Title: Electric short circuit at pn-junction prevention method for CMOS type EEPROM
Inventor: GREGOR RICHARD WILLIAM
IPC: H01L21/8247
Filed: 1995-11-18
Abstract: The method involves etching a pn-junction section field oxide next to the pn-junction for its exposure. A further or drain-wash implantation is carried out to position the exposed section of the pn-boundary layer under the field oxide to remove the exposed section.In the mfr. of a source/drain arrangement a field oxide over part of the pn-junction is etched for the junction exposure. After a further or drain-wash implantation, a conductive layer is formed over a substrate part adjacent to the field oxide.

Abstract: The apparatus levitates a non-magnetic solid body, or a volume of gas or liquid, and comprises a chamber (3) incorporating a number of preferably permanent or coil magnets (5, 7, 9, 11) holding a quantity of a magnetic fluid (13). The magnets are positioned such that they generate a levitated cavity (15) holding the non-magnetic solid body, or sample of a volume of gas or liquid and which is free of  magnetic fluid (13). The non-magnetic body or sample is held in the pre-determined position, and is returned to this position by the influence of the magnets (5, 7, 9, 11) in the event of position drift. The cavity (15) does not touch the chamber (3) walls (17) other than at a single point at which the wall may be opened or closed. The chamber (3) has a Peltier heating/cooling element. Sensors around the chamber detect movement of the cavity (15) and hence accelerations. The chamber is employed to grow crystals which are not limited by a hard wall. The fluid from which the crystals are grown is introduced to the cavity (15) to which concentrates are added from time to time.

Abstract: A method for operating a drive unit, especially for an injection unit of an injection moulding machine and comprising a first electric motor (14) for rotating a shaft (7) carrying an axially fixed threaded sleeve (15) driven by a second electric motor (20) involves rotating the sleeve (7) with the second motor (20) to produce axial shaft (7) movement or rotating the shaft (7) with the first motor (14).  An increase in the dynamics of the drive unit during the acceleration or retardation phases of the axial shaft (7) movement using one of the motors (14, 20) is achieved by rotating the other motor (20, 14) briefly in the same direction and assists the acceleration or retardation of shaft (7) axial movement.      Also claimed is a method where the maximum injection speed can be increased by rotating the shaft (7) in the opposite direction to the sleeve (15) and a decoupling device (21) can be opened between the shaft (7) and the driven unit (2) to prevent rotation of the latter.
