MEDUSA (Materials and Electronic Devices Universal System Analyzer) is
a computer controlled automated workstation capable of conducting eight different
experiments, under different independent parameters, and plotting twenty-eight
different graphs representing basic semiconductor diode and transport characteristics.
This thesis discusses the methodology of computer automation, and the development
of the MEDUSA experimental test station.
MEDUSA is divided into four different sections: a controlling batch file, a
parameter selection routine (PARAMETER), an experimental running routine
(RUNIT), and a data manipulation/plotting routine (GRAPHICS). MEDUSA
conducts these eight experiments (capacitance and conductance versus time, voltage,
current versus voltage, van der Pauw, and four-point resistivity) over a temperature
range of 10-600K, with minimal operator interaction.
The graphics routines, using elemental semiconductor equations, process the
data, and plots high quality graphs suitable for publication. Device and material
results are shown to substantiate the validity of this automated system.
