「半(ban)導(dao)體后工程第(di)yi一篇」半(ban)導(dao)體測試的理(li)解（1/11）

半(ban)導體(ti)工(gong)(gong)(gong)藝分為(wei)(wei)制(zhi)(zhi)(zhi)(zhi)(zhi)造(zao)晶(jing)(jing)(jing)(jing)片(pian)(pian)和(he)(he)刻錄電路的前(qian)工(gong)(gong)(gong)程(cheng)、封(feng)裝(zhuang)芯片(pian)(pian)的后(hou)工(gong)(gong)(gong)程(cheng)。兩個工(gong)(gong)(gong)程(cheng)里后(hou)工(gong)(gong)(gong)程(cheng)在半(ban)導體(ti)細微(wei)化技術逼近臨(lin)界點的當下，重(zhong)(zhong)要(yao)性越來越大(da)。特別是(shi)作為(wei)(wei)能夠創造(zao)新的附加價值(zhi)的核he心(xin)技術而備(bei)受關注，往后(hou)總共分成十一(yi)(yi)章節跟大(da)家一(yi)(yi)起分享。1.半(ban)導體(ti)后(hou)工(gong)(gong)(gong)序(xu)為(wei)(wei)了制(zhi)(zhi)(zhi)(zhi)(zhi)造(zao)半(ban)導體(ti)產品(pin)，首先要(yao)設(she)計(ji)芯片(pian)(pian)（chip），使其能夠實(shi)現想要(yao)的功能。然后(hou)要(yao)把設(she)計(ji)好的芯片(pian)(pian)制(zhi)(zhi)(zhi)(zhi)(zhi)作成晶(jing)(jing)(jing)(jing)圓(yuan)（wafer）形式。晶(jing)(jing)(jing)(jing)圓(yuan)由芯片(pian)(pian)重(zhong)(zhong)復排(pai)列組成，仔細觀看完工(gong)(gong)(gong)后(hou)的晶(jing)(jing)(jing)(jing)圓(yuan)是(shi)網格(ge)形狀。一(yi)(yi)格(ge)就是(shi)一(yi)(yi)個芯片(pian)(pian)。芯片(pian)(pian)尺(chi)寸(cun)(cun)大(da)，一(yi)(yi)個晶(jing)(jing)(jing)(jing)圓(yuan)上所制(zhi)(zhi)(zhi)(zhi)(zhi)造(zao)的芯片(pian)(pian)數量(liang)少(shao)，反之(zhi)芯片(pian)(pian)尺(chi)寸(cun)(cun)數量(liang)就多。半(ban)導體(ti)設(she)計(ji)不屬(shu)于(yu)制(zhi)(zhi)(zhi)(zhi)(zhi)造(zao)工(gong)(gong)(gong)藝，所以簡述半(ban)導體(ti)制(zhi)(zhi)(zhi)(zhi)(zhi)造(zao)工(gong)(gong)(gong)藝的話，依(yi)次是(shi)晶(jing)(jing)(jing)(jing)片(pian)(pian)工(gong)(gong)(gong)藝、封(feng)裝(zhuang)工(gong)(gong)(gong)藝和(he)(he)測試。因此半(ban)導體(ti)制(zhi)(zhi)(zhi)(zhi)(zhi)造(zao)的前(qian)端(duan)(duan)（Front End）工(gong)(gong)(gong)序(xu)是(shi)晶(jing)(jing)(jing)(jing)圓(yuan)制(zhi)(zhi)(zhi)(zhi)(zhi)造(zao)工(gong)(gong)(gong)序(xu)，后(hou)端(duan)(duan)（Back End）工(gong)(gong)(gong)序(xu)是(shi)封(feng)裝(zhuang)和(he)(he)測試工(gong)(gong)(gong)序(xu)。在晶(jing)(jing)(jing)(jing)圓(yuan)制(zhi)(zhi)(zhi)(zhi)(zhi)造(zao)工(gong)(gong)(gong)藝內(nei)(nei)也區(qu)分前(qian)端(duan)(duan)、后(hou)端(duan)(duan)，在晶(jing)(jing)(jing)(jing)圓(yuan)制(zhi)(zhi)(zhi)(zhi)(zhi)造(zao)工(gong)(gong)(gong)藝內(nei)(nei)，前(qian)端(duan)(duan)通常是(shi)指CMOS制(zhi)(zhi)(zhi)(zhi)(zhi)程(cheng)工(gong)(gong)(gong)序(xu)，后(hou)端(duan)(duan)是(shi)金(jin)屬(shu)布線(xian)工(gong)(gong)(gong)序(xu)。

測試芯片需要哪些東西，分(fen)別有什么作用？

測(ce)(ce)(ce)試(shi)芯片(pian)通常需要以下幾(ji)個要素：1、芯片(pian)測(ce)(ce)(ce)試(shi)設備(bei)：芯片(pian)測(ce)(ce)(ce)試(shi)設備(bei)是用于對芯片(pian)進行電氣性能(neng)、功能(neng)和可(ke)靠性等(deng)(deng)方(fang)面的測(ce)(ce)(ce)試(shi)的專zhuan用設備(bei)。它通常包括測(ce)(ce)(ce)試(shi)儀器、測(ce)(ce)(ce)試(shi)軟件和測(ce)(ce)(ce)試(shi)算法等(deng)(deng)組(zu)成部分。測(ce)(ce)(ce)試(shi)設備(bei)提(ti)供了電信號的生成、測(ce)(ce)(ce)量(liang)和分析功能(neng)，以評估芯片(pian)的性能(neng)和功能(neng)是否符合規(gui)格要求。

2、芯片(pian)測(ce)(ce)試(shi)底座(zuo)：芯片(pian)測(ce)(ce)試(shi)底座(zuo)是用于(yu)安(an)裝(zhuang)和(he)(he)連(lian)接芯片(pian)到測(ce)(ce)試(shi)設備(bei)的(de)接口裝(zhuang)置，如前面所提到的(de)。它(ta)提供了芯片(pian)與測(ce)(ce)試(shi)設備(bei)之(zhi)間的(de)電氣連(lian)接和(he)(he)信(xin)號傳輸，確(que)保準確(que)和(he)(he)可重復的(de)測(ce)(ce)試(shi)結果(guo)。扇(shan)入型WLCSP工藝將導(dao)線和(he)(he)錫(xi)球固定在晶(jing)圓頂部，而(er)扇(shan)出型WLCSP則將芯片(pian)重新排列為模塑晶(jing)圓。

三維堆疊半(ban)導(dao)體(ti)(ti)(ti)（stacking）技(ji)術(shu)(shu)是半(ban)導(dao)體(ti)(ti)(ti)封(feng)(feng)(feng)裝(zhuang)(zhuang)技(ji)術(shu)(shu)領域變革性(xing)發(fa)展(zhan)(zhan)。過去半(ban)導(dao)體(ti)(ti)(ti)封(feng)(feng)(feng)裝(zhuang)(zhuang)只(zhi)能(neng)裝(zhuang)(zhuang)一(yi)個(ge)芯(xin)片，現在(zai)已(yi)經(jing)開(kai)發(fa)出了(le)多(duo)芯(xin)片封(feng)(feng)(feng)裝(zhuang)(zhuang)（Multichip package）、系統及封(feng)(feng)(feng)裝(zhuang)(zhuang)（System in Package）等技(ji)術(shu)(shu)，在(zai)一(yi)個(ge)封(feng)(feng)(feng)裝(zhuang)(zhuang)殼(ke)中加入多(duo)個(ge)芯(xin)片。封(feng)(feng)(feng)裝(zhuang)(zhuang)技(ji)術(shu)(shu)還呈(cheng)現半(ban)導(dao)體(ti)(ti)(ti)器件小(xiao)型(xing)化的(de)(de)發(fa)展(zhan)(zhan)趨勢，即縮小(xiao)產品(pin)(pin)(pin)(pin)尺(chi)寸(cun)。隨著半(ban)導(dao)體(ti)(ti)(ti)產品(pin)(pin)(pin)(pin)逐(zhu)漸(jian)被用(yong)(yong)(yong)于移動甚至可穿戴產品(pin)(pin)(pin)(pin)，小(xiao)型(xing)化成(cheng)為客(ke)戶的(de)(de)一(yi)項重(zhong)要(yao)需求。為了(le)滿足這(zhe)一(yi)需求，許多(duo)旨在(zai)減(jian)小(xiao)封(feng)(feng)(feng)裝(zhuang)(zhuang)尺(chi)寸(cun)的(de)(de)技(ji)術(shu)(shu)隨之(zhi)而誕生。半(ban)導(dao)體(ti)(ti)(ti)產品(pin)(pin)(pin)(pin)被越來越多(duo)地應用(yong)(yong)(yong)在(zai)不(bu)(bu)同(tong)的(de)(de)環境中。它(ta)不(bu)(bu)僅(jin)在(zai)日常環境中使(shi)(shi)用(yong)(yong)(yong)，還在(zai)雨林、極地、深海和太空中使(shi)(shi)用(yong)(yong)(yong)。由于封(feng)(feng)(feng)裝(zhuang)(zhuang)的(de)(de)基本作(zuo)(zuo)用(yong)(yong)(yong)是芯(xin)片/器件的(de)(de)保(bao)護（protection），因此(ci)必須(xu)開(kai)發(fa)出高可靠性(xing)（Reliability）的(de)(de)封(feng)(feng)(feng)裝(zhuang)(zhuang)技(ji)術(shu)(shu)，以(yi)使(shi)(shi)半(ban)導(dao)體(ti)(ti)(ti)產品(pin)(pin)(pin)(pin)在(zai)這(zhe)種不(bu)(bu)同(tong)的(de)(de)環境下也能(neng)正常工作(zuo)(zuo)。同(tong)時，半(ban)導(dao)體(ti)(ti)(ti)封(feng)(feng)(feng)裝(zhuang)(zhuang)是蕞終產品(pin)(pin)(pin)(pin)，因此(ci)封(feng)(feng)(feng)裝(zhuang)(zhuang)技(ji)術(shu)(shu)不(bu)(bu)僅(jin)要(yao)發(fa)揮所需功(gong)能(neng)，又能(neng)降低di,制造 費用(yong)(yong)(yong)的(de)(de)技(ji)術(shu)(shu)非常重(zhong)要(yao)。不(bu)(bu)同(tong)于引線(xian)框(kuang)架封(feng)(feng)(feng)裝(zhuang)(zhuang)只(zhi)有一(yi)個(ge)金(jin)(jin)屬(shu)布(bu)線(xian)層（因為引線(xian)框(kuang)架這(zhe)種金(jin)(jin)屬(shu)板無法形成(cheng)兩個(ge)以(yi)上金(jin)(jin)屬(shu)層）.松(song)江區78FBGA-0.8P導(dao)電膠發(fa)展(zhan)(zhan)現狀

維修(Repair)修復(fu)是(shi)主要在存儲(chu)半導體(ti)中執行(xing)的(de)(de)(de)工(gong)序，多余(yu)(yu)的(de)(de)(de)單(dan)元(yuan)代替不(bu)(bu)良(liang)單(dan)元(yuan)的(de)(de)(de)修復(fu)算法（Repair Algorithm）。例如(ru)，如(ru)果DRAM 256bit內存的(de)(de)(de)晶片(pian)測(ce)試結果顯示(shi)有1bit不(bu)(bu)合(he)格(ge)，那么這款(kuan)產品就(jiu)(jiu)是(shi)255bit。但當多余(yu)(yu)的(de)(de)(de)單(dan)元(yuan)取代劣質(zhi)單(dan)元(yuan)后，又成(cheng)為滿(man)足256bit并可(ke)銷售給(gei)客戶的(de)(de)(de)良(liang)品。通過修復(fu)，蕞終提高了(le)產量。因此(ci)(ci)，存儲(chu)芯片(pian)在設計時會產生多余(yu)(yu)的(de)(de)(de)單(dan)元(yuan)，以便根據測(ce)試結果進(jin)行(xing)替代。但是(shi)為了(le)應(ying)對不(bu)(bu)良(liang)現象(xiang)，制(zhi)作多余(yu)(yu)的(de)(de)(de)單(dan)元(yuan)就(jiu)(jiu)會占(zhan)用空間，增加芯片(pian)的(de)(de)(de)大(da)小。因此(ci)(ci)，不(bu)(bu)可(ke)能(neng)(neng)產生很多的(de)(de)(de)單(dan)元(yuan)格(ge)。因此(ci)(ci)考(kao)慮(lv)工(gong)藝能(neng)(neng)力，制(zhi)作出能(neng)(neng)蕞da程度(du)體(ti)現良(liang)率增加效(xiao)果的(de)(de)(de)多余(yu)(yu)單(dan)元(yuan)。也就(jiu)(jiu)是(shi)說如(ru)果工(gong)藝能(neng)(neng)力好，劣質(zhi)少(shao)，就(jiu)(jiu)可(ke)以少(shao)做(zuo)(zuo)多余(yu)(yu)的(de)(de)(de)單(dan)元(yuan)，如(ru)果工(gong)藝能(neng)(neng)力不(bu)(bu)好，預計劣質(zhi)多，就(jiu)(jiu)會多做(zuo)(zuo)多余(yu)(yu)的(de)(de)(de)單(dan)元(yuan)。黃浦(pu)區芯片(pian)測(ce)試導電膠零售價
