Abstract:
1. An optical probe system for probing an electronic device, comprising: a sample plate configured to hold a target device comprising an integrated circuit; a temperature control chamber configured to hold a fluid to control the temperature of the target device; a rotational stage comprising a plurality of ports each configured to receive and hold one of a plurality of optical objective systems that include a first optical objective system, wherein the first optical objective system is mounted to one of the plurality of ports that defines a staging position, wherein the first optical objective system is configured to collect reflected or emitted light from the integrated circuit in the target device; a shaft around which the rotational stage is rotated; a fixed frame that is configured to remain stationary when the rotational stage is rotated; a flexible circuit having one end attached to the shaft and another end connected to the fixed frame, wherein the flexible circuit is wound around the shaft with sufficient slack to allow free rotational movement of the rotation stage; a vertical translation stage configured to move the first optical objective system in a vertical direction substantially perpendicular to the sample plate, wherein a portion of the first optical objective system is moved through the temperature control chamber to allow the first optical objective system to focus at the integrated circuit in the target device; and an x-y translation stage configured to move the first optical objective system in horizontal directions substantially parallel to the sample plate.
