Title: Semiconductor memory device provided with quantum structure
Inventor: HIROSE ZENKO
IPC: H01L29/788
Filed: 1997-09-12
Abstract: PROBLEM TO BE SOLVED: To enable a semiconductor memory device to be uniform in threshold and to operate stably at high speed on a low voltage by a method wherein a quantum structure composed of many conductive materials is arranged in a two-dimensional manner to form a floating gate. SOLUTION: Silicon quantum structures or silicon quantum dots 4 each smaller than 10 nm are arranged in a two-dimensional manner to form a polycrystalline silicon floating gate which serves as a charge storage layer. An insulating film 3 interposed between the quantum dots 4 and a substrate is formed so thin as to enable electrons to tunnel through it. The insulating film 3 is set thicker at a control gate side than at a substrate side so as to capture the injected electrons in the quantum dots 4.  Therefore, the electrical charge injected into each of the quantum structures is limited to an amount of charge integer times as large as an elemental electrical charge due to a quantum-mechanical effect, and the injection of charge is induced only at a specific voltage due to a so-called Coulomb blockade effect, so that a semiconductor memory device of this constitution can be markedly lessened in the dispersion of threshold voltage which features its memory function.

Title: Anisotropic conductive material, anisotropic adhesive, electrically connecting method of the adhesive applied electrode, and electric circuit substrate formed thereby
Inventor: KOMATSU MICHIO
IPC: H01B1/20
Filed: 1989-09-26
Abstract: PURPOSE:To electrically connect electrodes at an excellent insulation rate between adjacent electrodes and at an excellent vertical conductive rate by applying pressure to anisotropic conductive material, where an insulating grain is attached to the surface of a conductive grain, placed between electrodes opposed to each other. CONSTITUTION:A substrate 2 having an electrode 1 and an IC chip 4 having an electrode 3 are made to be opposed to each other so that anisotropic conductive adhesive is placed between the respective electrodes by means of printing or coating, and thereafter, the insulating grains in the adhesive are pressed to such an extent that the conductive grains 5 attached to the surface thereof are diffused in a signal layer. If this pressure is continuously applied or again applied, the insulating grains attached to the sides of both the electrodes of conductive grains are removed from the conductive grains with the result that the upper and lower portions of the conductive grain come into contact with both the electrodes and the electrodes are electrically connected. If the adhesive is heated or an electromagnetic wave is radiated to the adhesive while the condition of pressure application is kept, the adhesive compound 6 is hardened and shrinked and the conductive grains are stressed, so that the IC chip electrode 3 and the electrode 1 of the substrate become conductive and are closely adhered.
