Disclosed herein is an equipment for sticking a vinyl tape on the backside surface of a wafer prior to the dicing of the wafer. Suction ports for sucking and supporting the peripheral part of the wafer surface is provided in the outer block of a stage for supporting the wafer, a recessed part is formed at the central part of the support stage so as to avoid the contact of the central part of the wafer to the support stage, and concentric ring-shaped projection parts are formed on the bottom surface of the recessed part. The height of the top face of the ring-shaped projection parts is set to be slightly lower than the outer block of the support stage which is the wafer contact part, with minute gaps being kept from the fixed wafer. It is possible to prevent the generation of flexure due to a turning roller at the time of sticking of the tape by introducing high pressure air to the recessed part of the wafer support part and the minute gaps.

In a laser processing machine 100 including a plurality of element units containing at least a laser blower unit 3, an optical-path purge unit 24, and a temperature controlling unit 8, a measurement unit and a control unit 10 are provided. The measurement unit measures an elapsed time from a final trigger at which a laser processing operation of the laser processing machine has stopped and no user operation is applied with respect to the laser processing machine. The control unit 10 stops the element units based on the elapsed time after the final trigger, when a condition specified for each of the element units is satisfied.

The sealed gas laser oscillator that includes the airtight vessel, the laser gas supply source that supplies a laser gas to the airtight vessel, and the vacuum pump that performs evacuation until a pressure of an inside of the airtight vessel reaches a target reached pressure every predetermined interval between laser gas exchanges and is connected to the airtight vessel, and that performs laser oscillation in a state where the airtight vessel is filled with the laser gas. The gas laser oscillator includes a unit that determines the target reached pressure on the basis of the interval between laser gas exchanges, a leakage rate of an impurity gas from the outside to the airtight vessel after evacuation, and an allowable impurity gas pressure at which the gas laser oscillator is capable of being operated.

There is to be provided a liquid crystal drive controller with a built-in power supply circuit wherein latch-up is made difficult to arise even if one amplitude level of the segment line drive voltage is set to the ground potential and the levels of other liquid crystal drive voltages are determined accordingly. A semiconductor integrated circuit with a built-in power supply circuit, wherein a negative voltage generated in a power supply circuit is applied to a substrate or a well region as a bias voltage, is provided with a switch for temporarily applying the ground potential to the substrate or well region to be biased with the negative voltage at the time of starting up the power supply circuit.
