Title: Formation of si3n4 film and mis semiconductor element
Inventor: SHIOGAMA HIROAKI
IPC: H01L21/336
Filed: 1995-06-16
Abstract: PURPOSE: To provide a method for forming an Si3 N4 film which can suppress a reduction in the Si3 N4 film when a resist film is removed by hot dilute sulfuric acid. CONSTITUTION: An SiO2 film 14 is formed by normal thermal oxidation on a semiconductor substrate 10, and a window is opened on the SiO2 film 14 to provide an electrode forming region. An SiN4 film 18 is formed on the entire substrate 10 face by means of CVD under normal conditions to obtain a thickness of 50nm. After the Si3 N4 film 18 is formed on the substrate 10, a plasma asher is used to perform oxygen plasma processing for oxidizing the surface of the Si3 N4 film to form an ultra-thin SiO2 film 20 having a thickness of 1nm or less. A mask pattern 22 of photoresist is used to etch the Si3 N4 film 18 having the thin SiO2 film on the surface by means of normal photolithographic technology. Finally the photoresist of the mask pattern 22 is cleaned and removed by hot dilute sulfuric acid from 120 to 140 deg.C.

Title: Method for controlling pouring robot
Inventor: KAMIYA HISANORI
IPC: B22D37/00
Filed: 1993-07-16
Abstract: PURPOSE:To prevent overpouring and to execute adequate pouring even in a pouring operation by a robot by inputting a displacement difference between a sand mold level and a liquid level into the robot and determining the pouring speed meeting this displacement difference by the computation of the robot. CONSTITUTION:The level displacement difference 1 is taken as data into the robot which computes the pouring speed by this data and executes adaptive control to enable adequate pouring. Not resetting of a handle after the level displacement difference 1 attains 0 but resetting of the hand as the level difference decreases while observing the level displacement difference 1 at all times leads to shortening of the tact time of the robot hand. The extremely little pouring is just executed at the liquid level near the sand mold level. The overpouring is thus averted and the optimum pouring is possible.
