| Description |
NIST made the first programmable 1-volt standard, which had 32,768 junctions on a 1-centimeter square chip. This was the first demonstration of the new normal-metal junction barrier technology that produced large numbers of junctions with uniform electrical characteristics, even though each junction is only 2 micrometers by 2 micrometers in size. Programmable arrays are ideal for automated measurement systems. The stability of the programmable steps enabled the first detailed characterization of voltmeters.
