US Patent:

6395636, May 28, 2002

Filed:

Jan 9, 2001

Appl. No.:

09/757879

Inventors:

Eric Ian Hanson - Maple Grove MN

Assignee:

Honeywell International Inc. - Morristown NJ

International Classification:

H01L 21302

US Classification:

438692, 438697

Abstract:

The present invention provides a method for improving the planarization of a top layer deposited over a patterned layer on a semiconductor wafer. The patterned layer may include both small and large features. Openings, grooves, or trenches are etched partially or completely through certain larger target features in the patterned layer in an effort to mimic the topography of areas where the patterned layer includes smaller features. Subsequent deposition of the top layer may result in a more consistent or regular topography across the surface of the top layer. Accordingly, high areas on the top layer that contact a polishing pad of a CMP system will tend to be removed at a similar rate since the pressure exerted by each of the high areas will be similar.

International Classification:

H01M 600

US Classification:

296231, 429209, 42923195, 429233

Abstract:

An apparatus and method for treating a cathode material provided on a surface of a continuous thin-film substrate and a treated thin-film cathode having increased smoothness are disclosed. A web of untreated cathode material is moved between a feed mechanism and a take-up mechanism, and passed through a treatment station. The web of cathode material typically includes areas having surface defects, such as prominences extending from the surface of the cathode material. The surface of the cathode material is treated with an abrasive material to reduce the height of the prominences so as to increase an 85 degree gloss value of the cathode material surface by at least approximately 10. The web of cathode material may be subjected to a subsequent abrasive treatment at the same or other treatment station. Burnishing or lapping film is employed at a treatment station to process the cathode material. An abrasive roller may alternatively be used to process the web of cathode material.

US Classification:

270 5209, 221 73, 156230, 156361, 156540, 156541, 156584, 156542

Abstract:

A product stacking apparatus and method employs one or more stations, each including a stationary stacking platform or a conveyor upon which spaced-apart pucks are coupled for travel thereon. A product delivery apparatus drives one or more movable webs to which segmented product sheets are removably affixed. The product delivery apparatus includes one or more rotatable lamination interfaces associated with each of the stations for transferring product sheets from the webs to the pucks on a repetitive basis to produce a stack of product sheets on the respective pucks. Each of the segmented product sheets may define all or a portion of an electrochemical cell, all or a portion of a pad including layers of film or sheet material, wherein a portion of each of the layers is provided with a bonding feature, or all or a portion of a pack comprising layers of medical dressing. A puck need not be in motion during the transfer of the product sheet from the lamination roll to the puck. The puck may or may not be attached to a conveyor, but the conveyor need not be in motion during the lamination or stack building process.

US Classification:

156264, 156269, 156517, 156519, 156522, 296233, 296234

Abstract:

An apparatus and method provides for rotatably cutting and/or laminating layered structures or sheet material supported by webs. A rotary converting apparatus and method of the present invention converts a web comprising a cathode layered structure and a web comprising an anode layered structure into a series of layered electrochemical cell structures supported by a release liner. Employment of a rotary converting process of the present invention provides, among other benefits, for the creation of a product having a finished size, without need for downstream or subsequent cutting.
