    Abstract: 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.

    Abstract translation: 本发明提供了能够构造形成在可以被微转印印刷的蓝宝石衬底上的微型LED小芯片的结构和方法。 这种印刷结构使得低成本,高性能的电连接微型LED阵列可用于例如显示系统。 此外,在一个实施例中,用于印刷的LED的电触点在单组工艺步骤中电互连。 在某些实施例中,可印刷的微器件的形成开始于半导体结构保留在衬底上。 在部分地形成可印刷的微器件之后,将手柄衬底附接到与衬底相对的系统,使得系统固定到手柄衬底。 然后可以去除衬底并完成半导体结构的形成。 完成后,可打印的微型装置可以是微转印印刷到目的基板。

    Abstract: A repaired transfer printed system (e.g., micro-transfer printed system) includes a system substrate having two or more contact pads disposed on the system substrate. One or more transfer printed devices (e.g., micro-transfer printed devices) are disposed in contact with the system substrate, each device having two or more connection posts. Each connection post of a replacement device is in physical contact with a contact pad, the connection post forming a second imprint in the physically contacted contact pad. In certain embodiments, a first imprint is in at least one of the physically contacted contact pads and is between the replacement device and the system substrate.
