Title: Optical beam scanner and its manufacture
Inventor: HASEGAWA SHINYA
IPC: G02B27/00
Filed: 1985-07-31
Abstract: PURPOSE:To lower the astigmatism and coma of scanning light and to reduce the jitter of the scanning light caused by mode hopping, by constituting an optical beam scanner in such a simple constitution that is composed of a semiconductor laser, hologram lens for aberration correction and hologram scanner. CONSTITUTION:Divergent spherical waves 4 coming out from a semiconductor laser 2 are made incident on a hologram lens 1 for aberration correction and diffracted waves 5 from the lens 1 are made incident on a discoidal hologram scanner 3 which rotates with a beam diameter DH. Diffracted waves 6 of convergent spherical waves from the scanner 3 form their image at an image forming point 7 on a photoconductive drum and perform scanning. In this constitution, the angle of diffraction of the hologram lens 1 is set in such a way that slippage of the image forming point caused by the hopping of the longitudinal-mode wavelength of the semiconductor laser 2 can be prevented. At the same time, the hologram lens 1 for aberration correction is prepared by using the laser light having a shorter wavelength than the semiconductor laser light has, so that the lens 1 can produce a wave surface having aberration which can offset astigmatism and coma produced by the hologram scanner 3 after receiving the divergent light coming out from the laser 2.

Title: Device and method of evaluating semiconductor
Inventor: ITO YOSHIHIKO
IPC: H01L21/66
Filed: 1998-06-17
Abstract: PROBLEM TO BE SOLVED: To permit nondestructive measurements of carrier densities and dopant distributions at a space resolution in the order of nanometers by measuring emitted light induced by a tunnel current flowing across a probe and a specimen, thereby directly obtaining information proportional to the density of carriers in a semiconductor. SOLUTION: A drive power source 3 applies a voltage between a specimen 4 and a probe 1, and a piezoelectric element 11 controls the position of the probe 1. A tunnel current 2 flows through the specimen 4 from the probe 1, thereby inducing a localized plasmon mode with main carriers within the specimen 4 and hence emitting light 5 having an energy determined by the carrier density. The emitted light is thereafter divided by a spectrometer 7, detected by a light detector 8, then converted into electrical signals by an electrical circuit 9 to thereby measure their intensities. Through the scanning of the probe 1, the intensity of the tunnel current measured by an ammeter 12 and, at the same time, the in-plane distribution of the light 5 are displayed on a CRT 10.  Further, the in-plane distribution of carriers is determined based on the in-plane distribution of peak energies of emission spectrum.
