antenna diode
如下圖，而第二張圖也提醒了一下，不是向上跳一層就可以解決，也有可能第二層也太長，那只好一直向上跳囉。 第二個方法是加一個放電的路徑給它，加個Diode(通常被叫antenna diode)，當然有好有壞平常會不會偷偷漏電呢？我不知道，而且並不是一定加一顆就解決，也許會不夠大，不過至少我還沒遇到，呵呵。,,If the diode is connected to metal near the gate(s), it can protect the gate oxide. This can be done only on nets with violations, or on every gate (in general by putting such diodes in every library cell). The "every cell" solution can fix almo,因此，若在驗證完antenna rule 後，發現此. 佈局有可能產生天線效應，其解決方法有二：(1) 將金屬層分段，做跳線的動作，如：M1- via12- M2- via23- M3- via23- M2- via12- M1，而不是全部使用Metal1；(2) 在poly gate連接出來的. 金屬線，加上N+/P-Sub或P+/N-Well二極體(diode)，提供累積在金屬層的電荷一條路徑釋放電. 荷，而不會 ... , DESIGN MANUAL 應該有寫.這裡提出小小的看法提供您參考./ ~5 ?5 Y, R# I6 F# M 1.加diode可以,但是要注意比例問題,有時候要加很多個diode在gate端2 D! j, m; } |# |* j 另外,需要match/critical的mos也會加diode. - -3 r4 i. -, n2.跳線也行,but別亂跳!假設跳到上層metal,之後又用該層拉線,會沒問題嗎?, Could you please explain to me why you need antenna didoes: 1.
