Patent number: 10475876Abstract: A single metal layer device, such as a display or sensor, comprises a substrate and a patterned metal layer. The patterned metal layer forms a two-dimensional array of spatially separated column line segments that each extend only partially across the display substrate in a column direction and forms a one-dimensional array of row lines extending across the display substrate in a row direction different from the column direction. The row lines and column line segments are electrically separate in the patterned metal layer. Spatially separated electrical jumpers are disposed on the display substrate and electrically connect pairs of column line segments adjacent in the column direction. Each electrical jumper has an independent jumper substrate independent of and separate from the display substrate. In certain embodiments, spatially separated light-emitting pixel circuits are disposed on a display substrate and are electrically connected to at least one row line and one column line.Type: GrantFiled: July 25, 2017Date of Patent: November 12, 2019Assignee: X-Celeprint LimitedInventors: Christopher Bower, Matthew Meitl, Carl Prevatte, Ronald S.

Patent number: 10468363Abstract: A component includes a plurality of electrical connections on a process side opposed to a back side of the component. Each electrical connection includes an electrically conductive multi-layer connection post protruding from the process side. A printed structure includes a destination substrate and one or more components. The destination substrate has two or more electrical contacts and each connection post is in contact with, extends into, or extends through an electrical contact of the destination substrate to electrically connect the electrical contacts to the connection posts. The connection posts or electrical contacts are deformed. Two or more connection posts can be electrically connected to a common electrical contact.Type: GrantFiled: August 10, 2015Date of Patent: November 5, 2019Assignee: X-Celeprint LimitedInventors: Carl Prevatte, Christopher Bower, Ronald S.

Publication number: 20190326470Abstract: The present invention provides structures and methods that enable the construction of micro-LED chiplets formed on a sapphire substrate that can be micro-transfer printed. Such printed structures enable low-cost, high-performance arrays of electrically connected micro-LEDs useful, for example, in display systems. Furthermore, in an embodiment, the electrical contacts for printed LEDs are electrically interconnected in a single set of process steps. In certain embodiments, formation of the printable micro devices begins while the semiconductor structure remains on a substrate. After partially forming the printable micro devices, a handle substrate is attached to the system opposite the substrate such that the system is secured to the handle substrate. The substrate may then be removed and formation of the semiconductor structures is completed. Upon completion, the printable micro devices may be micro transfer printed to a destination substrate.Type: ApplicationFiled: July 3, 2019Publication date: October 24, 2019Inventors: Christopher Bower, Matthew Meitl, David Gomez, Carl Prevatte, Salvatore Bonafede

Publication number: 20190326149Abstract: In certain embodiments, a method of making a semiconductor structure suitable for transfer printing (e.g., micro-transfer printing) includes providing a support substrate and disposing and processing one or more semiconductor layers on the support substrate to make a completed semiconductor device. A patterned release layer and, optionally, a capping layer are disposed on or over the completed semiconductor device and the patterned release layer or capping layer, if present, are bonded to a handle substrate with a bonding layer. The support substrate is removed to expose the completed semiconductor device and, in some embodiments, a portion of the patterned release layer. In some embodiments, an entry path is formed to expose a portion of the patterned release layer. In some embodiments, the release layer is etched and the completed semiconductor devices transfer printed (e.g., micro-transfer printed) from the handle substrate to a destination substrate.Type: ApplicationFiled: July 3, 2019Publication date: October 24, 2019Inventors: Christopher Bower, Matthew Meitl, António José Marques Trindade, Ronald S.

Patent number: 10446719Abstract: The disclosed technology provides micro-assembled micro-LED displays and lighting elements using arrays of micro-LEDs that are too small (e.g., micro-LEDs with a width or diameter of 10 ?m to 50 ?m), numerous, or fragile to assemble by conventional means. The disclosed technology provides for micro-LED displays and lighting elements assembled using micro-transfer printing technology. The micro-LEDs can be prepared on a native substrate and printed to a display substrate (e.g., plastic, metal, glass, or other materials), thereby obviating the manufacture of the micro-LEDs on the display substrate. In certain embodiments, the display substrate is transparent and/or flexible.Type: GrantFiled: June 18, 2015Date of Patent: October 15, 2019Assignee: X-Celeprint LimitedInventors: Christopher Bower, Matthew Meitl, David Gomez, Salvatore Bonafede, David Kneeburg, Alin Fecioru, Carl Prevatte
