A component includes a plurality of electrical connections on a process side opposed to a back side of the component. Each electrical connection includes an electrically conductive multi-layer connection post protruding from the process side. A printed structure includes a destination substrate and one or more components. The destination substrate has two or more electrical contacts and each connection post is in contact with, extends into, or extends through an electrical contact of the destination substrate to electrically connect the electrical contacts to the connection posts. The connection posts or electrical contacts are deformed. Two or more connection posts can be electrically connected to a common electrical contact.

A semiconductor device includes a semiconductor substrate, a conductive pad on the semiconductor substrate, and a conductor over the conductive pad. The semiconductor device further has a polymeric material disposed over the semiconductor substrate and surrounding the conductor. The semiconductor device also includes an electric conductive layer between the conductor and the polymeric material. In the semiconductor device, an adhesion strength between the electric conductive layer and the polymeric material is greater than an adhesion strength between the polymeric material and the conductor.

A back plate and a manufacturing method thereof, a method for bonding a chip, and a display device are provided. The back plate includes: a base substrate; and, a plurality of conductive connecting tubes disposed on the base substrate, wherein one end of each of the conductive connecting tubes is connected to the base substrate, and a side wall of each of the conductive connecting tubes is provided with an opening penetrating the side wall. And, the method for bonding a chip includes: providing the back plate; inserting an electrode of the chip into a corresponding conductive connecting tube from an end of the conductive connecting tube away from the base substrate; and heating the conductive connecting tube and the chip, so that the electrode of the chip is electrically connected to the conductive connecting tube.
