Resist characteristics and molecular structure control of polystyrene by plasma polymerization method

The effect of plasma polymerization conditions on the structure of the plasma polymerized styrene were investigated by using Fourier Transform Infrared Ray(FT-IR), Differential Scanning Calorimetry (DSC), Gel Permeation Chromatography(GPC). Plasma polymerized thin film was prepared using an interelectrode inductively coupled gas-flow-type reactor. We show that polymerization parameters of thin film affect sensitivity and etching resistance of plasma polymerized styrene is 1.41~3.93, and deposition rate of that are 32~383[.angs./min] with discharge power. Swelling and etching resistance becomes more improved with increasing discharge power during plasma polymerization. (author). 11 refs., 10 figs., 1 tab.
