Abstract:
1. A process condition monitoring device comprising: a substrate having a first perimeter, the substrate comprising sensors to measure the processing conditions of the substrate at different areas of the substrate; an electronics module having a second perimeter that encloses the same or less area than the first perimeter, the module comprising: signal acquisition circuitry coupled to an output of the sensors; data transmission circuitry coupled to the signal acquisition circuitry; a power source; and leads connecting the substrate to the electronics module for transmitting signals between the substrate and the electronics module, the leads providing a flexible connection that allows relative movement between the substrate and the electronics module, wherein the leads are sufficiently flexible to allow relative movement of the electronics module and/or substrate between at least a first position and a second position, wherein in the first position the electronics module is above or below the substrate, and in the second position the electronics module and the substrate are displaced from each other such that the first and the second perimeters do not intersect; and a remote data processing system, and wherein the data transmission circuitry comprises a wireless transceiver to transmit the processing conditions to the remote system.
