Appl. No.:

10/193842

Inventors:

Robert Carrol Runyon - Sun City West AZ
Che Kiong Hor - Perak, MY

Assignee:

Keteca Singapore Singapore

International Classification:

H01L 2100

US Classification:

438 33, 438 68, 438113, 438114, 438115, 438458, 438462, 438476, 438612, 438976

Abstract:

The present invention teaches a sawn wafer with ultra clean bonding pads on die which enhance the strength of wire bond and results in higher yield and improved reliability of packaged semiconductor die. Clean wafers ready for dicing are coated with a removable insulating water soluble non-ionic film which enhances clean saw cuts and reduces buildup. The protective film is hardened by heat and resists removal by cooling water used in dicing saws. However, after dicing the protective film is removable in a wafer washer using high pressure warm D. I. water. After removal of the protective film the electrode pads are virtually as clean as before dicing. The film may be used as a protective layer until the sawn wafer is ready for use.

US Classification:

105 61, 105 50, 105 35, 104289

Abstract:

Designs for a battery-powered, all-electric locomotive and related locomotive and train configurations are provided. In one particular exemplary embodiment, a locomotive may be driven by a plurality of traction motors powered exclusively by a battery assembly which preferably comprises rechargeable batteries or other energy storage means. The locomotive carries no internal combustion engine on board and receives no power during operation from any power source external to the locomotive. A battery management system monitors and equalizes the batteries to maintain a desired state of charge (SOC) and depth of discharge (DOD) for each battery. A brake system may be configured to prioritize a regenerative braking mechanism over an air braking mechanism so that substantial brake energy can be recovered to recharge the battery assembly. Many locomotive or train configurations involving battery-powered or battery-toting locomotive(s) may be implemented. In one embodiment, a battery-toting locomotive is directly coupled with and positioned between two diesel-electric locomotives, wherein the batteries recover energy from regenerative braking and/or supply power to drive traction motors.

Appl. No.:

7/809887

Inventors:

Harold R. Klievoneit - Mesa AZ
Augustine G. Esposito - Phoenix AZ
Robert C. Runyon - Sun City West AZ

Assignee:

St. Florian Company - Phoenix AZ

International Classification:

B24B 100

US Classification:

51281SF

Abstract:

Apparatus and a method are disclosed for grinding opposed faces of the hub of a dicing blade flat and parallel while preserving the capability of electroplating the hub with a membrane. Apparatus and a method are also disclosed for obtaining a single or dual rectilinear or curvilinear radial taper of the dicing blade.

Appl. No.:

7/809310

Inventors:

Harold R. Klievoneit - Mesa AZ
Augustine G. Esposito - Phoenix AZ
Robert C. Runyon - Sun City West AZ

Assignee:

St. Florian Company

International Classification:

B24B 100

US Classification:

51295

Abstract:

A dicing blade is formed by plating a composition of diamond particles and silicon carbide whiskers suspended in a nickel solution upon an aluminum hub. To obtain bonding rather than capturing of the diamond particles, nickel coated diamond particles may be used to form an inter-metallic bond between the coated diamond particles, the silicon carbide whiskers and the nickel matrix.
