This invention relates to the process of correcting misalignment and filling voids after a microdevice transfer process. The process involves transfer heads, measurement of offset and misalignment in horizontal, vertical, and rotational errors. An execution of the new offset vector for the next transfer corrects the alignment.

A method of integrating a first substrate having a first surface with a first insulating material and a first contact structure with a second substrate having a second surface with a second insulating material and a second contact structure. The first insulating material is directly bonded to the second insulating material. A portion of the first substrate is removed to leave a remaining portion.
