Abstract

An object of the invention is to provide a method and apparatus for observing inside structures and a specimen holder, wherein aging degradation of a good sample to a bad sample can be tracked in the same field of view, using the same specimen in order to determine the mechanism of failure. The present invention is a method for observing inside structures. The method comprises irradiating a specimen with a corpuscular beam generated from a corpuscular beam source, detecting transmitted particles transmitted by the specimen, applying a voltage to a portion of the specimen, and observing of a detection status of the transmitted particles in the voltage-applied portion as needed.

Claims (9)

1. A specimen holder for observing inside structures comprising:

a specimen holder main body;

a probe base disposed on said main body and provided with multiple probes;

a specimen holding base positioned to face said probe base, said specimen holding base holding a specimen; and

an interconnect connected to electrodes disposed on said probe base for applying a voltage to said electrodes,

wherein the holder has at least two probes, and changes induced in inside structures of a specimen are observed when the probes are allowed to come into contact with the specimen at different points.

2. The specimen holder for observing inside structures according to claim 1 , wherein either said probe base or specimen holding base can be moved and includes a fine adjustment mechanism for three axis directions perpendicular to one another using a piezoelectric device.

3. The specimen holder for observing inside structures according to claim 1 , said specimen holder being adapted for lateral entry into an electron microscope.

4. The specimen holder for observing inside structures according to claim 1 , wherein the contact angle between said probe and specimen is perpendicular or inclined.
