New polymers are provided that have non-carbon tetravalent species (Si, Ti, Ge, Zr, Sn) and photoimageable compositions that contain such polymers. Preferred polymers are organic, e.g. one or more polymer repeat units comprise carbon atom(s). Particularly preferred are polymers that comprise SiO 2 or TiO 2 repeat units and which can be highly useful as a resin component of resists imaged at short wavelengths such as sub-300 nm and sub-200 nm. |
