Title: Method of gap filling using high-density plasma chemical vapor deposition
Inventor: LIOU JR-JIAN
IPC: H01L21/205
Filed: 1998-07-02
Granted: 2001-04-11
Abstract: A method of gap filling by using high-density plasma chemical vapor deposition (HDPCVD). On a substrate having a conductive structure, a first oxide layer is formed to protect the conductive structure. While forming the first oxide layer no pressure bias is applied. A high-speed argon flow and a high etching/deposition rate is provided to form a second oxide layer and generate an etching effect on the edge and corner of the first oxide layer to form a triangular or trapezium profile. Then, a low-speed argon flow and a low etching/deposition rate is provided to form a third oxide layer. The gap filling is completed without resulting in voids, while maintaining the reliability and yield of the device.

Title: The trench isolation method of deep sub-micron process
Inventor: WU SHIE-LIN
IPC: H01L21/76
Filed: 1998-07-13
Granted: 2000-09-01
Abstract: This invention provides a method of manufacturing the shallow trench isolation (STI). It adopts the oxide layer as the hard mask for silicon etch, and uses LPCVD to grow the amorphous film to overcome the difficulties of step coverage. A silicon oxynitride thin film is formed around the edge of the trench to avoid the gate wrap-around and the cornor parasitic leakage current. Use the thick pad oxide as the etch hard mask to form the shallow trench isolation (STI) on the substrate of the semiconductor. Next, form a thermal oxidation thin film to recover the etched damage. Form a silicon oxynitride layer on the thermal oxidation thin film; next, deposit an undoped LPCVD amorphous layer on the silicon oxynitride layer and fill up the shallow trench isolation (STI). Next, proceed the oxidation method to transfer the amorphous layer into thermal oxide. Finally, use CMP method to remove the oxidation thin film and the silicon oxynitride layer outside the shallow trench isolation (STI).

Title: Positive temperature coefficient polymer composites composition
Inventor: WENG BIING-JYH
IPC: C08K3/04
Filed: 1998-08-25
Granted: 2001-10-21
Abstract: This invention relates to a positive temperature coefficient element, which is prepared by kneading mixture of mesophase microbeads (MPMB) and high-density polyethylene (HDPE), and then pressing with metal foil. The composition of MPMB in the mixture is 65 to 40% in volume, and preferably 55 to 50%. The average partical size of MPMB is 3 to 30 μm. The spherical MPMB improves kneading processing of mixture. An addition of 1 to 10% MPMB in volume to the mixture of HDPE and carbon block for PTC composites effectively reduces difficulty in kneading process. Tests show that volume resistance coefficient of this invention is smaller (below 10 ohm-cm) compared with ceramic PTC. Volume resistance coefficient for electric break-down reaches above 1000 ohm-cm. Low-resistance and small-volume PTC elements can be made by this invention, which is beneficial to the present market for compact electrical-circuit design.

Title: Limiting access to private networks in cellular communications systems
Inventor: WESTERBERG LARS ERIK
IPC: H04L12/56
Filed: 1998-08-31
Granted: 2001-04-11
Abstract: A mobile cellular communications system and method are disclosed, which limit access to private network cells only to mobile terminals that are used by subscribers to those private networks. In cells belonging to the public network, only information about the public cells is broadcast on the public system information control channels. This public cell information is thus the only cell information that the non-subscribers' mobile terminals are able to terminal belonging to a subscriber of one or more private networks surfaces in a public cell, the public network transmits a radio link control message to that mobile terminal, which contains information about the candidate cells for selection associated with the private network(s) involved. The private network transmits system information via the private cell to a subscribing mobile terminal about the private and public cells' neighboring cells. Consequently, the subscribing cells. Consequently, the subscribing mobile terminal will regard the public network cells and private network cells as integral parts of the overall cellular system. Cells associated with private networks to which that mobile terminal's end user is a ""non-subscriber"" are thus ""invisible"" to that mobile terminal.

Title: Multi-color image forming apparatus
Inventor: EMUKAI TETSUROU
IPC: G03G15/16
Filed: 1998-10-31
Granted: 2001-09-21
Abstract: The present invention is to prevent the slipping off of toner image forming position by diminishing the speed fluctuation of intermediate transcription belt. The intermediate transcription belt (7) is rotated by the first speed. In order to transcribe twice the multi-color toner image on the intermediate transcription belt (7) onto the recording paper, the secondary transcription roll (9) is pressed against the intermediate transcription belt (7) only during the secondary transcription. The secondary transcription roll (9) is rotated by the driving means containing gear apparatus (24) at a big circumference speed faster than the first speed. The torque limiter (28) limits the driving torque of the secondary transcription roll (9) when it is pressed by the intermediate transcription belt (7) to the load torque of the secondary transcription (9) when it is alienated from the intermediate transcription belt. Consequently the secondary transcription roll (9) is controlled to rotate at the same speed or a little bit faster speed than the intermediate transcription roll (9), and the load of the second transcription roll (9) applied on the intermediate transcription belt (7) will not exceed a predetermined value.

Title: Formation method of anti-fouling thin film
Inventor: LIN TIAN-TSAI
IPC: C23C14/34
Filed: 1998-11-18
Granted: 2001-07-01
Abstract: This invention describes the formation method of anti-fouling thin film, which utilizes reactive vacuum sputtering to deposit tetrafluoroethylene resin and ITO composite thin film onto substrates of ferrous metal or non-ferrous metal, ceramic, glass and stone to form anti-fouling thin film with high transparency and low absorption. The anti-fouling function results from the characteristics of tetrafluoroethylene such as low sticking, low friction coefficient, weather resistance, extremely low surface energy and its capability to dispel water and oil to prevent dust and foul sticking. However, it is a material with high insulation capability and thus can easily cause electrostatic adsorption. The conductive ITO is employed to composite within the resin to make the electric resistance of the substrate below 10<SP>9</SP> Ω-cm and thus become semiconductive. The problem that the substrate tends to carry static electricity can be resolved. This thin film can be used in fields of architectural materials, glass windows, precision instruments, optical industry, automobile materials, information field (DVD, CD, VCD) and surface treatment.
