Hi all,
We have problems removing our 1.2 micron i line resist after
etching 1 micron of polysilicon (bright field mask).
In our recipe we use a combination of HBr and Cl to get a nice
endpoint when we hit the oxide/nitride under the polysilicon.
The resist after etching looks normal.
We have tried oxygen plasma, pirahna and can't seem to get a
nice and complete strip of the resist.
Anyone with any solution to this problem? Thanks
Regards
Yan
