Title: Process for preparing a silicon melt from a polysilicon charge
Inventor: HOLDER JOHN DAVIS
IPC: C30B29/06
Filed: 1998-10-14
Granted: 2001-04-11
Abstract: A process for preparing a silicon melt from a polysilicon charge, for use in the production of single crystal silicon ingots by the Czochralski method, in a crucible which has a bottom, a sidewall formation, a centerline which is substantially parallel to the sidewall formation and which intersects a geometric centerpoint of the bottom, and a radius extending from the centerline to the sidewall formation. In the process, the crucible is loaded with chunk polysilicon to form a charge having a bowl-like shape, wherein initially the load generally slopes radially upwardly and outwardly from the centerline toward the sidewall formation to an apex and then slopes generally downwardly and outwardly from the apex to the sidewall formation. The bowl-shaped chunk polysilicon charge is heated to form a partially melted charge, and graular polysilicon is fed onto the partially melted charge to form a mixed charge of chunk and granular polysilicon. As the mixed charge is further heated to form a silicon melt, the unmelted chunk polysilicon present above the melt surface acts to deflect any molten silicon that may be splattered as granular polysilicon rapidly melts and hydrogen is released.

Title: Method for securing over-the-air communication in a wireless system
Inventor: PATEL SARVAR
IPC: H04L12/28
Filed: 1999-07-31
Granted: 2001-05-16
Abstract: In the method for securing over-the-air communication in wireless system, a mobile sends a system access request and dummy data associated with the system access request to a network. The network sends a first data stream including a first data portion to the mobile in response to the system access request and the dummy data. The mobile extracts the first data portion from the first bit stream, and sends a second bit stream to the network. The second bit stream includes a second data portion. The mobile and the network both generate a key based on the first data portion and the second data portion, and establish a first encrypted and authenticated communication channel in cooperation using the key. The mobile then transfers authorizing information to the network over the first encrypted and authenticated communication channel. If accepted, a second encrypted and authenticated communication channel is established. The network then sends sensitive information such as the root or A-key to the mobile over the second encrypted and authenticated communication channel.

Abstract: This invention provides a method of diminishing the critical dimension of two bit lines on both sides of lower storage node for a memory cell on semiconductor wafer. This semiconductor chip includes a silicon substrate, a silicon oxide layer formed on silicon substrate, a polysilicon layer formed on top of the silicon oxide layer and two line-shaped photoresist layers having rectangular cross section formed on the surface of polysilicon layer, which is used to define the positions of two-bit lines. The smallest dimension in between two vertical side edges of these two photoresist layers is called the critical dimension. In this invented method, the semiconductor wafer is placed in a plasma gas pressure chamber to perform a dry etching process in order to diminish the critical dimension of this photoresist layer, in which the reacting gas of C2F6, O2 and He flows in to strip off a predetermined thickness of two vertical side edges of the photoresist layer. Then, the part of polysilicon layer that is not covered with the photoresist layer is completely removed to preliminarily form the two bit lines.

Title: Prevention device for frequency transformer high frequency leakage current and the method thereof
Inventor: SHIU SHR-CHANG
IPC: H02P7/29
Filed: 1999-09-28
Granted: 2001-08-11
Abstract: A common mode transformer structure is disclosed, wherein the common mode transformer is formed of a ring-shaped ion core having circular cross section, a tri-phase winding, and a damping resistance short-circuit connected in the winding. When the common mode current flows to the common mode transformer, it will generate magnetic flux in the iron core, but the normal mode current and differential mode current won't generate the magnetic flux, therefore, the common mode transformer plays the role of damping resistance. In addition, the present invention relates to a method to reduce the leakage current between the pulse width modulation transformer and a motor, wherein a common mode transformer is added between the frequency transformer and the motor. This method can greatly reduce the peak value, the effective value, and the average value of the leakage current, and thereby greatly improve the problems of electromagnetic interference of frequency transformer and current mis-operation.
