Title: Method for forming metal wiring of semiconductor device
Inventor: KIM HEON-DO
IPC: H01L21/28
Filed: 1996-06-28
Granted: 1997-04-11
Abstract: A method for forming a metal wiring of a semiconductor device which involves a double aluminum alloy deposition, namely, a deposition of a first aluminum alloy layer to a thickness corresponding to a portion of the entire wiring thickness at a low temperature, in such a manner that it is fixed in the contact and deposition of a second aluminum alloy layer, to a thickness corresponding to the remaining wiring thickness portion which is deposited at a higher temperature. The deposition of the first aluminum alloy layer is carried out at a temperature of 25 to 150 deg.C and a pressure of 0.5 to 4.0 mTorrs using electric power of 5 to 10 KW whereas the deposition of the second aluminum alloy layer is carried out at a temperature of 200 to 400 deg.C and a pressure of not higher than 4.0 mTorrs using electric power of not more than 10 KW. The first aluminum alloy layer is also thermally treated at a temperature of 200 to 400 deg.C for 60 to 180 seconds prior to the deposition of the second aluminum alloy layer. In accordance with this method, it is possible to improve in step coverage, thereby improving the reliability of the wiring.

Title: A smoke detection system, a replaceable filter cartridge for the filter means of a smoke detector system and a smoke detector
Inventor: STEVENSON HUGH
IPC: G01N1/00
Filed: 1997-04-30
Granted: 1999-06-21
Abstract: A smoke detection system comprises a manifold connected to a series of sampling pipes. A fan which draws a large volume of sampling air through the sampling pipes is connected to the inlet manifold and a small proportion of that air is directed to the inlet of a smoke detector, the outlet of which is connected to the manifold. The configuration obtained by the connection of the outlet from the detector into the inlet manifold provides a large pressure drop across the flow path through the detector. As a result of the large pressure drop, a filter for removing dust and other contaminants can be incorporated in the flow path and the filter can also incorporate a fine filtering stage to produce a secondary clean air flow which can be directed into the detector to prevent smoke particles from settling on critical components of the detector.
