5月29日,国内首批产业化6英寸碳化硅外延晶片在位于厦门火炬高新区的瀚天天成电子科技(厦门)有限公司投产,并交付第一笔商业订单产品,成为国内首家提供商业化6英寸碳化硅外延晶片的生产商。瀚天天成电子科技(厦门)有限公司总经理郑忠惠介绍,6英寸碳化硅外延晶片相对于4英寸碳化硅外延晶片具有巨大的成本优势。以2×2mm2尺寸的管芯制作为例,4英寸碳化硅外延晶片只可产出1625个管芯,而6英寸外延晶
On May 29, the first batch of industrialized 6-inch SiC epitaxial wafers in China was put into operation at Hantian Tiancheng Electronic Technology (Xiamen) Co., Ltd. in Xiamen Torch Hi-tech Zone and delivered its first commercial order products, making it the first commercial supplier in China Manufacturers of 6-inch silicon carbide epitaxial wafers. Han Zhong Tian Cheng Electronic Technology (Xiamen) Co., Ltd. General Manager Zheng Zhonghui introduced 6-inch silicon carbide epitaxial wafer relative to 4-inch silicon carbide epitaxial wafer has a huge cost advantage. Taking a 2 × 2 mm2 die for example, a 4-inch silicon carbide epitaxial wafer can yield only 1625 dies and a 6-inch epitaxial wafer
