Title: Control method for optical signal output circuit
Inventor: FUJISAWA TAKANORI
IPC: H01S5/00
Filed: 1988-04-15
Abstract: PURPOSE:To securely protect a human body from laser light even when an optical fiber is not connected and disconnected by guiding reflected light obtained from one output of an optical directional coupler from the other output point to a photoelectric converting circuit and turning off the light emission of an optical signal. CONSTITUTION:The output terminal of an optical signal output circuit 1 which uses a laser diode as a light emitting element is connected to the optical directional coupler 2 and the optical signal from the optical signal output circuit 1 is propagated from a 1st output point 3 of the optical directional coupler 2 to an optical connector 4. If the optical signal is reflected in the optical connector 4 owing to a nonconnection point or disconnection point, the reflected light is inputted from the 1st output point 3 to the optical directional coupler 2 again and inputted from a 2nd output point 7 to the photoelectric converting circuit 6 to become an electric signal. This electric signal is inputted to the control terminal 5 of the optical signal output circuit 1 to turn off the output of the optical signal output circuit 1. Thus, when the optical connector 4 is not connected or when the optical path is disconnected, the laser light turns off instantaneously to securely protect the human body.

Filed: 1999-03-31
Abstract: PROBLEM TO BE SOLVED: To expose a sample with a beam with high accuracy by the methods in which correction signals are generated by a correcting signal generation means, and the high frequency component is removed by a filtering means, then a sample is exposed to charged particle beam on the basis of the output signals. SOLUTION: A lens correcting circuit 325 calculates the correcting amount (correcting amount of rotation) of image rotation at each focus, and incorporates the calculated correcting amounts of rotation into converging data Dcd. A correcting DAC 324 converts the converging data Dcd into a correcting DAC output Sco and outputs the correcting DAC output Sco to a correcting LPF 323. The correcting LPF 323 removes high frequency components and generates a projection correcting signal Spc. An electron beam, which passes through a projection deflecting coil 25, forms an image on a wafer through a projection correcting magnetic field for exposing the wafer.
