Wafer grounding and biasing method, apparatus, and application

A wafer grounding apparatus and method adaptable to a charged particle beam apparatus is disclosed. A wafer substrate is supported by a wafer mount. A pulse current pin is arranged to be in contact with a backside film formed on a backside of the wafer substrate. A grounding pulse generator provides at least one pulse to drive the pulse current pin such that dielectric breakdown occurring at the backside film leads to establishment of a current path through the backside films. Accordingly, a current flows in the wafer substrate through this current path and then flows out of the wafer substrate via at least one current return path formed from capacitive coupling between the wafer substrate and the wafer mount.

The temperature of the support structure may be controlled and/or gases or liquids may be confined in the observation region for reactions and/or imaging.

Sample holder

A sample holder includes an adapter attached to an adapter attaching part. An analysis target, e.g., analytical cell, has first electrical connection members. The adapter has second electrical connection members. The number of the first electrical connection members and the number of the second electrical connection members are the same. Further, the adapter has third electrical connection members, and the adapter attaching part has fourth electrical connection members. The number of the third electrical connection members and the number of the fourth electrical connection members are the same. For example, the third electrical connection members are six electrically conductive membranes, i.e., a first electrically conductive membrane to a sixth electrically conductive membrane. Among the six electrically conductive membranes, only the third electrically conductive membrane is not electrically connected to any of the second electrical connection members and the first electrical connection members.

Fixture for in situ electromigration testing during X-ray microtomography

Systems and fixtures for mounting, under mechanical constraint, wire-like or fiber-like samples of a high aspect ratio and down to 100 micrometers in diameter are disclosed. A region of interest along the length of the sample resides between and beyond a mechanical constraint on either side, allowing access to the region of interest for a wide number of characterization probes. The fixture may provide electrical isolation between two retaining blocks by means of a dielectric support member. The design may achieve minimal thermal expansion along the length of the sample by the material selection for the dielectric support member. Electrical contact may be introduced to the sample through conductive constraints in the retaining blocks. The fixture may have a minimal size perpendicular to the length axis of the sample to facilitate high probe fluxes when a diverging probe is used. The fixture may provide high x-ray transparency between the retaining blocks. The systems and fixtures as described therefore may provide a means for performing electrical and thermal testing on samples, including but not limited to solder butt-joints, across multimodal in situ characterization and imaging techniques to analyze dynamic electromigration.
