Techniques are disclosed for forming a frame on the backplane comprising structures at least partially circumscribing or enclosing metal contacts on the backplane. In some embodiments, the frame may comprise a photoresist. The dimensions and structural integrity of the frame can help prevent misalignment and/or damage of physical obtrusions of light-emitting structures during a bonding process of the light-emitting structures to the backplane.

A first conductive pad is connected to a second conductive pad by using a post-transition metal and a nanoporous metal. An example of the post-transition metal is indium. An example of the nanoporous metal is nanoporous gold. A block of the post-transition metal is formed on the first conductive pad. The block of the post-transition metal is coated with a layer of anti-corrosion material. A block of the nanoporous metal is formed on the second conductive pad. The block of the post-transition metal and the block of the nanoporous metal are thermal compressed to form an alloy between the first conductive pad and the second conductive pad.
