Title: Detecting method for defect of insulating film buried in semiconductor board
Inventor: HAMAGUCHI ISAO
IPC: H01L21/66
Filed: 1993-05-31
Abstract: PURPOSE:To accurately locate defects in a short time by a method wherein a semiconductor board is irradiated with an electron beam to generate carriers, and carriers are led out and checked in quantity change. CONSTITUTION:If no pipe defect 4 is present in a buried oxide film 2 irradiated with an electron beam 7, only carriers 8 generated inside a surface silicon layer 1 are able to reach a space-charge layer 6 by scattering. On the other hard, if a pipe defect 4 is located in a buried oxide film 2 irradiated with an electron beam 7, not only carriers 8 generated in the surface silicon layer 1 but also carriers generated even in a board 3 region are able to reach the space-charge layer 6 and led out as external signals. Therefore, a part of the oxide film 2 where carriers are relatively high in yield is detected as a spot, where a pipe defect 4 is located. The contrast signal of a scanning electron microscope is modulated with this carrier yield, whereby a pipe defect 4 can be easily defined as a microscopic image.

Filed: 1984-06-23
Abstract: PURPOSE:To obtain an reactive ion beam etching device of good etching characteristics and a long life utilizing a plasma distribution of good uniformity by providing a filament vortically in an inert gas with separating it from a reactive gas. CONSTITUTION:Thermoions generated by heating a vortical tungsten filament 14 activate an inert gas 12 of Ar, Xe and etc. As the filament 14 is shaped flatly and vortically and is arranged symmetrically for a flow of the inert gas 12, the thermoions are generated uniformly. Accordingly, an inert gas plasma is made relatively uniform and it is drawn out by a high voltage for an electrode 16. This inert gas plasma activates a reactive gas 3 of CCl4, CF4 and etc. At this time, distribution of active and reactive gas ions 5 becomes relatively uniform. Consequently, the distribution of reactive ion beams 8 which are obtained by accelerating said gas ions 5 by a negative high voltage applied to an acceleration electrode 7 also becomes uniform and etching of an insulating film and a metallic film on a wafer to be processed 10 can be done uniformly.

Abstract: PURPOSE:To obtain easily a surface combustion burner according to the shape of a combustion chamber and the capacity of a boiler by disposing straightening fins for straightening a flow of a fuel gas toward a burner element, in a multiplicity of layers in a burner duct. CONSTITUTION:A fuel-air premix introduced through a connecting port 22 is guided by straightening fins 30a-30d, and is distributingly supplied to small element 10' at uniform pressures. Thus, the premix is supplied uniformly over the entire body of a burner element 10. Since the flow direction of the premix is changed without such a pressure loss as in the case of a punched metal, the pressure at the time of supplying the premix can be reduced, and it is unnecessary to enhance the capability of a premix-supplying means, so that a small, lightweight and inexpensive premix-supplying means can be used. A surface combustion can be applied satisfactorily to a boiler in which the spacing between water tubes is small and the height of a furnace is large, and a variety of surface combustion burners can be easily produced according to the shape of a combustion chamber for the boiler and the quantity of heat required.
