bonding pad 在 Re: [請益] 半導體詢問- 看板Tech_Job 的推薦與評價
※ 引述《misjake (misjake)》之銘言:
: 請問科技版的大大們一個小問題?
: 晶圓測試過程探針與元件接觸的銲墊(pad)就是後段封裝(W/B Technology)中與導線連
: 接所使用的Bond Pad嗎?
: 小弟資質愚鈍來這求解
舉例來說,底下這顆晶片左右有10個焊墊(Pad)。如你說的,這是為了在晶圓測試時,
(CP, chip probing)讓探針與元件有所的接觸,或是之後送包給封裝廠作為打線
(bonding wire)使用。
不過,並非所有的Pad都是作為Bond Pad來使用,因為有些Pad是"Test Pad",
為了某某客戶而作,或是作為開後門使用,這些奇怪功能的Pad在CP 時需要下針,
但在FT(Final Test,送包後的測試)時則不會用到,如下圖的實心方塊,它就會
空在那裡。(為了防止這些接腳電位浮動(floating),通常會有額外的電路將它
拉到weak low或weak high)。
甚至有些是dummy pad(為了混淆敵手 or 防破解用。)
不過基於晶片尺寸考量,可以的話,盡量會減少無用的Pad。

這類的尺寸是依封裝廠的能力而定,從正方形(single bonding pad),例
85um X 85um,或是長方形(double boding pad)例65um X 75um 都有。
(目前有看過50um X 50um)通常不會做太小,一來打線不好弄,二來可能會有應力
殘留問題。
至於推文提到較小尺寸的probing pad,那是為了讓毛針(micro probe)直接在晶圓上
點取訊號、驗證準位是否正確而做的,有十字型,或是口字型...等等。

在臺灣,何謂R&D工程師?
1.Reverse and Decap :IC反向工程,去膠,打開封裝,拍照,複製電路佈局。
2.Resign and Die :沒死的就操到辭職,沒辭職的就操到死。
3.Rework and Debug :計畫永遠跟不上變化,變化永遠跟不上老闆的一句話!
4.Relax and Delay :太過於輕鬆(Relax),那麼就要有schedule delay的準備!
但是外派到大陸的臺灣郎,晚上是R (鴨)陪客戶,白天是D (豬)任人宰割!
