電子特氣系統(tǒng)在半導(dǎo)體制程擴(kuò)散工藝中的應(yīng)用
?在半導(dǎo)體制造中，擴(kuò)散工藝是一種常用的生產(chǎn)工藝，是一種摻雜技術(shù)，而電子特氣系統(tǒng)是能將擴(kuò)散工藝所需的元素氣體原材料，在保護(hù)氣體純度的同時(shí)，安全穩(wěn)定的供應(yīng)到使用設(shè)備。
?
?什么是擴(kuò)散工藝？
?
擴(kuò)散工藝是一種摻雜技術(shù)，在高溫條件下，利用熱擴(kuò)散原理將雜質(zhì)元素按工藝要求對(duì)半導(dǎo)體晶圓進(jìn)行摻雜，即將元素磷、硼擴(kuò)散入硅襯底中，從而改變和控制半導(dǎo)體內(nèi)雜質(zhì)的類型、濃度和分布，改變硅材料的電學(xué)特性，以便建立起不同的電特性區(qū)域。
?
擴(kuò)散工藝在半導(dǎo)體制造中應(yīng)用主要體現(xiàn)在對(duì)關(guān)鍵結(jié)構(gòu)PN結(jié)形成的作用上。因?yàn)閱为?dú)的擴(kuò)散工藝還有一些缺陷：如高溫?cái)U(kuò)散時(shí)間長(zhǎng)、生產(chǎn)周期長(zhǎng)、所需溫度高等，這些缺陷會(huì)對(duì)半導(dǎo)體的產(chǎn)量、質(zhì)量和成品率等都會(huì)造成影響，所以，在PN結(jié)的制造中，擴(kuò)散工藝常搭配離子注入技術(shù)一起使用。
?
??特氣系統(tǒng)的應(yīng)用：
?
在半導(dǎo)體制造中，特氣系統(tǒng)將含元素離子氣體作為摻雜氣體注入到晶圓表面，通過(guò)擴(kuò)散原理改變硅材料的電學(xué)特性，形成半導(dǎo)體PN結(jié)。
?
半導(dǎo)體行業(yè)對(duì)所用的氣體，不管是純度還是氣體性質(zhì)都有著使用要求，被稱為電子特氣，大多數(shù)是易燃易爆、劇毒、腐蝕性的特殊氣體，具有很大的危險(xiǎn)性。超高純電子特氣系統(tǒng)，就是在保護(hù)電子特氣純度、避免外界雜質(zhì)污染的同時(shí)，保證氣體的使用安全、壓力穩(wěn)定和使用設(shè)備的精準(zhǔn)供氣。
