Abstract:
A ceramic cantilever paddle for use in semiconductor wafer processing which comprises a carrier zone extending from a handle via a carrier transition zone wherein the handle comprises two sections comprising:a) a large diameter section having a proximal end and a distal end, the distal end of the large diameter section extending to the carrier transition zone; and b) a small diameter section having a proximal end and a distal end, the distal end of the small diameter section extending to the proximal end of the large diameter section via a handle transition zone; â€ƒthe handle having an effective length â€œAâ€  commencing from the proximal end of the small diameter section and extending to the carrier transition zone, and wherein: i) the handle transition zone begins at the proximal end of the small diameter section along the effective length â€œAâ€  of the handle no further distally than the midpoint of the effective length â€œAâ€ ; ii) the height of the large diameter section of the handle is no greater than twice the height of the small diameter section of the handle; and iii) the length of the handle transition zone is no more than half of the effective length â€œAâ€ .
