Patent ID: 7243410

Claim:
A method for manufacturing a probe card, which comprises a contact provided on a base substrate and electrically coupled to a terminal of an electronic device, for receiving and/or sending a signal from and/or to said electronic device, comprising: a first contact formation step of forming a first contact on a first surface of a first sacrificial substrate; a second contact formation step of forming a second contact on a first surface of a second sacrificial substrate; a signal transmission line formation step of forming a signal transmission line in said base substrate; a first contact joining step of attaching said first surface of said first sacrificial substrate to said base substrate and joining said first contact to said signal transmission line; a second contact joining step of attaching said first surface of said second sacrificial substrate to said base substrate and joining said second contact to said signal transmission line; and a first sacrificial substrate elimination step of eliminating said first sacrificial substrate after said first contact is coupled to said signal transmission line in said first contact joining step.
