Abstract:
1. A composition of matter, comprising: a fluid for forming a photoresist layer on a surface of a substrate, the fluid comprising; photosensitive molecules, each of the photosensitive molecules having an axis, wherein each photosensitive molecules aligns with its axis having a particular direction with respect to the normal to the surface of the substrate when the fluid is formed as a layer on the surface of the substrate, and wherein each photosensitive molecule has a different sensitivity to light of wavelength λ having a first linear polarization parallel to the axis than to light of a second linear polarization orthogonal to the first polarization such that a fluence of light of either one of the first or second polarizations causes a reaction in the photosensitive molecules which allows development of the layer as a photoresist layer, and that same fluence of light of the orthogonal polarization does not cause a reaction which allows development of the layer as a photoresist layer.
