To achieve higher resolution than conventional optical imaging would allow, we will employ an innovative approach called absorbance modulation (AM), in which a layer of photochromic molecules is placed on top of the photoresist.6 The photochromic molecules squeeze the diameter of the light transmitted into the photoresist. One-Color Reversible Control of Photochromic Reactions in a Diarylethene Derivative: Three-photon Cyclization and Two-Photon Cycloreversion by Near IR Femtosecond Laser Pulse at 1.28 μm. An optical-lithography system employs independently focused light beams for manufacturing custom semiconductors. Photochromism is simply defined as the light induced reversible change of colour. (Photoactive cyclophanes 5) The 1H NMR (Figure 10 and Supporting Information p S2) and the 13C NMR spectra ( 52 distinct signals are observed, see Experimental) point to the absence of symmetry in the molecule.

Photochromic molecules can be loosely divided into two types: those that returnto their initial state at a rate dependent on the ambient temperature ("thermally reversible" photochromic materials), and those which are thermally stable, .
