Filed: 2001-05-17
Granted: 2002-05-21
Abstract: When an ultraviolet sterilizer is used in a room free of a person, left and right light shield doors are opened to expose ultraviolet lamps outwardly. When an operation switch on a control panel is then turned on, an operation start timer is actuated, and the ultraviolet lamps are then energized to sterilize surrounding surfaces after elapse of 5 minutes. When the ultraviolet sterilize is used in a room occupied by a person, the left and right light shield doors are closed to direct the ultraviolet lamps inwardly until all light shield doors are brought into a substantially triangular prism. When the operation switch on the control panel is then turned on, the ultraviolet lamps and a fan are energized to draw external air from an air inlet. The drawn air passes through an inner radiation chamber defined inwardly of the light shield doors that have been combined into the substantially triangular prism. The air is sterilized by ultraviolet, radiation emitted from the ultraviolet lamps and discharged from an air outlet.

Title: Recording of result information in a built-in self-test circuit and method therefor
Inventor: LEDFORD JAMES S
IPC: G11C29/44
Filed: 2002-04-04
Granted: 2004-01-01
Abstract: An integrated circuit has a built-in self-test (BIST) controller (10) that has a sequencer (16) that provides test algorithm information for multiple memories (44, 46, 48, 50). The sequencer identifies the test algorithm that is to be performed and multiple memory interfaces (32, 34, 36, 38) interpret the output of the sequencer and perform the algorithm on the multiple memories. The multiple memories may be different or the same regarding type, size, data widths, etc. Having multiple memory interfaces provides flexibility to tailor the test algorithm for each memory, but yet keeps the advantage of a single source of identifying the test algorithm. With the memories being non-volatile, timing information with regard to the test algorithm is stored in the memories. When test algorithms fail or complete execution, pertinent BIST information is stored in non-user addressable space of the multiple memories.

Title: Method of forming ruthenium thin film using plasma enhanced process
Inventor: PARK KYUNG-WOONG
IPC: H01L21/205
Filed: 2002-12-17
Granted: 2007-01-11
Abstract: A conventional method of forming a ruthenium thin film has a problem that conditions for improving a surface morphology are contrary to those for improving a step coverage, with respect to an oxygen fraction, a pressure, a temperature, etc. Accordingly, it is difficult to obtain a thin film having the improved properties in both the surface morphology and the step coverage. This invention provides three methods for improving both the surface morphology and the step coverage. As one method of forming the ruthenium thin film, a ruthenium seed layer is first formed using a PECVD process and then a ruthenium thin film is deposited using a thermal CVD process. As another method, a first ruthenium thin film is deposited using thermal CUD process and then a second ruthenium thin film is formed on the first ruthenium thin film using a PECVD process. As further another method, a ruthenium thin film is deposited using a thermal CVD process and then a surface of the ruthenium thin film is processed using an oxygen containing plasma. According to these methods, both the surface morphology and the step coverage can be improved.
