Title: Integrated deethanizer and ethylene fractionation column and process for separating a feed stream
Inventor: STORK KARL
IPC: B01D1/28
Filed: 2000-03-10
Granted: 2002-10-21
Abstract: An integrated deethanizer and ethylene fractionation column and process for separating a feed stream comprising ethylene, ethane and C3+ is disclosed. A single shell houses a refluxed upper portion and a lower portion of the column. A generally vertical wall partitions the lower portion of the column into a deethanizer section and an ethylene stripper section. The upper column portion is used as the absorption section of the ethylene fractionator. The feed is supplied to an intermediate stage in the deethanizer, and the deethanizer is operated at a lower pressure (and correspondingly lower temperature) matching that of the ethylene fractionation. The design allows the use of one slightly larger column in place of the two large columns previously used for separate deethanization and ethylene fractionation.

Title: A super-self-aligned trench gate DMOS with reduced on-resistance
Inventor: WILLIAMS RICHARD K
IPC: H01L29/10
Filed: 2000-04-21
Granted: 2002-07-11
Abstract: A novel super-self-aligned (SSA) structure and manufacturing process uses a single photomasking layer to define critical features and dimensions of a trench-gated vertical power DMOSFET. The single critical mask determines the trench surface dimension, the silicon source-body mesa width between trenches, and the dimensions and location of the silicon mesa contact. The contact is self-aligned to the trench, eliminating the limitation imposed by contact-to-trench mask alignment in conventional trench DMOS devices needed to avoid process-induced gate-to-source shorts. Oxide step height above the silicon surface is also reduced avoiding metal step coverage problems. Poly gate bus step height is also reduced. Other features described include polysilicon diode formation, controlling the location of drain-body diode breakdown, reducing gate-to-drain overlap capacitance, and utilizing low-thermal budget processing techniques.

Title: System and method for aligning optical fiber collimators
Inventor: FRANCIS KURT RICHARD
IPC: G02B6/34
Filed: 2000-08-05
Granted: 2002-09-01
Abstract: A method and apparatus of aligning a collimator assembly requiring only single-axis adjustment and for which the collimator may be paired with any other similarly aligned collimator. A collimator typically includes a fiber grasped by a ferrule. Both the ferrule and a graded-index (GRIN) lens are eventually bonded to the inside of a glass tube with the fiber/lens distance fixed for optimum collimator performance. According to one method of practicing the invention, the tube/lens assembly is fixed, and the ferrule/fiber is slidably inserted into the tube. The position of the ferrule/fiber is adjusted within the tube while the size of the resultant beam is measured at a fixed distance from the output from the lens. If there are two such position producing the optimum beam size, the position of less separation between the ferrule and fiber is chosen. The collimators aligned by the invention may be freely paired with each other (for example, within a sleeve or housing also containing an optical element located between the two collimators). An optimum beam size and optimum measuring distance may be established by an optical calculation or other optimization technique dictate for the intended use of the collimator.

Title: Method for contact size control for NAND technology
Inventor: WANG JOHN JIANSHI
IPC: H01L23/522
Filed: 2000-08-18
Granted: 2001-10-01
Abstract: The present invention provides a method for providing an interconnect in a flash memory device. A first embodiment includes forming at least one contact hole in a peripheral area of the device; bombarding a bottom of the at least one contact hole with ions, where the ions break down undesired oxide residing at the bottom of the at least one contact hole; depositing a barrier metal layer into the at least one contact hole, where the barrier metal layer breaks down remaining undesired oxide at the bottom of the at least one contact hole, and where bombarding with the ions and the depositing of the barrier metal layer minimize an undesired widening of the at least one contact hole; and depositing a contact material into the at least one contact hole. With the first embodiment, both the ions and the titanium break down the undesired oxide while neither breaks down the desired oxide at the sides of the contact hole to a significant degree. Thus, the undesired oxide at the bottom of the contact hole is removed while the enlargement of the contact hole is minimized. A second embodiment of the method, a contact hole having tapered sides with a top being wider than a bottom is used, where the tapered sides minimizes chances of inadvertently etching any field oxide adjacent to the contact hole. In a third embodiment of the method, the first and second embodiments are combined, minimizing the enlargement of the contact hole and the chances of inadvertently etching the field oxide simultaneously. The reliability of the device is thus increased.
