Abstract: PURPOSE:To make it easy to keep the lapping margin of wiring, and increase reliability of the wiring, by making the diameter of a connection hole of an insulating film large in the wiring direction, and small in the crossing direction with the wiring. CONSTITUTION:On an n<+> layer 5 on a p<-> substrate which is separated in insulated regions 2 and 3, a gate oxide film 4 and an interlayer insulating film 7 are stacked, and a resist mask 8 is formed to make a connection hole 9. A new mask 10 has an rectangular aperture pattern which is long in the direction of wiring arrangement and has a width equal to the hole 9 in the perpendicular direction. By applying the mask 10, an anisotropic dry etching is performed, and the thickness of the insulating film 7 is made on half. The mask 10 is removed and an Al wiring 11 is formed. In the perpendicular direction to extension of the wiring 11, the wall surface is vertical, and defects of the buried wiring hardly generate. On the other hand, the connection hole 9 is in the form of a step in the direction of extension, so that the wiring 11 and the n<+> layer 5 or a gate electrode 6 are excellently connected.

Title: Thermal field emission electron gun
Inventor: SAKAI IWAO
IPC: H01J1/304
Filed: 1996-11-12
Abstract: PROBLEM TO BE SOLVED: To realize a thermal field emission electron gun having a long service life by preventing a mass of zirconium from slipping. SOLUTION: On the way to a tungsten chip 5, a wire 13 formed of tungsten is attached by spot welding. Moreover, slurry of zirconium hydride is applied to part of the wire 13 to form a mass 6' of zirconium by a sintering process at a heating temperature of approximately 1800 deg.K. In such constitution, at the time of working as an electron gun, a normal heating operation consumes zirconium at a temperature of approximately 1800 deg.K in the same manner as previously. However, even when a clearance is created between the mass 6' of zirconium and the tungsten chip 5, the mass 6' of zirconium is supported by the wire 13 to preclude its slippage.
