Patent ID: 8384411

Claim:
A device for measuring a signal of a die to be placed within a package, comprising: a semiconductor substrate on which at least one die is mounted, said semiconductor substrate having a measurement instrument embedded in said semiconductor substrate, at least one first conductive path for electrically connecting said die to said measurement instrument and at least one second conductive path for electrically connecting said measurement instrument to an electrode on a surface of said semiconductor substrate; a circuit board on which said semiconductor substrate is mounted so as to electrically connect the electrode of said semiconductor substrate to an electrode of said circuit board so that said measurement instrument is electrically connected to the electrode of said circuit board; and an interface port provided at said circuit board and electrically connected to the electrode of said circuit board; wherein a signal is transferred between said die and said interface port through said measurement instrument; and further comprising a cross point switch embedded in said semiconductor substrate for selectively connecting said first conductive paths to said embedded measurement instrument for applying a signal from said die to said embedded measurement instrument.
