Patent TW-386253-B (TW)
Title: A method to generate ionized metal plasma using electron beams and magnetic field
Inventor: XU ZHENG
IPC: H05H1/46
Filed: 1998-02-18
Granted: 2000-04-01
Abstract: A deposition system in a semiconductor fabrication system provides at least one electron gun which injects energetic electrons into a semiconductor fabrication chamber to initiate and sustain a relatively high density plasma at extremely low pressures. In addition to ionizing atoms of the extremely low pressure gas such as argon gas at 100 microTorr, the energetic electrons are also believed to collide with target material atoms sputtered from a target positioned above a substrate thereby ionizing the target material atoms and losing energy as a result of the collisions. Preferably, the electrons are injected substantially tangentially to the walls of a chamber shield surrounding the plasma in a magnetic field generally parallel to a central axis of the semiconductor fabrication chamber connecting the target to the substrate. As the injected electrons lose energy ionizing the target material atoms, the electrons spiral inwards toward a central region of the semiconductor fabrication chamber surrounding the central axis, forming an electron cloud in the central region. An arrangement of electron magnets may be positioned adjacent the walls of the chamber shield surrounding the plasma to generate the magnetic field. It is believed that the configuration of magnetic fields also keeps electrons from colliding with the wall of the chamber shield surrounding the plasma.

Title: Gas phase alkylation-liquid transalkylation process
Inventor: GHOSH ASHIM KUMAR
IPC: C07C6/12
Filed: 1998-04-08
Granted: 2004-02-01
Abstract: Process for the production of ethylbenzene by alkylation over a silicalite alkylation catalyst with the subsequent transalkylation of diethylbenzene with the alkylation catalyst and conditions selected to retard xylene production and also heavies production. A feedstock containing benzene and ethylene is applied to a multi-stage alkylation reaction zone having a plurality of series-connected catalyst beds containing a pentasil molecular sieve alkylation catalyst which is silicalite of a predominantly monoclinic symmetry having a silica/alumina ratio of at least 275. The feedstock is supplied to the alkylation reaction zone to cause gas-phase ethylation of benzene at a flow rate to provide a space velocity of benzene over the catalyst to produce a xylene concentration in the product of about 600 ppm or less based upon the ethylbenzene content. Periodically the space velocity may be increased to a value which is greater than the space velocity associated with a minimum concentration of diethylbenzene in the alkylation product such that diethylbenzene production is enhanced while minimizing any attendant transalkylation reactions within the alkylation reaction zone. This is accompanied by a relatively low xylene content in the product, specifically no more than 600 ppm based upon the ethylbenzene in the product. The output from the alkylation reactor is applied to an intermediate recovery zone for the separation and recovery of ethylbenzene with the recovery of a polyalkylated aromatic component which is supplied along with benzene to a transalkylation reaction zone where the polyalkylated aromatic fraction is subject to disproportionation to provide a reduced diethylbenzene content and an enhanced ethylbenzene content. A specific monoclinic silicalite alkylation catalyst has a silica/alumina ratio of at least 300 and has a crystal size of less than one micron.

Title: A total release actuator for use with an aerosol can and a method for total release of the contents of an aerosol can
Inventor: DEMAREST SCOTT W
IPC: B65D83/16
Filed: 1998-05-11
Granted: 2001-07-01
Abstract: A total release actuator for use with an aerosol can having a chime, a dome, and a valve having a valve stem. The actuator has an actuator body with a lower margin defining a skirt rim that attaches to the aerosol can and a central well having a generally horizontal well floor that has a trigger port extending therethrough. The actuator has a trigger that is hingedly attached to the actuator body, preferably at its front end to the front end of the trigger port. The trigger swings downwardly when it is depressed. The trigger extends across the valve stem and includes a downwardly open stem socket that receives the valve stem. The stem socket communicates with a discharge nozzle. The trigger, when moved downwardly, activates the valve, releasing the contents of the can through the discharge nozzle via the stem socket. A latch is attached to preferably each side of the trigger port, extending laterally under the trigger. The latch is elastically deformable, allowing the trigger to pass as it is depressed downwardly and then springing back over the trigger to retain it in the depressed, valve-activating position, allowing can contents to discharge. By this means, a user can release the entire contents of the aerosol can without the user's having to continue to depress the trigger. A method is described of discharging the contents of an aerosol can by use of such an actuator.

Title: A method of manufacturing the via hole
Inventor: CHIAN WEN-JENG
IPC: H01L21/768
Filed: 1998-10-02
Granted: 2000-04-01
Abstract: A method of manufacturing the via hole. The method includes the steps of first providing a semiconductor substrate that has a semiconductor component thereon. Next, active area is manufactured of the semiconductor component and metal contact is also performed on the active area. A metallization layer is deposited on the component in order to interconnect electrically in the integral circuit. An aluminum metallization passivation is deposited on the metallization layer to protect the integral circuit. As defining the via hole, an oxide of aluminum is grown on the metallization passivation. The aluminum oxide has a dense structure and it is not easy to be corroded by hydrochloric acid generated by the reaction between the small amount of chlorine gas in the gas used in dry etching process and water vapor. So it can protect the metallization layer from erode. Then, an anti-reflection layer and passivation layer are deposited on it. Using the technologies of lithography and etching, a via hole is defined to expose the metallization layer and aluminum passivation layer to do the interconnection work.
