A contactor for semiconductor devices includes a base unit for holding a semiconductor device provided with a plurality of terminals and a wiring substrate provided with contact electrodes at positions corresponding to at least some of the terminals. The contact electrodes and the terminals are electrically connected when the wiring substrate is held on the base unit. The contactor further includes a position maintaining force applying mechanism for applying a position maintaining force between the base unit and the wiring substrate and a contact pressure applying mechanism for applying a contact pressure between the semiconductor device and the wiring substrate. The position maintaining force applying mechanism and the contact pressure applying mechanism are operable in an independent manner.

摘要:
An IC bare chip carrier installs an IC bare chip for performing a burn-in test and a functional examination of the bare chip. The carrier consists of an installing unit for installing the bare chip and an interconnecting unit for electrically interconnecting chip electrodes of the bare chip with output electrodes of the interconnecting unit, to be connected to apparatus for the burn-in test and the functional examination. The installing unit is made of aluminium nitride having an expansion rate near of material, ceramic, of the IC bare chip, for making fabrication of installing surface of the IC bare chip easy. The interconnecting unit has an air exchange mechanism by which the IC bare chip can be laid in a space, made by combining the installing unit and the interconnecting unit, constantly filled with inert gas such as nitrogen. The IC bare chip is transported anytime and anywhere as installed in the carrier without being contaminated.
