WebFeb 15, 2024 · For comparison purposes, the oxide surface was tested using DHF spray chemistry. The surface roughness was not significantly affected by the DHF spray for either silicon nitride or poly Si layers. This was true for APM chemistry as well. However, oxide layers showed a high roughness of 10.4 nm after treatment with DHF spray.

Dihydrofolic acid (conjugate base dihydrofolate) (DHF) is a folic acid (vitamin B9) derivative which is converted to tetrahydrofolic acid by dihydrofolate reductase. Since tetrahydrofolate is needed to make both purines and pyrimidines, which are building blocks of DNA and RNA, dihydrofolate reductase is targeted by various drugs to prevent nucleic acid synthesis.
