Appl. No.:

7/891111

Inventors:

Paul D. Asetta - Mesa AZ
Rajiv Bajaj - Gilbert AZ
Lawrence R. Gardner - Chandler AZ
Michael P. Norman - Chandler AZ

Assignee:

Motorola, Inc. - Schaumburg IL

International Classification:

H01L 21302
H01L 21463

US Classification:

437225

Abstract:

A wax (13) dissolved in solvent is placed on a semiconductor wafer (12) and made uniform. An assembly is formed by bonding the semiconductor wafer (12) to a submount (17) with a uniform wax layer (14). The submount (17) supports and allows handling of the semiconductor wafer (12) during wafer process steps. The assembly is heated in a vacuum to remove solvent and air trapped in the uniform wax layer (14) thereby minimizing air voids which can cause a non-uniform bond. The assembly is then annealed to reduce stress on the semiconductor wafer (12) induced by differing material thermal expansion rates of the semiconductor wafer (12), the uniform wax layer (14), and the submount (17).

Abstract:

A full color light emitting diode display (310) utilizes semiconductor light emitting diodes (313) to produce red light and either organic or semiconductor light emitting diodes (312) to produce blue light. Green light is produced by either semiconductor light emitting diodes (313) or by organic light emitting diodes (343). An array of semiconductor light emitting diodes is formed on a semiconductor substrate (322) and an array of organic or semiconductor light emitting diodes is formed on an optically transparent substrate (311). The optically transparent and semiconductor substrates are attached together to form the multi-wavelength light emitting diode display (310).

International Classification:

H01L 3300

US Classification:

257 40

Abstract:

An integrated multicolor organic LED array formed by providing a negative layer and patterning a plurality of different color LED organic layers, one at a time, on the negative layer to form a plurality of different color LEDs in a plurality of areas of a selected array. A first color LED organic layer is patterned on the negative layer in first areas and to define additional areas for additional LEDs laterally separated from the first color LEDs and a final color LED organic layer is deposited in final areas and on previously patterned layers to form a plurality of final color LEDs. Transparent positive contacts are then formed on the final color LED layer in the first and final areas so as to form positive contacts to the first and the final color LEDs.

Abstract:

A semiconductor wafer (40) is placed in a first pressure chamber (37) of a bonding apparatus (10 or 60). A major surface (46) of a submount (44) is placed on a submount support (30 or 62). The major surface (46) of the submount (44) seals the first pressure chamber (37). A pressure differential is generated between the first pressure chamber (37) and a second pressure chamber (47) The pressure differential bows a central portion of the submount (44) toward the semiconductor wafer (40). The central portion of the submount (44) contacts an adhesive coating over a central portion of the semiconductor wafer (40). The submount support (30 or 62) is displaced to decrease a curvature on the submount (44). The pressure differential is increased to an end-point to facilitate bond formation between the semiconductor wafer (40) and the submount (44).
