Abstract:
PURPOSE: A semiconductor device is provided to prevent the collapse of lower electrodes by providing a supporting structure between the lower electrodes. CONSTITUTION: A supporting structure includes a supporter(33S) and a glue layer(41) between metal patterns. The metal pattern has a vertical length longer than a horizontal length on a substrate. The supporter has band gap energy of 4.5eV or greater. The glue layer is touched with the metal patterns. The supporter and the glue layer are made of different film materials.
Abstract:
PURPOSE: A semiconductor device and a method for manufacturing the same are provided to reduce a current leakage by forming an insertion layer between a dielectric layer and an upper metal layer. CONSTITUTION: A lower metal layer(14), a dielectric layer(18), and an upper metal layer are successively formed on the upper side of a semiconductor substrate. Insertion layers(16a) are formed in a first part between the lower metal layer and the dielectric layer, a second part between the dielectric layer and the upper metal layer, or both of the first part and the second part. The dielectric layer is composed of a metal oxide film. The insertion layers are composed of a metal material film.

Abstract:
A method of synthesizing ligands for a BST precursor is provided to improve the yield and selectivity of a ligand for a barium strontium titanate precursor while reducing the reaction time. A method of synthesizing ligands for a BST precursor comprises (S1) a step for manufacturing a mixture including beta - die ketone indicated as the chemical formula 1 and a primary amine indicated as R3NH2; and (S2) a step for irradiating the microwave to the mixture. In the chemical formula 1, R1, R2 and R3 are C1-8 linear or branched alkyl group, alkyl fluoride group or aryl group.
