Abstract

SOG etchback was studied using Applied Materials' 200mm MxP+ etch chamber on Allied Signal's SOG (spin-on-glass) T11 and low κ SOP (spin-on-polymer) 418 together with liner films of PE-oxide and oxynitride for IMD (inter-metal dielectric) planarization. Excellent chamber performance and wide process window were demonstrated. Etch selectivities between various SOG and liner films are tunable in a wide range allowing optimization of IMD planarization.
