Patent number: 11469259Abstract: Methods of forming integrated circuit devices include forming a sacrificial layer on a handling substrate and forming a semiconductor active layer on the sacrificial layer. The semiconductor active layer and the sacrificial layer may be selectively etched in sequence to define an semiconductor-on-insulator (SOI) substrate, which includes a first portion of the semiconductor active layer. A multi-layer electrical interconnect network may be formed on the SOI substrate. This multi-layer electrical interconnect network may be encapsulated by an inorganic capping layer that contacts an upper surface of the first portion of the semiconductor active layer. The capping layer and the first portion of the semiconductor active layer may be selectively etched to thereby expose the sacrificial layer.Type: GrantFiled: February 4, 2021Date of Patent: October 11, 2022Assignee: X Display Company Technology LimitedInventors: Christopher Bower, Etienne Menard, Matthew Meitl, Joseph Carr

Patent number: 11456258Abstract: The present invention provides stretchable, and optionally printable, semiconductors and electronic circuits capable of providing good performance when stretched, compressed, flexed or otherwise deformed. Stretchable semiconductors and electronic circuits of the present invention preferred for some applications are flexible, in addition to being stretchable, and thus are capable of significant elongation, flexing, bending or other deformation along one or more axes. Further, stretchable semiconductors and electronic circuits of the present invention may be adapted to a wide range of device configurations to provide fully flexible electronic and optoelectronic devices.Type: GrantFiled: February 11, 2019Date of Patent: September 27, 2022Assignee: The Board of Trustees of the University of IllinoisInventors: John A. Rogers, Dahl-Young Khang, Yugang Sun, Etienne Menard

Patent number: 10717267Abstract: In a method of printing a transferable component, a stamp including an elastomeric post having three-dimensional relief features protruding from a surface thereof is pressed against a component on a donor substrate with a first pressure that is sufficient to mechanically deform the relief features and a region of the post between the relief features to contact the component over a first contact area. The stamp is retracted from the donor substrate such that the component is adhered to the stamp. The stamp including the component adhered thereto is pressed against a receiving substrate with a second pressure that is less than the first pressure to contact the component over a second contact area that is smaller than the first contact area. The stamp is then retracted from the receiving substrate to delaminate the component from the stamp and print the component onto the receiving substrate. Related apparatus and stamps are also discussed.Type: GrantFiled: June 28, 2016Date of Patent: July 21, 2020Inventors: Etienne Menard, John A. Rogers, Seok Kim, Andrew Carlson

Patent number: 10416425Abstract: CPV modules include a back plate having an array of 1 mm2 or smaller solar cells thereon. A backplane interconnect network is also provided on the back plate. This backplane interconnect network operates to electrically connect the array of solar cells together. A front plate, which is spaced-apart from the back plate, is provided. This front plate includes an array of primary lenses thereon that face the array of solar cells. The front plate can be configured to provide a greater than 1000× lens-to-cell light concentration to the array of solar cells. To achieve this 1000× lens-to-cell light concentration, the primary lenses can be configured as plano-convex lenses having a lens sag of less than about 4 mm. An array of secondary optical elements may also be provided, which extend between the array of primary lenses and the array of solar cells.Type: GrantFiled: February 9, 2010Date of Patent: September 17, 2019Assignee: X-Celeprint LimitedInventors: Etienne Menard, Christopher Bower, Scott Burroughs, Joe Carr, Bob Conner, Sergiy Dets, Bruce Furman, Matthew Meitl, Michael Sullivan -
