Patent EP-0243148-A1 (EP)
Inventor: MALPASS DENNIS BENEDICT
IPC: C07F3/02
Filed: 1987-04-22
Abstract: The viscosity of hydrocarbon solutions of dialkylmagnesium com­pounds is reduced by including as the viscosity reducing agent a nitrogen-­containing compound which is a piperidine substituted with a hydrocarbyl group (preferably a C₁-C₆ alkyl, C₆-C₉ aryl or C₅-C₆ cycloalkyl group) at the 2-position and optionally further substituted, triethylamine, cyclo­hexylamine, dicyclohexylamine, or N-N-dimethylformamide, or a mixture of two or more of these nitrogen-containing compounds. The viscosity reduc­ing agent may be used as such or in the form of a substance produced by reacting such a nitrogen-containing compound with magnesium or with a dialkylmagnesium compound. The viscosity reducing agent may be used alone, or in a mixture with an organoaluminum viscosity reducing agent.

Inventor: ROZMUS WALTER J JR
IPC: B28B3/00
Filed: 1987-12-24
Abstract: A powder is disposed in a sealed container (12) which is encapsulated in a pressure transmitting medium (16) contained within a pot die (26) of a press. A ram (24) enters the pot die (26) and applies a force to the pressure transmitting medium (16) and the container (12). The pressure transmitting medium (16) transmits pressure omni-directionally about the container (12). The container (12) has an impermeable, cellular structure (12) that collapses and permanently deforms as the powder (14) compacts. The container (12) does not substantially expand to its initial shape after being removed from the pressure transmitting medium (16) and therefore saves the compacted powder (14ʹ) from resilient forces of the container (12) tending to rebound the container (12) to its initial shape.

Filed: 1988-11-03
Abstract: This invention relates to a semiconductor device and manufacturing method thereof capable of stably connecting a diffusion region adjacent to an oxide film for separation of element and a wiring formed on a insulation film. To achieve this object, in this invention, a contact hole is formed in the insulation film so as to remove the edge of the oxide film for separation of element, and a conductive film is formed in the contact hole, and a second diffusion region is formed so as to partly overlap with the first diffusion region through the conductive film, and a wiring is connected to the conductive film. In this constitution, the contact hole may be formed in a sufficiently large size without being defined by the edge of the oxide film for separation of element, and consequently a stable connection is obtained. Furthermore, since a final diffusion region is formed after forming the contact hole, the position and size of the final diffusion region may be always optimized with respect to the contact hole. Accordingly, the mask matching margin of the contact hole and the first diffusion region may be sufficiently maintained widely. Thus, according to this invention, the reliability and productivity of the semiconductor device may be enhanced.
