課程說明及重點

高壓制程電子產(chǎn)品一般最大的可靠性問題是靜電放電(ESD) 很差、閂鎖(LU)能力也很差，而且模擬高壓電路輸出端口又會占很大面積，這會影響使其ESD能力通常非常不佳。ESD)/LU破壞是影響IC可靠性的重要因素也是延緩產(chǎn)品上市的主因，因此無論由制程上、設(shè)計上全方位的防護措施是必要的。本課程是高壓集成IC ESD/LU防護設(shè)計上之實務(wù)課程，更是各高壓集成IC產(chǎn)品ESD可靠度防護上最熱門的技術(shù)。

本課程將從各種HV CMOS元器件、晶圓廠技術(shù)平臺、HV組件的汲極工程、高壓元器件ESD/LU能力如何測試介紹起，進而談?wù)揌V CMOS 的各電性、可靠度缺點、晶圓廠HV ESD/LU 防護設(shè)計法則及各種ESD/LU保護策略及如何保護HV LDMOS與HV 集成電路ESD/LU防護實際案例分析，最后期許學(xué)員能對HV制程工藝及組件結(jié)構(gòu)充分理解，并熟悉HV IC靜電防護及LU免疫設(shè)計之防制意義。

授課對象

現(xiàn)職從事模擬IC與電子產(chǎn)品之RD設(shè)計、布局、制造、產(chǎn)品應(yīng)用與品管、品保、FA相關(guān)技術(shù)人員 (對ESD/LU防護已有認識者)。
