General description

1,2-Bis(trichlorosilyl)ethane is an alkylchlorosilane that couples with surface atoms present on the metal surfaces. It is mainly utilized as a protective coating and a coupling agent that enhances the absorption of the self-assembled monolayer (SAM) on the surface of the metal. It chemically modifies the substrate material and acts as an anti-corrosive layer.

New cross-linking reagents were synthesized and mixed with polystyrene (PS) in solution to form a blend. Thin-films were spin-coated from the blend and then cross-linked by thermal activation at relatively low temperature (100 °C) to form cross-linked gate dielectrics. This new
