Patent ID: 7026829

Claim:
A method for de-embedding a device under test having N terminals, N being an integer larger than one, the device under test having device specific microwave characteristics and being embedded in a semiconductor article of manufacture by a DUT embedding structure, the semiconductor article of manufacture being embedded in a measurement network, the method comprising the steps of: measuring DUT network parameter values of the device under test; measuring open network parameter values of an open device having N terminals, which are mutually electrically insulated, the open device being embedded in a semiconductor article of manufacture by an embedding structure, which is substantially identical to the DUT embedding structure; measuring short network parameter values of a short device having N terminals, which are mutually electrically connected by conductors, each conductor having a short device DC resistance, the short device being embedded in a semiconductor article of manufacture by an embedding structure, which is substantially identical to the DUT embedding structure; measuring load network parameter values of a load device having N terminals, which are mutually electrically connected by resistors, each resistor having a load device DC resistance, which is larger than the short device DC resistance, the load device being embedded in a semiconductor article of manufacture by an embedding structure, which is substantially identical to the DUT embedding structure, the load device having a parasitic load impedance, and determining the device specific microwave characteristics, in that the method further comprises the step of determining the parasitic load impedance prior to the step of determining the device specific microwave characteristics.
