Title: Formation of hetero interface
Inventor: ANAMI TAKAYOSHI
IPC: H01L21/338
Filed: 1987-09-25
Abstract: PURPOSE:To prevent adhesion of impurities during a waiting phase and to prevent deterioration in light-emitting efficiency, by applying molecular beams to form a first epitaxial layer and then applying electronic beams to flatten the surface in the waiting phase. CONSTITUTION:At least one type of first molecular beams are applied to a substrate held at a predetermined temperature so that first molecules or atoms are deposited thereon to form a first epitaxial layer. In the waiting phase, application of the first molecular beams is stopped temporarily and electronic beams are applied to the first epitaxial layer. Application of the electronic beams is stopped and the first molecular beams are applied again so that the first molecules or atoms are deposited in one to several molecular or atomic layers to form a second epitaxial layer. At least one kind of second molecular beams are applied to the second epitaxial layer so that second molecules or atoms are deposited to form a third epitaxial layer. By applying the electronic beams to the substrate surface in the waiting phase at the homojunction interface, the surface diffusing rate of the atoms can be increased to decrease incorporation of impurities at the homo interface.

Abstract: PURPOSE:To accurately read '0', '1' data from a memory cell by stabilizing a reference potential to be obtained based on a dummy cell. CONSTITUTION:Electrons are previously extracted from a floating gate of a dummy cell DC by an erasing circuit EC. A bias is applied from a data line bias circuit DBC to a memory cell C selected by a selector (row decoder RD, a column decoder CD). A detection signal VSA from the bias circuit DBC is output as a different value according to whether its current flows or not. A bias is applied from the circuit DBC to the cell DC, and a current flows to the cell DC. A reference voltage VREF responsive thereto is output from a dummy data bias circuit DDC as a stable value. The two voltages VSA, VREF are compared by comparing means (differential amplifier SA), and storage data of the selected cell C is detected.
