Patent ID: 7626410

Claim:
An apparatus for testing a semiconductor device that has opposing first and second sides, the semiconductor device including at least one functional unit on the first side and a plurality of terminals on the second side, the functional unit detecting non-electrical conditions incident thereon, the apparatus comprising: a mounting structure having at least one stage that is configured to allow the semiconductor device to be mounted thereon, the mounting structure having a communicating hole that penetrates the mounting structure from the stage, the communicating hole allowing the at least one functional unit to face the communicating hole while the semiconductor device is mounted on the stage, wherein non-electrical test conditions are applied to the at least one functional unit via the communicating hole; a supporter that supports the mounting structure and allows the mounting structure to move housing in a direction vertical to the surface of the stage; and a plurality of electrodes, each of which is configured to be contactable to a corresponding one of the plurality of terminals while the semiconductor device is mounted on the stage, wherein each of the plurality of electrodes is configured to approach a corresponding one of the plurality of terminals by moving the mounting structure in the vertical direction, wherein each of the plurality of electrodes further comprises: a flexible portion that is deformable, a first portion that has a power point, the first portion being connected to the flexible portion, the power point receiving mechanical force from the mounting structure, thereby deforming the flexible portion, and a second portion that has a contact portion, the second portion being connected to the flexible portion, wherein the contact portion of each of the plurality of electrodes is contactable with a corresponding one of the plurality of terminals while the flexible portion being deformed, and wherein the power point is pushed down by moving the mounting structure downwardly, so as to deform the flexible portion and rotate the first and second portions around the flexible portion, thereby causing the contact portion of each of the plurality of electrodes to become contact with a corresponding one of the plurality of terminals.
