Abstract:
An apparatus for sensing temperature on a substrate in an integrated circuit fabrication tool, comprising:a substrate having a surface containing a plurality of small cavities thereon;a plurality of sensors each bonded within a corresponding cavity of said substrate with an adhesive and potted with a potting compound, each of said sensors having sensor leads protruding through a potting layer formed by said potting compound;an interconnect system joining at least one filament to each of said sensor leads, each of said filaments coated with a wall of insulating material for mechanical protection;a strain relief structure coupled to a base of said substrate, said filaments converging at said strain relief structure;a cable assembly having a flat cable portion, including:(a) an array of flat signal transmitting cables arranged side by side, each of said signal transmitting cables formed by bonding a plurality of said filaments side by side with an adhesive;(b) a pair of ribbons extending along the length of said array of signal transmitting cables, each on an opposed side thereof and held together with one or more sheets of film to form said flat cable portion having a first end and an opposed second end, said ribbons welded to a first side of said strain relief at said first end of the flat cable portion; and(c) a protective boot disposed around said second end of the flat cable portion, said signal transmitting cables extending therethrough; anda connector coupled to an end of the cable assembly and said filaments contained within the cable assembly terminated to said connector.
