Title: A method of manufacturing the buried contact window
Inventor: SHIE YUNG-FEN
IPC: H01L21/768
Filed: 1998-09-10
Granted: 2000-04-01
Abstract: A method of manufacturing the contact window. The method includes the steps of first providing a semiconductor type substrate that has a dielectric thereon. Next, a contact opening is fromed on the dielectric and part of the substrate is exposed. An ion implantation process is performed on the exposed surface of the substrate at the bottom of contact opening. Then, a passivation layer with the shape of contact opening is formed on the substrate. By annealing process, part of the passivation layer is removed, thus only the passivation layer on the sidewall of the contact is preserved, and substrate at the bottom of the contact opening is exposed. Through Pre-Metal Etch process, the contaminant on the surface of the substrate is removed, and a glue/barrier layer is formed in the contact opening with the same shape and a plug in contact opening is formed.

Title: Trench-gated power MOSFET with protective diode
Inventor: GRABOWSKI WAYNE B
IPC: H01L29/78
Filed: 1999-02-03
Granted: 2000-11-01
Abstract: A power MOSFET includes a trenched gate which defines a plurality of MOSFET cells. A protective diffusion is created, preferably in an inactive cell, so as to form a diode that is connected in parallel with the channel region in each of the MOSFET cells. The protective diffusion, which replaces the  deep centreal diffusion taught in U.S. Patent No. 5,072,266, prevents impact ionization and the resulting generation of carriers near the corners of the gate trench, which can damage or rupture the gate oxide layer. Moreover, the diode can be designed to have a breakdown voltage which limits the strength of the electric field across the gate oxide layer. The elimination of a deep central diffusion permits an increase in cell density and improves the on-resistance of the MOSFET. Specifications for a number of commercially acceptable devices are given.

Title: Virtual network system and method
Inventor: CHIOU CHIUAN-CHENG
IPC: H04L12/00
Filed: 1999-11-25
Granted: 2001-07-01
Abstract: A virtual network system and method is that builds up a virtual network by software simulation under the structure of one machine and multi-user and provides the function of executing the network communication among all end-users. When the network application software of the issuing end intends to send a message, the message is transformed to packets by the communication protocol layers of the virtual network and then sent to the receiving end through the route of the virtual network. The virtual network interface card of the receiving end receives the packets via the virtual NIC upon receiving the notice of message packet. Subsequently the packet is relayed through the driver of the network NIC to the communication protocol layers for unpacking the packets to acquire the message contents. At last the message is sent to the network application software of the receiving end for further processing. All end users not only can communicate one another, but also can communicate with other computer hosts or via internet.
