Appl. No.:

09/745266

Inventors:

Fan Zhang - San Jose CA
Daniel L. Towery - Santa Clara CA
Joseph A. Levert - Santa Clara CA
Shyama P. Mukherjee - Morgan Hill CA

Assignee:

Honeywell International Inc. - Morristown NJ

International Classification:

C11D 708

US Classification:

510175, 252 794, 438693

Abstract:

Chemical mechanical planarization or spin etch planarization of surfaces of copper, tantalum and tantalum nitride is accomplished by means of the chemical formulations of the present invention. The chemical formulations may optionally include abrasive particles and which may be chemically reactive or inert. Contact or non-contact CMP may be performed with the present chemical formulations. Substantially 1:1 removal rate selectivity for Cu and Ta/TaN is achieved.

International Classification:

C09K 1300

US Classification:

252 791

Abstract:

The present invention relates to apparatus, procedures and compositions for avoiding and reducing damage to low dielectric constant materials and other soft materials, such as Cu and Al, used in fabricating semiconductor devices. Damage reduction can be achieved by decreasing the role of mechanical abrasion in the CMP of these materials and increasing the role of chemical polishing, which can also improve material removal rates. Increasing the role of chemical polishing can be accomplished by creating a polishing slurry, which contains components that interact chemically with the surface to be polished. This slurry may or may not also contain soft abrasive particles, which replace the hard abrasive particles of conventional slurries. Use of soft abrasive particles can reduce the role of mechanical abrasion in the CMP process. Use of this slurry in CMP can reduce surface scratches and device damage.

Abstract:

An apparatus comprising a memory, a plurality of modules, an address translation unit and a controller. The memory may be arranged as a plurality of memory banks. Each of the plurality of modules may be configured to generate one or more addresses for accessing a particular one of the plurality of memory banks. The address translation unit may be configured to modify the one or more addresses in response to a control signal. The controller may be configured to generate the control signal in response to a computer executable instruction.

Abstract:

An adaptive controller generates a sequence of dither signals for each of a plurality of control parameters. Each dither signal sequence is uncorrelated with every other dither signal sequence. Each nominal control signal has the first of its respective dither signal values simultaneously summed with it to form the control parameter values used by the controller. Updated control signals are applied in parallel to the controller outputs and a performance measure is taken and stored. The second signals in the dither control sequences are then summed with their respective nominal controls and applied in parallel to the controller and a second performance measure is taken and stored. This process is repeated for the length of the dither control signal sequence to yield a sequence of performance measurements. The sequence of performance measurements is correlated with each of the dither sequences, forming sequences of correlator outputs, one for each control signal. Each correlator output sequence is integrated and, depending upon the value of a correlator's integration output, the corresponding nominal signal has it's dither value added to or subtracted from it to form the respective, updated control values.

International Classification:

A61B 17/08

US Classification:

606153, 606151

Abstract:

Described here are devices and methods for intussuscepting a portion of stomach tissue. Typically the intussusception is created at a position near, but distal to the gastroesophageal junction, and a pouch capable of storing a volume (from about 0 cc up to about 100 cc) is created proximal the intussuscepted tissue. In this way, the amount of food that may be ingested is reduced, helping to ameliorate GERD symptoms, and aiding in weight loss efforts. Some of the devices described here include an expandable member and at least one suction inlet. In these devices, the expandable member is expanded to create a proximal cavity into which the stomach tissue is pulled (e. g. , using suction), thereby creating the intussusception.
