Actually, you had already answered my question. My original question is :
If I using the jumper method to solve the antenna effect on metal_1, that is, I seperate the charges on metal_1 by segmenting metal_1. And it works only during metal_1 etching. If the charges by metal_1 etching aren't be...
Thank your reply.
Are the charges in the above that you mentioned caused by metal_2 etching?
My question is focus on the charges by metal_1 etching. Where do the charges go?
Aren't they flushed before metal_2 etching?
Or you just want to emphasize that the antenna effect on top metal should be...
Thank Kapilsn's reply~
I finished studying all the messages and I gained a lot.
So the answer is :
The accumulated charges was flushed in the "wet cleaning" step before fabricating the next metal level.
If I am wrong, please correct me.
Thank you very much~
Hi, dear all :
If i had antenna violation at metal 1, then i segment metal 1 into several parts.
And using the jmpers to connect them. This is a solution for antenna effect.
My question is :
When the metal 2 is fabricated, does the accumulated charges in different parts of metal 1 will convene...

Depending on my research during these days,
here I sum up the method to break the feedback loop for analysis of loop gain:
1. If the ac source is voltage, then breaks the high impedance node;
__If the ac source is current, then break the low impedance node.
2. Use the low pass filter to break...
* As node C will be your input for loop gain simulation there is nothing to add.
* If you know the load, connect it to node B. Or use a replica of the path which you have disconnected. However, don´t forget that the dc loop has also been broken with the consequence of probable bias problems...
Dear all:
Now I want to use Hspice to analyze the stability of a feedback loop .
Then, in a feedback loop, if I break a node A into B and C, how should I add the loadings on node B and node C ?
Thank your replies.
