An electronic module on a flexible planar circuit substrate with a conductor configuration on a first substrate surface and a plurality of electronic components on the opposite, second substrate surface, wherein the components have component contacts, which are electrically connected selectively by way of vias in the circuit substrate and the conductor configuration, wherein the circuit substrate is a thermoplastic polymer and the component contacts are melted or thermally pressed into the second substrate surface in the region of the vias.

An apparatus includes a transfer mechanism to transfer an electrically-actuatable element directly from a wafer tape to a transfer location on a circuit trace on a product substrate. The transfer mechanism includes one or more transfer wires. Two or more stabilizers disposed on either side of the one or more transfer wires. A needle actuator is connected to the one or more transfer wires and the two or more stabilizers to move the one or more transfer wires and the two or more stabilizers to a die transfer position.

An electronic device includes a substrate, a first conductive pad and a chip. The first conductive pad is disposed on the substrate. The chip includes a second conductive pad electrically connected to the first conductive pad, and the first conductive pad is disposed between the substrate and the second conductive pad. The first conductive pad has a first groove.

Post-processing steps for integrating of micro devices into system (receiver) substrate or improving the performance of the micro devices after transfer. Post processing steps for additional structures such as reflective layers, fillers, black matrix or other layers may be used to improve the out coupling or confining of the generated LED light. Dielectric and metallic layers may be used to integrate an electro-optical thin film device into the system substrate with transferred micro devices. Color conversion layers may be integrated into the system substrate to create different outputs from the micro devices.

The present disclosure relates to a method of manufacturing a first electronic circuit including a planar surface, intended to be affixed to a second electronic circuit by a self-assembly method with a hybrid molecular bonding, and first electrically-conductive pads exposed on the surface. The method includes the forming of a peripheral area around the surface including second exposed and raised pads, each at least partly having the same composition as the first pads.

A method for executing a direct transfer of semiconductor device die from a first substrate to transfer locations on a second substrate. The method includes determining a position of impact wires disposed on a transfer head, semiconductor device die, and transfer locations; determining whether there are at least two positions that an impact wire, a semiconductor device die, and a transfer locations are aligned within a threshold tolerance; and transferring, by the impact wires, the semiconductor device die such that the semiconductor device die detaches from the first substrate and attaches to transfer locations on the second substrate. The transferring being completed based at least in part on determining that the impact wire, the semiconductor device die, and the circuit trace are aligned within the threshold tolerance.

Representative implementations of techniques and devices are used to remedy or mitigate the effects of damaged interconnect pads of bonded substrates. A recess of predetermined size and shape is formed in the surface of a second substrate of the bonded substrates, at a location that is aligned with the damaged interconnect pad on the first substrate. The recess encloses the damage or surface variance of the pad, when the first and second substrates are bonded.
