An airtight tank having a porous bottom plate on which the material is stored is provided for the mixing and blending method.

Pulsating vibration air is introduced into the airtight tank from the bottom of the airtight tank so as to generate air flow going upward through the porous bottom of the airtight tank. As a result, powdered or granular material stored on the porous bottom plate in the airtight tank is uniformly mixed and blended in the airtight tank while continuously moving up and down as in a convectional manner.

Abstract: A Rat IgG antibody film, formed on a p-type Si substrate, is selectively irradiated with ultraviolet rays, thereby leaving part of the Rat IgG antibody film, except for a region deactivated with the ultraviolet rays. Next, when the p-type Si substrate is immersed in a solution containing Au fine particles that have been combined with a Rat IgG antigen, the Rat IgG antigen is selectively combined with the Rat IgG antibody film. As a result, Au fine particles, combined with the Rat IgG antigen, are fixed on the Rat IgG antibody film. Thereafter, the p-type Si substrate is placed within oxygen plasma for 20 minutes, thereby removing the Rat IgG antibody film, the deactivated Rat IgG antibody film and the Rat IgG antigen. Consequently, dot elements can be formed at desired positions on the p-type Si substrate. If these dot elements are used for the floating gate of a semiconductor memory device, then the device has a structure suitable for miniaturization.
