Methods of forming wire and solder bonds are disclosed. In one embodiment, a method includes providing a structure including a wire bond metal region for the wire bond and a solder bond metal region for the solder bond, both regions covered by a silicon nitride layer over a silicon oxide layer; forming in a material a first opening to the silicon oxide layer over the wire bond metal region and a second opening exposing the solder bond metal region; forming the solder bond to the solder bond metal region while the wire bond metal region is covered; exposing the wire bond metal region including removing the silicon oxide layer to the wire bond metal region; and forming the wire bond to the wire bond metal region. Wire bonds and solder bonds can be made accessible on a single multi-part wafer (MPW) or on a single chip, if necessary, and can be formed substantially simultaneously.
