Title: SRAM (static random access memory) manufacturing method
Inventor: Wang zhi-ming
IPC: H01L21/8244
Filed: 1998-05-04
Granted: 1999-12-01
Abstract: This invention discloses a manufacturing method of dual gate oxide and buried contacts for SRAM (static random access memory). After the gate oxide is formed, immediately form above it a polysilicon layer and use this polysilicon layer to define the gate oxide, thus photoresist contamination of the gate oxide can be avoided. The process is combined with the photolithography process for buried contact, while removing the gate oxide of the periphery circuit region, thus the use of a mask can be eliminated. After completing the cell gate oxide process in the memory region, use a one time oxidation process to finish the making of the gate oxide periphery circuit region, making the control of its thickness and quality easier.

Title: System and method of selectively cleaning copper substrate surfaces, in-situ, to remove copper oxides
Inventor: NGUYEN TUE
IPC: H01L21/3213
Filed: 1998-05-13
Granted: 2000-10-11
Abstract: A system and method of selectively etching copper surfaces free of copper oxides in preparation for the deposition of an interconnecting metallic material is provided. The method removes metal oxides with <beta>-diketones, such as Hhfac. The Hhfac is delivered into the system in vapor form, and reacts almost exclusively to copper oxides. The by-products of the cleaning process are likewise volatile for removal from the system with a vacuum pressure. Since the process is easily adaptable to most IC process systems, it can be conducted in an oxygen-free enviroment, without the removal of the IC from the process chamber. The in-situ cleaning process permits a minimum amount of copper oxide to reform before the deposition of the overlying interconnection metal. In this manner, a highly conductive electrical interconnection between the copper surface and the interconnecting metal material is formed. An IC having a metal interconnection, in which the underlying copper layer is cleaned of copper oxides, in-situ with Hhfac vapor, is also provided.

Title: Para-xylene production process
Inventor: ABICHANDANI JEEVAN SAHIB
IPC: C07C15/08
Filed: 1999-10-05
Granted: 2003-01-21
Abstract: A process is described for increasing the efficiency of para-xylene production using a two stage isomerization sequence. In the first stage of the process, a C9<SP>+</SP> aromatics feedstock is subjected to ethylbenzene conversion and xylene isomerization. Non-C8 aromatics are removed from the effluent, which is then processed in a second stage of the process to remove para-xylene and isomerize the para-xylene depleted effluent. The effluent from the second stage isomerization unit is then recycled into the inlet of the second stage of the process and a slip stream from the para-xylene separator is recycled to the feedstock and to the effluent of the ethylbenzene conversion unit. In this way, the production of para-xylene is maximized. In a preferred embodiment, toluene is co-fed into the feedstock to minimize the loss of xylenes during the ethylbenzene conversion reaction.
