Patent number: 10374159Abstract: A method for fabricating an optoelectronic device includes forming an adhesion layer on a substrate, forming a material layer on the adhesion layer and applying release tape to the material layer. The substrate is removed at the adhesion layer by mechanically yielding the adhesion layer. A conductive layer is applied to the material layer on a side opposite the release tape to form a transfer substrate. The transfer substrate is transferred to a target substrate to join the target substrate to the conductive layer of the transfer substrate. The release tape is removed from the material layer to form a top emission optoelectronic device.Type: GrantFiled: September 29, 2016Date of Patent: August 6, 2019Assignee: International Business Machines CorporationInventors: Jeehwan Kim, Ning Li, Devendra K. Sadana, Tze-bin Song

Patent number: 9337436Abstract: A method for fabricating a photovoltaic device includes forming an adhesion layer on a substrate, forming a material layer on the adhesion layer and applying release tape to the material layer. The substrate is removed at a weakest interface between the adhesion layer and the substrate by mechanically pulling the release tape to form a transfer substrate including the adhesion layer, the material layer and the release tape. The transfer substrate is transferred to a target substrate to contact the adhesion layer to the target substrate. The transfer substrate includes a material sensitive to formation processes of the transfer substrate such that exposure to the formation processes of the transfer substrate is avoided by the target substrate.Type: GrantFiled: June 11, 2015Date of Patent: May 10, 2016Assignee: GLOBALFOUNDRIES INC.Inventors: Keith E. Fogel, Jeehwan Kim, Devendra K. Sadana, Tze-bin Song
