Abstract
Raised electrical contacts are electroplated on selected previously metallized contacts of a semiconductor device. Each metallized contact is on a surface of a separate mesa, respectively, of the device and extends in a cantilever manner beyond the surface of the mesa. The electroplating of the raised electrical contacts is accomplished by the steps of (1) depositing a layer of a metal over the device, (2) applying a photoresist over the layer of the metal, (3) defining openings in the photoresist over areas of the metallized contacts where the raised contacts are to be formed, and (4) electroplating the raised contacts on the metallized contacts through the openings, using the layer of the metal as an electrode in an electroplating system.
