Title: Discharge display element
Inventor: TSUCHIYA MASASHI
IPC: H01J61/92
Filed: 1996-02-06
Abstract: PROBLEM TO BE SOLVED: To apply a phosphor highly effectively and simply, at a low discharge starting voltage, by making the cross section form in the vertical direction to the face plate of the discharge hole of a discharge display element, in a taper form expanding to a common cathode. SOLUTION: The inside of the discharge tube body 5 of a discharge display element 1 is partitioned into luminous small chambers 6a to 6d. At the bottom part of the luminous small chambers 6a to 6d, taper form of discharge holes 8a to 8d which are made as the discharge routes to a common cathode 2, and have a cross section form of inclination expanding to the common cathode 2, are provided. A phosphor 9 is applied to the inner wall surfaces of the luminous small chambers 6a to 6d. At the face plate side of the luminous small chambers 6a to 6d, anodes 7a to 7d which carry out the discharge selectively with the common cathode 2 respectively are provided. Consequently, the thickness of the minimum section area parts of the discharge holes 8a to 8d is made thinner, and the discharge is started easily.  In this case, by providing a step at the common cathode 2 side of each discharge hole 8 so as to reduce the thickness of the discharge hole, the same effect can be obtained. The discharge display elements are aligned so as to form an image display device.

Title: Manufacture of semiconductor device
Inventor: HARADA YOSHIKAZU
IPC: G03F7/20
Filed: 1983-02-09
Abstract: PURPOSE:To improve the accuracy of the positioning during the manufacturing process by a method wherein a positioning mark is scanned by an electron beam and a produced characteristic X-ray is detected and the positioning is performed according to this detected signal. CONSTITUTION:An L-shape positioning mark 5, made of platinum-silicon alloy, is formed on the surface of a semiconductor substrate 1 and a resist film 4 is formed so as to cover the surface and the mark 5. When the positioning mark 5 is scanned by an electron beam 3, a characteristic X-ray of Pt is produced from the positioning mark 5 and the X-ray signal can be detected. The characteristic X-ray signal of Pt can be securely detected if the thickness of the resist film 4, formed over the positioning mark 5, is not more than about 2mum. In other words, the characteristic X-ray is securely produced from the positioning mark 5 made of Pt-Si if the electron beam can penetrate. Therefore, even if the positioning mark 5 is covered by the resist film 4, the electron beam, which is strong enough to expose the resist film 4, can produce the positioning signal sufficiently.
