The present invention is directed to a method of forming a clamping plate for
a multi-polar electrostatic chuck. The method comprises forming a first electrically
conductive layer over a semiconductor platform and defining a plurality of portions
of the first electrically conductive layer which are electrically isolated from
one another. A first electrically insulative layer is formed over the first electrically
conductive layer, the first electrically insulative layer comprising a top surface
having a plurality of MEMS protrusions extending a first distance therefrom. A
plurality of poles are furthermore electrically connected to the respective plurality
of portions of the first electrically conductive layer, wherein a voltage applied
between the plurality of poles is operable to induce an electrostatic force in
the clamping plate.
