Then, a developing process is applied to the photoresist layer for forming a photoresist pattern. Then, the photoresist pattern is used as the etching mask to etch the conductive layer so as to form conductive wires and remove the conductive layer on the outer peripheral of the wafer. Afterwards, a dielectric layer is formed on the wafer. Finally, a photolithography process is applied to the dielectric layer for defining an opening in the dielectric layer on the inner peripheral of the wafer.

Title: Video signal transmission
Inventor: LINNARTZ JOHAN PAUL MARIE GERA
IPC: H04N21/235
Filed: 1999-11-08
Granted: 2002-05-11
Abstract: This invention relates to the generation of an MPEG video stream, which contains several slightly different programs, each with approximately the same content. The MPEG stream is constructed in such a manner that a simple transcoder can effectively select one of the programs. This is achieved by storing the differences relative to the default program in selected user data fields. The transcoder is little more than an MPEG bit stream parser, which replaces the bits corresponding to a selected set of macroblocks by the replacement data stored in the user data fields. A standard MPEG decoder without any knowledge of the embedded user data fields will simply extract the default program. One application of the invention relates to broadcasting of a television program with and without a logo, or a commercial with and without a public warning. Another application relates to copy-protection schemes. In such a scheme, the default program contains a ticket indicating that the contents may be copied once. Upon recording, this ticket is removed and replaced by the content accommodated in the user data field.

Title: In-situ post-develop inspection performing in polysilicon etch platform system
Inventor: LIOU JR-GANG
IPC: H01L21/66
Filed: 1999-11-26
Granted: 2002-07-11
Abstract: This invention provides an in-situ after develop inspection (ADI) performing in polysilicon etch platform system. In conventional technique, only several wafers in a lot will undergo ADI and the mean value of the ADI is used to represent ADI resist width of every wafer in the lot. However, the ADI resist widths of individual wafers vary in a significant fashion and, therefore, the mean value of resist widths of several wafers can not be used to represent every wafer in the lot. The inventive method provides a scanning electron microscope installed in a polysilicon etch platform system for ADI, which enables ADI for every wafer in a lot and performing etching process to form gate structure according to the ADI result individually. The method consists of following step: (a) placing a wafer in a polysilicon etch platform system, which contains polysilicon material for the formation of gate structure and developed resist for the definition of the gate structure; (b) performing ADI in a wafer orienter chamber to check if the developed resist width is within the manufacture specification; and c adjusting etching recipe for the manufacture of gate structure according to the ADI result to modify the resist width and thus manufacture the gate structure.
