Positive resist consists of a photosensitive coating soln., treated with 0.001-1.0 (wt.) of a siloxane cpds. (I), contg. fluoroalkyl gps., of the formula: RF = X(CF2)m(CH2)p, C6F5, C6F5COCH2CH2 or C6F5CH2; X = F or H; m = 1-10; p = 1 or 2; R' = H or Me; Y = a linear, branched and/or cyclic 2-20 Si methylsiloxanyl gp. or a linear and/or branched 20-100 Si methyl-polysiloxanyl gp.. USE/ADVANTAGE - Addn. of (I) improves the film-forming property, i.e., a surface roughness less than 10nm is attached, making the photoresist esp. suitable for structurising microelectronic devices.
