Abstract:
A process of bumping a die backside includes opening a recess in a die backside film (DBF) to expose a through-silicon via (TSV) contact in a die, followed by filling the recess with a conductive material that contacts the TSV contact. Added solder is coupled to the conductive material at a level of the DBF.A subsequent die is coupled to the first die at the added solder to form an electrical coupling consisting of the TSV contact, the conductive material, and the added solder, an electrical bump coupled to the subsequent die. Apparatus and computer systems are assembled using the process.
