课程说明及重点
高压制程电子产品一般大的可靠性问题是静电放电(ESD) 很差、闩锁(LU)能力也很差,而且模拟高压电路输出端口又会占很大面积,这会影响使其ESD能力通常非常不佳。ESD)/LU破坏是影响IC可靠性的重要因素也是延缓产品上市的主因,因此无论由制程上、设计上全方位的防护措施是必要的。本课程是高压集成IC
ESD/LU防护设计上之实务课程,更是各高压集成IC产品ESD可靠度防护上热门的技术。
本课程将从各种HV CMOS元器件、晶圆厂技术平台、HV组件的汲极工程、高压元器件ESD/LU能力如何测试介绍起,进而谈论HV
CMOS 的各电性、可靠度缺点、晶圆厂HV ESD/LU 防护设计法则及各种ESD/LU保护策略及如何保护HV
LDMOS与HV 集成电路ESD/LU防护实际案例分析,后期许学员能对HV制程工艺及组件结构充分理解,并熟悉HV
IC静电防护及LU免疫设计之防制意义。
授课对象
现职从事模拟IC与电子产品之RD设计、布局、制造、产品应用与品管、品保、FA相关技术人员 (对ESD/LU防护已有认识者)。
