Application No. 08/995,706
transfer machine includes a base plate having a first portion
upon which a send cassette is supported and a second portion
upon which a receive cassette is supported; a first axial
slot/positioner disposed on the first portion of the base; and
a second axial slot/positioner disposed on the second portion
of the base and a transfer arm operatively coupled to the base
and moveable along a longitudinal axis at least over the first
portion of the base. In addition, Figures 1-4 of Model WT-6HL
shows the base plate having positioning dots and four axial
slot/positioners to permit the horizontal wafer transfer
machine to be used with various combinations of high profile
cassettes and low profile cassettes. Figures 1-4 of Model WT-
3456 shows the base plate having adjustable positioning dots
and eight axial slot/positioners to permit the horizontal
wafer transfer machine to quickly convert for use with most H-
bar 3, 4, 5 and 6 inch high profile cassettes.
Yap's invention relates to an apparatus for securing an
automatically loaded wafer cassette on a wafer processing
equipment, wherein the apparatus allows maximized positional
displacement of the wafer cassette being loaded on the
