According to one embodiment, a stage apparatus includes a height control unit includes height control elements each which is drove in an upward/downward direction independently, a measuring unit which divides an upper surface of the substrate into areas, and measures a height of each of the areas. The control unit is configured to set the height of each of the areas independently by controlling a height of each of the height control elements based on a data value, determine using the measuring unit whether the height of each of the areas in the upper surface of the substrate is in a allowable range, and set the height of the area out of the allowable range again by the height control elements.

An optical signal detection circuit (10) includes an amplification circuit (11) that differentially amplifies an electrical signal (Tout) corresponding to the pulse train of an optical signal (Pin) and outputs a differential output signal (Aout), and a comparator (12) that compares the voltage value of the positive-phase signal of the differential output signal (Aout) with the voltage value of the negative-phase signal and outputs a pulsed comparison output signal (Cout) corresponding to the comparison result. The amplification circuit (11) includes a current addition circuit (11E) that adjusts a DC load current to generate a positive-phase signal (Aout+) and a negative-phase signal (Aout−) of the differential output signal (Aout) in accordance with an adjusted voltage value from an external adjusted voltage source (Vadj) and adjusts the DC bias of the positive-phase signal (Aout+) and the DC bias of the negative-phase signal (Aout−).

A partial pressure control system 45 includes two valves 2 which are branched from an operation gas supply pipe 44 and which variably control operation gas, pressure sensors 3 which are respectively connected to the each valves 2 in series and which detect pressure of the operation gas, and a controller 25 which proportionally controls the operation of the valves 2 based on detection result of the pressure sensors 3, thereby relatively controlling pressures P1 and P2 of the two valves. With this configuration, it is possible to reduce wastefull consumption of the operation gas, and to enhance the responsivity with respect to change of setting and the like.
