  We present imaging observations of the evolved star IRC+10216 in the CS
J=14--13 line at 685.4 GHz and associated submillimeter continuum at about 2''
resolution made with the partially constructed Submillimeter Array. The CS
J=14--13 line emission from the stellar envelope is well resolved both
spatially and spectrally. The strong central concentration of the line emission
provides direct evidence that CS is a parent molecule that forms close to the
stellar photosphere, in accord with previous images of the lower excitation CS
J=2--1 line and inferences from unresolved observations of vibrationally
excited transitions. The continuum emission is dominated by a compact,
unresolved component, consistent with the photospheric emission, that accounts
for about 20% of the broadband 450 micron flux. These are the first
interferometer imaging observations made in the semi-transparent 450 micron
atmospheric window.
