Patent number: 9293622Abstract: Re-emitting semiconductor constructions (RSCs) for use with LEDs, and related devices, systems, and methods are disclosed. A method of fabrication includes providing a semiconductor substrate, forming on a first side of the substrate a semiconductor layer stack, attaching a carrier window to the stack, and removing the substrate after the attaching step. The stack includes an active region adapted to convert light at a first wavelength ?1 to visible light at a second wavelength ?2, the active region including at least a first potential well. The attaching step is carried out such that the stack is disposed between the substrate and the carrier window, which is transparent to the second wavelength ?2. The carrier window may also have a lateral dimension greater than that of the stack. The removal step is carried out so as to provide an RSC carrier device that includes the carrier window and the stack.Type: GrantFiled: May 3, 2010Date of Patent: March 22, 2016Assignee: 3M Innovative Properties CompanyInventors: Terry L. Smith, Catherine A. Leatherdale, Michael A. Haase, Thomas J. Miller, Xiaoguang Sun, Zhaohui Yang, Todd A. Ballen, Amy S. Barnes
