摘要： A manufacturing method of a metal bump structure is provided. A driving base is provided. At least one pad and an insulating layer are formed on the driving base. The pad is formed on an arrangement surface of the driving base and has an upper surface. The insulating layer covers the arrangement surface of the driving base and the pad, and exposes a part of the upper surface of the pad. A patterned metal layer is formed on the upper surface of the pad exposed by the insulating layer, and extends to cover a part of the insulating layer. An electro-less plating process is performed to form at least one metal bump on the patterned metal layer. A first extension direction of the metal bump is perpendicular to a second extension direction of the driving base.

摘要： A flat panel substrate with integrated antennas and wireless power transmission system for delivering power to a receiving device is presented herein. A method can comprise depositing, onto a flat panel substrate, an antenna layer comprising multiple adaptively phased antennas elements; and depositing, onto the flat panel substrate, respective thin film transistor (TFT)-based antenna management circuits for the multiple adaptively phased antenna elements—the respective TFT-based antenna management circuits being operable to measure respective first phases at which first signals are received at the multiple adaptively phased antenna elements, and based on the respective first phases, control respective second phases at which second signals are transmitted from the multiple adaptively phased antenna elements to facilitate delivery, via the second signals, of power to the receiving device. Further, the method comprises forming traces communicatively coupling the multiple adaptively phased antenna elements to the respective TFT-based antenna management circuits.

摘要： Provided is a thin film transistor including a highly-textured dielectric layer, an active layer, a gate electrode and a source/drain electrode that are stacked on a base substrate. The source/drain electrode includes a source electrode and a drain electrode. The gate electrode and the active layer are insulated from each other. The source electrode and the drain electrode are electrically connected to the active layer. Constituent particles of the active layer are of monocrystalline silicon-like structures. According to the present disclosure, the highly-textured dielectric layer is adopted to replace an original buffer layer to induce the active layer to grow into a monocrystalline silicon-like structure, such that the performance of the thin film transistor is improved.
