Title: Method for producing polysilicon contact window
Inventor: JENG BO-JIE
IPC: H01L21/768
Filed: 1996-11-08
Granted: 2000-02-21
Abstract: olysilicon contact window by opening a smaller contact window on the polysilicon after deposited, using a photolithography and etching technique to form two polysilicon lines which is connected by a polysilicon pad therein to constitute a polysilicon, route and forming a metal line and the opening of the contact window is smaller than the width of the metal line. Therefore, the metal line can fully cover the polysilicon inside the contact window in order to solve the problem where a broken circuit is liable to form in the wet etching step of the metal and increase the yield of the products. Meanwhile, since the metal is fully covered on the polysilicon inside the contact window, the wet etching process designed to avoid damage to the polysilicon can be eliminated thereby increasing the productivity of the process.

Granted: 2000-10-01
Abstract: The invention relates to a registration process used for registering at least one dual mode mobile station (MMS) with an associated domestic base station (DBS). The domestic base station is connected to the public telephone network (PSTN, ISDN) and uses, for transmission and reception, some frequencies which are close to or identical to those used in a cellular radio system. The dual mode mobile station can operate either in ""wireless"" mode, used to communicate via the said domestic base station, or in ""cellular"" mode, used to communicate via base stations (BTS) within the cellular radio system. Registration of the dual mode mobile station with the domestic base station constitutes a preliminary phase enabling the operation of the dual mode mobile station in ""wireless"" mode, whereby, following each incoming or outgoing call; a communication can be established between the dual mode mobile station and another telephone equipment, via the domestic base station. According to the invention, the registration process consists of an exchange of signals according to a preset protocol based on a preset frequency hopping low, allowing to determine over which frequency each signal must be transmitted, and on a preset uplink start-up frequency, over which the dual mode mobile station transmits the first signal. The frequency hopping law and the uplink start-up frequency being specific to, and known by, the dual mode mobile station and associated domestic base station.

Filed: 1998-05-07
Granted: 2000-07-11
Abstract: A process for the recovery of ethane, ethylene, propane, propylene and heavier hydrocarbon components from a hydrocarbon gas stream is disclosed. The stream is divided into first and second streams, and the second stream is expanded to the fractionation tower pressure and supplied to the column at a mid-column feed position. A recycle stream is withdrawn from the tower overhead after it has been warmed and compressed, and is combined with the first stream. The combined stream is cooled to condense substantially all of it, and is thereafter expanded to the fractionation tower pressure and supplied to the fractionation tower at a top column feed position. The pressure of the compressed recycle stream and the quantities and temperature of the feeds to the column are effective to maintain the column overhead temperature at a temperature whereby the major portion of the desired components is recovered.
