Title: Scanning electron microscope measuring microscale and method of fabricating same
Inventor: DEEBITSUDO BURITSUGUSU BARAADO
IPC: G01B11/02
Filed: 1977-10-24
Abstract: A microscopic length scale typically about 50  mu m long and graduated in several intervals ranging from 1  mu m to 20  mu m. The scale is useful in calibrating the magnification of scanning electron microscopes (SEMs) and other electron imaging instruments. The scale comprises alternating layers of two metals deposited on a substrate. The two metals have substantially different electron emission coefficients to provide contrasting emission signals when scanned by an electron beam. One of the metals, preferably gold, is deposited in uniform layers about 40-80 nm thick. The other metal, preferably nickel, is deposited in several layers ranging from 1  mu m or so thick near the substrate to 20  mu m thick in the outermost layer. The resultant multilayer composite is cut into one or more samples and each sample is mounted on edge. The exposed edge is ground and metallographically polished and a microscopic indentation is made in the substrate near the first gold layer. The indentation defines a reference region, and the distances between the first gold layer and the subsequent gold layers in the reference region are measured. The measurement is made using a similar sample which was previously calibrated with the aid of a polarizing laser interferometer.

Title: Connection of ic interconnections
Inventor: ITO FUMIKAZU
IPC: H01L21/28
Filed: 1987-05-27
Abstract: PURPOSE:To enable an IC to be debugged or corrected, by determining an end point of cutting of an notch in an upper interconnection layer, based on change in potential caused at a part contacted with the upper interconnection layer by the cutting so that an insulating film is provided with a fine hole. CONSTITUTION:A connecting hole 6 is deepended until an upper interconnection layer 2 is exposed. Formation of a notched groove 8 is proceeded. During the formation thereof, the connecting hole 6 previously formed is scanned with an ion beam at predetermined intervals so that secondary particles are detected by a secondary particle detector 9. A part of the interconnection layer 2 surrounded by the notch groove 8 is electrically isolated by the notch groove 8 and the part is charged up by the application of the ion beam to the hole 6. An amount of generated secondary electrons is thereby increased and the brightness of an image as observed by a secondary electron detector is also increased. The end point of the formation of the notch groove in the interconnection 2 is determined based on these phenomenon. The hole 6 is further deepened until it reaches a lower interconnection layer 4. Thus, an insulating film 3 can be provided with a fine hole and the IC is enabled to be debugged or corrected.

Filed: 1980-09-16
Abstract: PURPOSE:To preferably seal by welding a seam welded sealed semiconductor device formed by seam welding a metal cap on a laminated ceramic package and to airtightly hold the device by forming the profile of the metal cap analogous in shape  but smaller in size than the profile of the welding ring. CONSTITUTION:After a welding ring 5 and an external lead 4 are soldered to a laminated ceramic 2, a semiconductor element is associated with a laminate ceramic package formed by plating nickel as primary layer and gold 8 on a mount 7, a bonding part 6, a welding ring 5 and an external lead 4. Then, the throttled part of a metallic cap 3' is engaged with the bore of the ring 5 to perform a seam welding. Since the profile of the welding ring is formed smaller than that of the metallic cap at this time, a gold-nickel alloy is obtained by seam weld sealing, with the result that airtightness is retained, and improper leakage can be remarkably reduced.

Title: High frequency power supply
Inventor: NAGAI KOICHI
IPC: G01R31/25
Filed: 1998-04-21
Abstract: PROBLEM TO BE SOLVED: To prevent system down by deterioration of vacuum tubes to assure element analysis of a sample in an induction heating furnace, by outputting an operation life end warning signal through judgment of operation life from the deterioration characteristic of vacuum tube indicated by a DC current. SOLUTION: Since deterioration characteristic of a vacuum tube is almost linear, deterioration can surely be assumed accurately from the maximum current. When a setting value of an ordinary plate current setting signal Ipset1 is 350 mA, a setting value of the setting signal Ipset1' is set to 500 mA under the condition of setting the life time of a vacuum tube Ov, and it is inputted for about three second. When the plate current Ips1 becomes lower than the plate current setting signal Ipset1', a warning signal is outputted the warning signal output circuit 13. As a result, since the operation life of the vacuum tube can be forecasted, system-down by deterioration of vacuum tube can be prevented to surely conduct element analysis of sample in the induction heating furnace.
