Etching Block Copolymer Directed Self-Assembly Holes

Project Type: 
March 2019
Areas of Interest: 
Directed Self Assembly, Nanoscale patterning
Processing Technique (former Function and Method): 
Researchers and (Mentors): 
Maryanne Tung, Hansen Qiao, (Michelle Rincon), (Archana Kumar), (Jim Kruger)
Nano Nugget(s): 
Drawing of DSA process

In this standard operating procedure (SOP), we propose a recipe for DSA with 70:30 PS-b-PMMA.

Here, we describe our strategy for inspecting the cross-section of features transferred from the BCP into an underlying hard material (e.g. SiO2, Si).
