Publication number: 20020172887Abstract: A thermal transfer element for forming a multilayer device may include a substrate and a multicomponent transfer unit that, when transferred to a receptor, is configured and arranged to form a first operational layer and a second operational layer of a multilayer device. In at least some instances, the thermal transfer element also includes a light-to-heat conversion (LTHC) layer that can convert light energy to heat energy to transfer the multicomponent transfer unit. Transferring the multicomponent transfer unit to the receptor may include contacting a receptor with a thermal transfer element having a substrate and a multicomponent transfer unit. Then, the thermal transfer element is selectively heated to transfer the multicomponent transfer unit to the receptor according to a pattern to form at least first and second operational layers of a device.Type: ApplicationFiled: May 2, 2002Publication date: November 21, 2002Applicant: 3M Innovative Properties CompanyInventors: Martin B. Wolk, Paul F. Baude, Jeffrey M. Florczak, Fred B. McCormick, Yong Hsu

Patent number: 6410201Abstract: Disclosed are thermal transfer elements and processes for patterning solvent-coated layers and solvent-susceptible layers onto the same receptor substrate. These donor elements and methods are particularly suited for making organic electroluminescent devices and displays. The donor elements can include a substrate, an optional light-to-heat conversion layer, and a single or multicomponent transfer layer that can be imagewise transferred to a receptor to form an organic electroluminescent device, portions thereof, or components therefor. The methods offer advantages over conventional patterning techniques such as photolithography, and make it possible to fabricate new organic electroluminescent device constructions.Type: GrantFiled: July 24, 2001Date of Patent: June 25, 2002Assignee: 3M Innovative Properties CompanyInventors: Martin B.

Patent number: 6399258Abstract: Patterned articles, such as RFID antenna, are made by subablation, a process comprising the steps of: A. providing a substrate having a coating, such as a metal or metal oxide, and an interface comprising the thin region where the coating and the substrate are closest to each other; B. exposing at least one part of the total area of the coating to a flux of electromagnetic energy, Such as a focused excimer laser beam, sufficient to disrupt the interface but insufficient to ablate the coating, and C. removing the parts of the coating in registry with the portion of the interface area that was disrupted, by means such as ultrasonic agitation. The process has advantages over photo-resist processes in that there is no residual chemical resist left on the product and no undercutting of the pattern or image. It has advantages over laser ablation processes in that higher throughput is possible at the same energy level and there is no microscopic debris left on the product surface.Type: GrantFiled: January 12, 2001Date of Patent: June 4, 2002Assignee: 3M Innovative Properties CompanyInventors: Dennis P. O'Brien, Jeffrey M. Florczak, Robert L. W. Smithson

Patent number: 5640382Abstract: A dual layer pre-recorded optical disc includes a transparent substrate, a partially reflective layer, a transparent spacer layer, and a highly reflective layer. One pattern of data pits is provided on the substrate, adjacent the partially reflective layer, and another pattern of data pits is provided on the spacer layer, adjacent the highly reflective layer. The partially reflective layer may be made of an alloy of gold and silver having a general formula Au.sub.x Ag.sub.y, where 15<x<40 and 60<y<85. A substrate-incident beam can be used to read data encoded in either data pit pattern depending on which layer the laser is focused upon. The dual layer disc has twice the data storage capacity of conventional single layer discs.Type: GrantFiled: December 19, 1995Date of Patent: June 17, 1997Assignee: Imation Corp.Inventors: Jeffrey M.
