Abstract: This article summarizes, analyzes, and interprets the main testing standards for electrostatic discharge of device level charged device models (CDM) both domestically and internationally. The differences and correlations between various standards were sorted out, and the application scope and technical points of each standard were clarified. The impact factors and control methods that affect the testing results of device level charged device models (CDM) were deeply studied. Relevant technical skills were proposed to ensure the consistency and accuracy of test results in the standard application process, providing guidance for the selection, testing, and engineering application of device level charged device model testing standards.
Key words : charged device model;device level;test standard

引言

半導(dǎo)體器件在制造、測試、試驗(yàn)、裝配、運(yùn)輸及貯存過程中受外在電場作用,或與其他絕緣材料相互摩擦作用,使器件內(nèi)部積聚大量電荷,與接地導(dǎo)體接觸后形成導(dǎo)電通道,大量電荷向外部傳導(dǎo),并極短的時(shí)間內(nèi)產(chǎn)生靜電脈沖,導(dǎo)致器件損壞,該失效機(jī)制就是器件級(jí)帶電器件模型(CDM)靜電放電(簡稱CDM ESD)現(xiàn)象 [1-2]。

半導(dǎo)體制造工藝節(jié)點(diǎn)的提升和結(jié)構(gòu)的變化,尤其是柵氧層厚度的降低,嚴(yán)重影響了元器件對(duì)CDM ESD的耐受能力,使CDM ESD測試考核逐步成為新產(chǎn)品性能考核的必需項(xiàng)。目前,國內(nèi)各領(lǐng)域針對(duì)CDM ESD測試標(biāo)準(zhǔn)建設(shè)還不完善,基本上都是參照國際相關(guān)標(biāo)準(zhǔn)進(jìn)行考核,執(zhí)行標(biāo)準(zhǔn)的差異與對(duì)相關(guān)國際標(biāo)準(zhǔn)的范圍、執(zhí)行要求以及應(yīng)用范圍等認(rèn)識(shí)不夠清晰,造成了測試標(biāo)準(zhǔn)的選擇、測試和工程應(yīng)用過程中諸多問題產(chǎn)生[3]。

本文對(duì)CDM國內(nèi)外相關(guān)通用測試標(biāo)準(zhǔn)進(jìn)行整理、分析與解讀。梳理各標(biāo)準(zhǔn)之間差異性和關(guān)聯(lián)性,明確各標(biāo)準(zhǔn)的應(yīng)用范圍與技術(shù)要點(diǎn),研究并分析影響器件級(jí)CDM ESD測試結(jié)果的因素與相應(yīng)控制方法,并提出標(biāo)準(zhǔn)應(yīng)用過程中一些技術(shù)技巧,用于保障結(jié)果一致性和準(zhǔn)確性,指導(dǎo)器件級(jí)CDM ESD測試標(biāo)準(zhǔn)的選擇、測試和工程應(yīng)用。
