Selective micro device transfer to receiver substrate
11735547 · 2023-08-22 · ·

A method of selectively transferring micro devices from a donor substrate to contact pads on a receiver substrate. Micro devices being attached to a donor substrate with a donor force. The donor substrate and receiver substrate are aligned and brought together so that selected micro devices meet corresponding contact pads. A receiver force is generated to hold selected micro devices to the contact pads on the receiver substrate. The donor force is weakened and the substrates are moved apart leaving selected micro devices on the receiver substrate. Several methods of generating the receiver force are disclosed, including adhesive, mechanical and electrostatic techniques.

Package Structure and Method and Equipment for Forming the Same

An apparatus for manufacturing packaged semiconductor devices includes a lower plate having package platforms and clamp guide pins to align an upper plate with the lower plate, and a boat tray having windows configured to receive package devices, and a plurality of upper plates configured to be aligned to respective windows and respective package platforms. Clamping force can be applied by fasteners configured to generate a downward force upon the upper plate. Package devices on the platforms are thus subjected to a clamping force. Load cells measure the clamping force so adjustments can be made.
