Abstract A testing contactor is provided for testing small-size semiconductor devices with large currents at high frequencies. Each semiconductor device to be tested has a plurality of leads. The testing contactor includes a plurality of first electric contact elements. A first Kelvin contact for a lead is formed of a first electric contact element in contact with the lead. The testing contactor further includes a plurality of second electric contact elements and a plurality of electric connection elements. An electric connection element in contact with the lead effectively extends the lead. A second Kelvin contact is formed of a second electric contact element and an electric connection element, the second electric contact element in contact with the electric connection element and the electric connection element in contact with the lead.
A method for providing Kelvin contacts to a lead of a small-size semiconductor device, the contacts suitable for use in testing the device with large currents at high frequencies, comprising the steps of: bringing together a first contact element and the lead until the first contact element makes contact with a first point on the lead; maintaining a predetermined spatial relationship between the first contact element and a second contact element; and bringing together an electric connection element and the lead, the electric connection element having a first end and a second end, until the first end contacts a second point on the lead and the second end contacts the second contact element.
