Filed: 1992-12-10
Abstract: PURPOSE: To provide an image reproducing method and device which can surely process land data with higher calculation efficiency. CONSTITUTION: In order to reproduce an image by a computer tomographic method in conformity with the whole shape of a body 24 irradiated by a cone beam source 26, only necessary cone beam projection data collected along a three-dimensional scanning track are left. In the case of such a scanning track that a set of complete land data is originally collected, the image which is thus reproduced is accurate. The image reproducing process is limited to only a support area in the land space that the body 24 itself occupies. Consequently, approximation of calculation conforming with the whole shape of the body 24 is applied.

Title: Cleaning method for substrate
Inventor: TAKAHARA YOICHI
IPC: G03F1/82
Filed: 1991-12-13
Abstract: PURPOSE:To obtain a new method for cleaning a substrate by cleaning and eliminating efficiently a foreign object of fine grains having a fine diameter, which have not been eliminated satisfactorily in a conventional method. CONSTITUTION:As the figure shows, the condition for bonding a foreign object to a semiconductor substrate is such that the relation between a grain diameter of the foreign object and bonding energy form a direct line in case of the diameter of less than 0.1mum. It was testified that, as a diameter of a grain increases, bonding energy also increases, and the diameter of a grain reduces, bonding energy also reduces. Therefore, a foreign object of a fine grain on a semiconductor substrate can be eliminated from the substrate by reducing the bonding energy, or supplying greater outside energy than the bonding energy. To reduce the bonding energy, there is a method of breaking a foreign object into fine pieces by irradiating laser beam on it. To supply energy, there is a method of heating a foreign object in cleaning liquid.
