    摘要: When performing an inspection using a charge control function in a SEM wafer inspection apparatus, acceleration voltage, control voltage and deceleration voltage are changed in conjunction so that incident energy determined by “acceleration voltage−deceleration voltage” and bias voltage determined by “deceleration voltage−control voltage” do not change. By this means, charge of a wafer can be controlled, while restraining electrostatic lens effect generated near a control electrode. As a result, an inspection using a charge control function at low incident energy and in a wide viewing field can be performed, and a highly sensitive inspection of semiconductor patterns subject to damages due to electron beam irradiation can be realized. Acceleration voltage, control voltage and deceleration voltage are changed in conjunction so that incident energy determined by “acceleration voltage−deceleration voltage” and bias voltage determined by “deceleration voltage−control voltage” do not change.

    摘要: In a refrigerating apparatus in which a plurality of application-side heat exchangers (41, 45, 51) are connected to a heat-source side heat exchanger (4), liquid lines for a plurality of channels in a refrigerant circuit (1E) share a liquid side communication pipe (11) in order to reduce the number of pipes. Further, the liquid side communication pipe (11) is provided adjacent to a low-pressure gas side communication pipe (15) for at least one channel so as to contact it in order to supercool a liquid refrigerant by a low-pressure gas refrigerant. Thus, workability for connecting the pipes is improved and a refrigerating ability may not be decreased even if communication pipes (11, 15, 17) become long.
