Classification: H01L

Abstract:
A method for producing an emulation circuit configuration from an integrated circuit, which comprises:providing a first integrated circuit including a first wiring layer having conductor tracks with widened portions functioning as contacts; applying a further wiring layer having conductor tracks to the first integrated circuit; connecting the conductor tracks of the further wiring layer to the widened portions of the first wiring layer; providing contact faces on the conductor tracks of the further wiring layer for allowing access to additional output signals provided in addition to regular output signals of the first integrated circuit; connecting the contact faces of the further wiring layer to external chip connections; placing a second integrated circuit having input signal terminals and contact faces above the further wiring layer; electrically conductively connecting the input signal terminals of the second integrated circuit to the contact faces of the further wiring layer of the first integrated circuit; connecting the contact faces of the further wiring layer of the first integrated circuit to a terminal for a supply potential via the conductor tracks each having a portion with a reduced cross-sectional area; and subsequently severing the portion with the reduced cross-sectional area of the conductor tracks with a current pulse impressed via the second integrated circuit.
