Abstract

Apparatus for making electrical interconnection of semiconductor die includes a transfer carrier having an electrically conductive material arranged in a pattern on a transfer surface. A transfer process for electrical interconnect includes steps of aligning the transfer apparatus with an edge of a die to be interconnected; and moving the transfer apparatus toward the die edge (or moving the die edge toward the transfer apparatus, or moving both the transfer carrier and the die edge in relation to one another) to bring the patterned conductive material on the transfer surface and interconnect terminals on the die into contact. In some embodiments the carrier is left in place in a functioning interconnected device; in other embodiments the transfer carrier and the die edge are separated to leave at least a portion of the conductive material in contact with the interconnect terminals.
