Description

technical field [0001] The invention belongs to the technical field of alloys, and in particular relates to an aluminum material alloy, a preparation method and uses thereof. Background technique [0002] Chemical vapor deposition is one of the core processes in the production process of integrated circuits. It has significant advantages in film formation uniformity, compactness and coverage. In the production process of large-scale integrated circuits, the dielectric film layer, conductive material And semiconducting materials, including a wide range of insulating material films, are almost all completed by chemical vapor deposition. With the innovation of technology, in order to achieve atomic-level film thickness control, chemical vapor deposition methods are in the reaction rate controllability and film thickness. Uniformity is very competitive. [0003] The basic principle of chemical vapor deposition process: two or more gaseous raw materials are introduced into the g...
