Ultralow Spin-on Dielectrics (k < 2.0) with Superb Mechanical properties as Interlayer Dielectrics for the Next Generation System LSI

Sogang University Research Foundation, Seoul, Korea


Our ultralow spin-on dielectrics (k=1.94) show excellent mechanical properties (E=7.2GPa) which are closely relative to sizes (r<2nm) and uniform distribution of pores. These remarkable results are obtained by the specially designated reactive porogens. The reactive porogens can prevent pore aggregation due to their reactivity with organosilicates during sol-gel reaction.

Primary Application Area: Electronics, Sensors & Communications

Technology Development Status: Prototype

Technology Readiness Level: TRL 5


Value Proposition: We used chemically reactive porogens and controlled the size and distribution of nanopores. Therefore, we succeed to control the mechanical properties even at high porosities, which can withstand CMP processing. ITRS 2013 indicates this ULK material will be expected to be applicable to 8 nm node in 2027.
