Abstract:
An apparatus for transmitting signals from a planarizing device, the planarizing device having a support structure, a platen assembly connected to the support structure, and a carrier supported over the platen assembly and coupled to the support structure, the carrier being movable relative to the platen assembly and the support structure to remove material from a semiconductor substrate positioned between the carrier and the platen assembly, the apparatus comprising:a force sensor connected to the carrier, the carrier being further comprised of a mounting member removably coupled to the support structure, and an engaging member to engage the semiconductor substrate, the force sensor being connected between the mounting member and the engaging member to generate a signal corresponding to a force transmitted therebetween; an electronic device spaced apart from the sensor; and a wireless communication link coupled between the sensor and the electronic device to transmit the signal from the sensor to the electronic device.
