Title: Method to prevent the residual copper layer in the copper damascene process from blocking the alignment mark
Inventor: CHEN YING-HE
IPC: H01L21/304
Filed: 2001-07-25
Granted: 2004-01-01
Abstract: The present invention discloses a method to remove the residual copper layer blocking the alignment mark of the semiconductor substrate in a copper damascene process. The feature of the present invention is that, when the device region forms the damascene pattern to connect with the integrated circuit, the semiconductor substrate has the vacant region of the alignment mark and also has a dummy pattern on it, so that the removal rate of the copper layer in the vacant region speeds up when chemical mechanical polishing process is proceeded on the semiconductor substrate to remove the copper layer. Thus, the problem that the residual copper layer blocks the alignment mark is prevented.

Title: Method for pretreating dielectric layers to enhance the adhesion of CVD metal layers thereto
Inventor: WESTHOFF RICHARD C
IPC: H01L21/3205
Filed: 2001-11-16
Granted: 2002-11-01
Abstract: A method for chemical vapor deposition comprises providing a quantity of nitrogen at the interface between a transition metal-based material and an underlying dielectric-covered substrate. The nitrogen can be provided by heating the substrate in an atmosphere of a nitrogen-containing process gas or by exposing the surface of the dielectric-covered substrate to a plasma generated from a nitrogen-containing process gas. In certain embodiments, the nitrogen on the surface of the dielectric is bound with atoms of a transition metal to form a thin layer of a transition metal nitride. The method promotes the adhesion of the transition metal-based layer to the dielectric by nullifying the effect of halogen atoms that are also incorporated at the transition metal/dielectric interface.

Title: Memory system having stub bus configuration
Inventor: YOO CHANG-SIK
IPC: G11C11/407
Filed: 2002-02-08
Granted: 2003-09-01
Abstract: A memory system having a stub-bus configuration transmits a free-running clock through the same path as data signals. A single clock domain is employed for both read and write operations. For both operations, the read or write clock signal is routed through the same transmission path as the data, thereby increasing system transfer rates by maximizing the window of data validity. In this manner, data bus utilization is increased due to the elimination of a need for a preamble interval for the strobe signal, and pin count on the memory module connectors is therefore reduced.

Title: Output buffer circuit having low noise and method
Inventor: SHIAU MING-CHUEN
IPC: H03K19/017
Filed: 2002-06-14
Granted: 2007-12-01
Abstract: The prevent invention provides a novel output buffer circuit having low noise and method. The circuit is simple in structure and can effectively prevent the ground voltage level from floating and avoid the generation of noise, so as to increase the stability of the whole chip. The output buffer circuit is added with an over-current absorbing circuit 1 between a PMOS transistor M1 and an NMOS transistor M2 serially connected to form a CMOS inverter. When input signal IN transits from high level to low level, the PMOS transistor M1 is turned on and the NMOS transistor M2 is turned off. At this moment, the over-current absorbing circuit 1 is on for absorbing partial drain current of the PMOS transistor M1 and decreasing the base current of the first NPN transistor Q1, thereby decreasing the collector current (i.e., output current) transiently flowing through the second NPN transistor Q2. Consequently, the current change rate of the output current becomes moderate, and the maximum value of the output current becomes smaller, thereby not only effectively depressing transient voltage difference induced on the ground terminal, but also avoiding the floating of ground voltage level and the generation of noise for increasing the stability of the whole chip.

Abstract: The invention relates to a cushioning body having an L-letter shaped cross section, in which the thickness at the end of the L-letter is thicker than that at the corner portion. Specific constitutions for meeting the thickness requirement include the followings: (1) fixing member-guiding grooves are formed such that the depth thereof becomes deeper from the ends of the L-letter toward the corner portion, thereby making the thickness of the cushioning body based on the bottom portion of the fixing member-guiding groove gradually reducing from the ends of L-letter toward the corner portion; (2) without forming the fixing member-guiding grooves, the cushioning body is molded so that the thickness of itself is gradually reduced from the ends of L-letter to the corner portion; and (3) protrusions are formed outside at both ends of the L-letter of the cushioning body. When bound with a fixing member, the cushioning body prevents the binding force of the fixing member from concentrating on the corner portion.
