Title: Evaluation method for semiconductor substrate surface
Inventor: TERAJIMA KOICHI
IPC: H01L21/66
Filed: 2000-02-23
Abstract: PROBLEM TO BE SOLVED: To be able to easily measure interface level densities of an insulating film/a semiconductor substrate for a monitoring check at a manufacturing step for a semiconductor device. SOLUTION: Interface level densities of an insulating film and a semiconductor substrate are calculated by radiating laser 2 on the surface only of the semiconductor substrate of a material 1 having an insulating film, a semiconductor substrate construction by transmitting through the insulating film and by measuring PL light 3 via a spectrometer 5, a detector 6, a lock-in amplifier 7 and so on. Here the interface level density of the unknown material is calculated by relatively comparing the strength of the PL light from the material having a known interface level density to the strength of the PL light from the material having an unknown interface level density. Alternatively, a calibration curve which indicates a relation of the PL light strength and the interface level density is previously calculated.  After that, a interface level density of the material is calculated by measuring whole strength of the PL light of the material having an unknown interface level density and by comparing to the calibration curve.

Title: Equipment for measuring feeble magnetic field, method for extracting required component and equipment for measuring the component
Inventor: ADACHI YOSHIAKI
IPC: G01R33/02
Filed: 2000-03-10
Abstract: PROBLEM TO BE SOLVED: To suitably obtain a feeble magnetic field at all times even if there are variations in an external magnetic field.
