Patent number: 10450669Abstract: A container for silicon ingot fabrication and a manufacturing method thereof are provided. The method includes the following steps. A base layer made of quartz is provided in a chamber. A powder solution layer is coated over an inner surface of the base layer. The powder solution layer includes silicon nitride or carbon. The base layer having the powder solution layer coated thereon is heated to a temperature of 1000° C. to 1700° C. while a reaction gas is supplied into the chamber for 2 hours to 8 hours to form a barrier layer over the inner surface of the base layer. The barrier layer includes silicon oxynitride represented by SixNyOz, 1?x?2, 1?y?2, and 0.1?z?1. Moreover, a method for manufacturing a crystalline silicon ingot is also provided.Type: GrantFiled: June 27, 2017Date of Patent: October 22, 2019Assignee: AUO Crystal CorporationInventors: Chang-Ho Yu, Yen-Ming Chen
