Abstract
Following a decade of rapidly shrinking linewidths, semiconductor microlithography stopped short of the predicted one micron level and hovered for most of the 1970's at five microns (or 0.2 mils). By 1979, various developments in equipment, materials and processing allowed the downward trend to be resumed. The gap between five microns and one micron appears to be closing rapidly, with micron and sub-micron lithography again being predicted for high volume manufacturing.
