IPC: H01L21/027
Filed: 1995-01-31
Abstract: PURPOSE: To maintain an etching form excellently, in a semiconductor device in which a silicon nitride film is used as an antireflection film. CONSTITUTION: A silicon nitride film 7 is retreated at least from the side end of a photoresist pattern by a process for isotropically etching the silicon nitride film 7. In this state, by a process for isotropically etching a tungsten silicide film 6, a side wall protecting film 9 is formed so as to reach the surface of the tungsten silicide film 6 from the side end of the photoresist pattern. Etching is performed in the state that the silicon nitride film 7 is covered with the side wall protecting film 9. Thereby generation of nitrogen ions due to the reaction of etching gas with the silicon nitride film 7 is restrained, and it does not occur that nitrogen ions shave the photoresist and the wall protecting film 9, as in the conventional case, so that the etching form can be maintained excellently.

Title: Water measuring method
Inventor: FUJITA KATSUMI
IPC: G01N5/04
Filed: 1989-01-24
Abstract: PURPOSE:To enable speedy drying and to take an accurate measurement in a short time by raising heating temperature up to peak set temperature in the beginning of a drying process, and then lowering the heating temperature gradually to end point set temperature. CONSTITUTION:The heating temperature is raised abruptly up to the set temperature higher than the end point set temperature in the beginning of measurement. During this period, water is present on the surface of a sample and no black burning occurs, so the sample surface is dried speedily. Then the temperature is lowered so that the temperature gradient is constant and slow. Therefore, the temperature is lowered to the sufficiently low end point set temperature when a state wherein the sample is dried and becomes easy to burn black is entered. Thus, the sample is given large heating value and dried in a short time without being burnt black, and the water measurement is speeded up.

Filed: 1991-01-16
Abstract: PURPOSE:To determine the position of a troidal surface accurately and quickly when interference fringes are formed for a measuring part in parallel with any one principal meridian of orthogonally intersecting principal meridians on the troidal surface, the measuring part is scanned along the other principal meridian, and the entire surface is measured. CONSTITUTION:Coherent light emitted from a light source 1 is made to impinge on a reference surface 6a and a troidal surface 7a. The reflected lights are superimposed and received with a convergent lens 13 so that the lights are converged at least at one place. The image of the interference fringes is focused on a bisecting element 15. A knife edge 16 is placed at a convergent point 14 when the troidal surface is located at the regular position. When the troidal surface is shifted from the regular position, the convergent point 14 is moved along the optical axis. A part of the reflected light is interrupted by the knife edge. The amount of the received light on the bisecting element 15 lacks balance, and one side becomes dark. Then, this fact is utilized, and the troidal surface is so moved that the balance is obtained in the bisected element. Then, the troidal surface can be provided at the regular position.
