Methods for obtaining and analyzing digital interferometric data for computer testing and developing semiconductor and anisotropic devices and materials
An interferometric holographic instrument enables the generation of digital data for testing and enabling 2-dimensional and 3-dimensional analysis of “live” and real-time semiconductor or anisotropic devices and materials. The digitally recorded interferometric data can be displayed, stored or connected to a live data stream for transmission to digital processing devices. A digital electric processor or analyzer connected to the recording device, or live data stream, enables the interferometric data to be utilized to test, develop, and shape semiconductor and anisotropic microelectronic processing, wireless and microwave devices.
1. A method of obtaining digital data for determining, shaping or testing a semiconductor or anisotropic device or materials under test comprising:
(a) providing a beam of light from a light source having a first wavelength;
(b) in a first beam instance imposing said beam of light on a test device over a spatial region within said test device substantially greater than said first wavelength, wherein said test device has a first state of refractive indexes;
(c) in a second beam instance imposing said beam of light on said test device over said spatial region within said test device, wherein said test device has a second state of refractive indexes;
(d) obtaining, displaying, transmitting, processing, or storing first electric digital data resulting from the interference of said first beam instance within said device under test representative of voltages within said region and obtaining second electric digital data resulting from the interference of said second beam instance within said device under test representative of the voltages within said region, and comparing by electric digital data processing said first and second electric digital data to determine operating characteristics within said device under test;
(e) displaying, transmitting, processing, or storing at least one of said operating characteristics; and
(f) wherein said first state of refractive indexes is at a first voltage potential or electromagnetic field state, and wherein said second state of refractive indexes is at a second voltage potential or electromagnetic field state different from said first voltage potential or electromagnetic field state.
