Dear all,
I have a question. I use tmsc 0.18µm. I use miminum width of 0.22µm and length of 0.18µm. Can this one be draw in layout? Because it must use contact.
But contact's width and length are longer than my mos. It may be errors.
Thanks. If you know,please tell me.
My question is w=0.22u and but contact must be 0.4u*0.4u.
If my width is smaller contact. It's will be errors.
How do I layout and not to change size.
Thanks.
This kind of MOS are know as "mos smaller than the contact head".
Compare to a mos which = or bigger than the contact head you will need the rule SPACING_ACTIVE_POLY. Draw ACTIVE like a bone with your desired witdh in the middle and add one contact on each side. Then the SPACING_ACTIVE_POLY (in fact SPACING_ACTIVE_POLY) will define your minimal drawing.

????????????????????????
Could you explain me what you are doing because I'm a little bit scared (I mean for you) by your 2 last questions?
BLUE = ACTIVE AREA or if you want DIFFUSION or DIFF or THOX ...
There is also a implant or implantation ... layer which enclose the diffusion which will define the type of your MOS (in white on the picture!!!).
... and the mos is define by the intersection of the poly and the active area ... in your case 220 by 180 to come back to the first question...
Yes and so ...
That has nothing to do with the initial question.
What was the point of this remark please?
Anyway is it clear for you now ilter? That would be great to have an answer from you.
