Title: Manufacture of phase-shift diffraction grating
Inventor: KIMURA TATSUYA
IPC: H01S5/00
Filed: 1989-02-21
Abstract: PURPOSE:To prevent a transition width from being produced by a method wherein, after a region used as a first diffraction grating face has been exposed to light by using interference waves, a substrate is moved, by a prescribed distance, in a direction in which interference fringes are arranged and a region used as a second diffraction grating face is exposed to light by using the interference waves. CONSTITUTION:Regions 39a, 39b used as a first diffraction grating face of a photoresist 32 are exposed to light by using interference waves 37a, 37b; after that, a substrate 31 is moved, by a prescribed distance, in a direction in which interference fringes are arranged; regions 39c, 39d used as a second diffraction grating face are exposed to light by using the interference waves 37a, 37b. Accordingly, the photoresist 32 used as a mask when a phase-shift diffraction grating 40 is formed may be either a negative resist or a positive resist. Thereby, when an etching operation is executed by intermingling the negative resist with the positive resist, a transition width by which the diffraction grating is not formed cannot be produced.

Title: Charged particle source
Inventor: SAKUMICHI KUNIYUKI
IPC: H01J37/073
Filed: 1987-02-27
Abstract: PURPOSE:To make a pulse focusing beam of a C Hz band to be produced without expanding an energy width by generating a standing wave with a mechanical vibration wave sent to a liquid material covering a needle-state electrode, periodically changing a shape of a charged particle radiant point, and periodically changing on electric field strength of the radiant point. CONSTITUTION:A liquid material 2 adhered to the surface of a needle-state electrode 1 is made to a conical shape by a static electricity strength by an electric field produced by the electrode 1, an auxiliary electrode 5, and drawer type electrode 6 in which a suitable electric potential is impressed respectively. When an oscillator 8 is driven in the condition, a mechanical vibration wave is produced in the material 2, and standing waves 3 and 4 are generated. In this case, a wave length and shape of the standing wave change by a driving frequency and a surface tension or density of the material 2. This causes a radius of curvature of the tip to be periodically changed also an electric field strength to be periodically changed, and the use of a ultrasonic oscillator as an oscillator for giving a mechanical vibration enables a pulse from several K Hz to several G Hz to be produced.
