Abstract: Methods, systems, and apparatus for measuring a gap between a support surface for a substrate and an opposing upper surface of a processing chamber. The methods comprise: disposing a sensor substrate at a location spaced between the support surface and the upper surface, the sensor substrate comprising a body having a first side and a second side opposite the first side, the first side facing the support surface and the second side facing the upper surface, the first side having a first sensor and the second side having a second sensor; measuring, using the first sensor, a first distance between the first side and the support surface; measuring, using the second sensor, a second distance between the second side and the upper surface; and determining a gap between the support surface and the upper surface using the first distance and the second distance.

Abstract: A transceiver has a transmitter portion using active comparators coupled to single low level positive bias source to enable low powered drain transmit and receive conversion of TTL input signals to LLS (low level serial) data output signals for a coaxial data transmission cable. The transceiver also provides a constant impedance for a coaxial or triaxial transmission cable during active transmission periods, standby periods and power-off periods to provide a cost effective method to transmit and receive data.

Abstract: A transceiver has a transmitter portion using serially coupled FETs coupled o low level positive and negative bias sources to enable a low power drain conversion of TTL input signals to low level serial data output signals for a coaxial data transmission cable and vice versa The transceiver also provides a constant 50 ohm impedance for the coaxial or triaxial transmission cable during active transmission periods, stand-by periods and power-off periods to provide an inexpensive method to transmit and receive 10 Megabit coded data via a coaxial or triaxial cable.
