In one embodiment, a connector is made using a mixture of insulating silicone powder and conductive powder. The connector comprises a connector body formed from the insulating silicone powder and on or more preferably regularly arrayed conductive silicone members that are formed by migrating the conductive powder to a site of the connector corresponding to a solder ball of the semiconductor package. The conductive silicone member comprises a high-density conductive silicone part formed to be proximate an upper surface of the connector body and to protrude therefrom and a low-density conductive silicone part formed in substantial vertical alignment beneath the high-density conductive silicone part, the low-density conductive silicone part having a lower surface exposed from a lower surface of the connector body.

摘要:
There are provided a probe card for test of semiconductor chips and a method for testing semiconductor chips using the probe card. In implementing the probe card for electrically testing semiconductor chips, the probe blocks corresponding to multiple selected ones of the semiconductor chips on the wafer can be selected so that the selected semiconductor chips are EDS tested in a one-step process. As the selected semiconductor chips are EDS tested in a one-step process, equipment efficiency is improved, and statistical objectivity of data indicating characteristics of the wafer can be achieved.
