Abstract:
Methods are described for obtaining digital data for determining, shaping or testing a semiconductor or anisotropic device or materials under test or manufacture. Optical interferometric techniques can sense a wide region, such as that passing through or reflected off a semiconductor material, which can then be analyzed. In this manner, various characteristics of the resultant transmitted or reflected probing beam, herein called the “object wave,” are recorded in the resultant interference pattern between the object wave and the reference beam. Likewise, when the semiconductor material, such as an integrated circuit, is stressed by applying a voltage therein by energizing a circuit fabricated therein, the same light will reflect or otherwise pass through the semiconductor material, while being affected by the changes imposed upon or acting within the interior structures or interior surfaces by an applied voltage or signal, or by an incident external stress, thereby resulting in a different pattern.

Claim (Index 5):
A method of obtaining digital data for determining, shaping or testing a semiconductor or anisotropic device or materials device under test comprising:\n (a) providing a coherent beam of light from a light source having a first wavelength; (b) splitting the light beam into a pair of beams comprising of a reference beam and an object beam, (c) imposing the object beam on the exterior surface of the semiconductor material to generate a reflected object beam reflected from the interior structures of the semiconductor material, or (k) imposing said object beam on the exterior surface of the semiconductor material to generate a transmitted object beam transmitted through the interior structures or interior surfaces of the semiconductor or anisotropic material, (d) imposing said object beam of light on a test device over a spatial region within said test device greater than said first wavelength, wherein said test device has a first state; (e) imposing said coherent beam of light on said test device over said spatial region within said test device, wherein said test device has a second state; (f) imposing the reflected object beam and the reference beam onto a detection device to create a plurality of interference patterns of the reflected or transmitted object beam with the reference beam, (g) obtaining, displaying, transmitting, processing, or storing electric digital data resulting from the interference of said object coherent beam of light within said device under test representative of the voltages or electromagnetic field states or electromagnetic signals within said region; (h) wherein said first state is at a first voltage potential or electromagnetic field state, and wherein said second state is at a second voltage potential or electromagnetic field different from said first voltage potential or electromagnetic field state or electromagnetic signal.
