Title: Manufacture of fluorescent panel for electronic micro scope
Inventor: MIZUNO HIROYUKI
IPC: H01J37/22
Filed: 1977-11-25
Abstract: PURPOSE: To ensure the production of the exactly same fluorescent panel with a uniform line at all times by fixing the mark projection material at the position of the mark provided on the substrate surface and then coating the fluorescent paint on the substrate surface excluding the mark projection through the sedimentation method or the like.  
     CONSTITUTION: First, mark projection material 11 featuring the same shape and size as the mark is welded at the fixed mark attaching position on substrate 10 made of metal and other materials. Then fluorescent paint 12 is coated on substrate 10 through the sedimentation method, etc. In this case, material 11 is above the surface of substrate 10, and thus no paint 12 sticks to 11. As a result, the area of projection 11 has no light emission even with irradiation of the electron beam, thus functioning as the mark. In such method, the uniform line lead-out is always possible for the concentric circles or frames with no defective product virtually produced.

Title: Semiconductor device
Inventor: HINODE KENJI
IPC: H01L21/28
Filed: 1988-06-10
Abstract: PURPOSE:To obtain a titanium nitride film which is superior in treatment by causing a part of the titanium nitride film to have an oxygen concentration in its film which is one atomic percentage or less. CONSTITUTION:At least a part of a titanium nitride film has an oxygen concentration in its film which is one atomic percentage or less. When the oxygen concentration in the titanium nitride(TiN) is high, the speed of etching becomes slower. Although its dependence on the oxygen concentration is low, the rate of etching increases gradually with the decrease of the concentration and then, in case where one atomic percentage becomes less than 1, the rate of etching increases rapidly. As a result, a state of TiN where its oxygen concentration is less than one atomic percentage makes etching gain in speed and the selective ratio of etching speed to the amount of substrate-SiO2 increases. Such a large selective ratio makes it possible to perform treatment accurately and the lower the oxygen concentration, the greater is its effect.
