sont utilisées pour obtenir l'énergie mécanique notamment en centrale électrique - ou dans les autres procédés qui travaillent avec leur chaleur - au moment où les vapeurs, après leurs travaux, se condensent on perd une quantité de chaleur immense (539 Kcal/Kg) ladite << Chaleur d'évaporation >> étant un phénomène naturel. L'appareil qui est traité dans cette demande consiste en une paire (ou plusieurs) de tambours-cellulaires qui prend les vapeurs. Avec l'aide d'une source de chaleur, la pression s'élève consécutivement dans chaque cellule à cause de l'échauffement et de la réception de matière qui a lieu entre les tambours tournant d'après un programme déterminé. Cette construction, permet aussi l'augmentation de la pression et de la température de gaz ou d'air, dans les différents domaines de la techniques. Ses avantages sont : un plus grand rendement thermique (3 fois plus grand que le condenseur) et pour les centrales électriques d'elimination de la source d'eau pour le refroidissement du condenseur et les problèmes liés à la pollution de l'atmosphère.
