What is recipe of patterning mask using PMMA over SOI? Can anyone share some research article to etch Si using RIE?

I have 250 nm (top silicon over oxide) thick SOI. I want to create slot of 200 nm width and 250 nm height. What is recipe of patterning mask using EBL over the SOI? Will it be better to use PMMA...
