Abstract: Mass transfer of micro structures are effected from one substrate to another using adhesives. In the context of an integrated micro LED display, a micro LED array is fabricated on a native substrate and corresponding CMOS pixel drivers are fabricated on a separate substrate. The micro LED substrate (e.g., sapphire) and the CMOS substrate (e.g., silicon) may be incompatible. For example, they may have different thermal coefficients of expansion which make it difficult to bond the micro LEDs to the pixel driver circuitry. The micro LED array is transferred to an intermediate substrate (e.g., silicon) by use of an adhesive. This intermediate substrate may be used in a process of bonding the micro LED array to the array of pixel drivers. The intermediate substrate is separated from the micro LED array by releasing the adhesive.

Abstract: The present application relates to a turn-off power semiconductor device having a wafer with an active region and a termination region surrounding the active region, a rubber ring as an edge passivation for the wafer and a gate ring placed on a ring-shaped gate contact on the termination region for contacting the gate electrodes of a thyristor cell formed in the active region of the wafer. In the turn-off power semiconductor device, the outer circumferential surface of the gate ring is in contact with the rubber ring to define the inner border of the rubber ring. The area consumed by the ring-shaped gate contact on the termination or edge region can be minimized. The upper surface of the gate ring and the upper surface of the rubber ring form a continuous surface extending in a plane parallel to the first main side of the wafer.
