generating switchable and reconfigurable optical vortices via photopatterning of liquid crystals
Advanced Materials, 2014Co-Authors: Bingyan Wei, Yang Ming, S Rubin, Jianguo Wang, Vladimir G ChigrinovAbstract:Liquid-crystal fork gratings are demonstrated through photopatterning realized on a DMD-based Microlithography system. This supplies a new strategy for generating fast switchable, reconfigurable, wavelength-tolerant and polarization-insensitive optical vortices. The technique has great potential in broad fields such as OAM-based quantum computations, optical communications, and micromanipulation.

Photoresists for Microlithography
Resonance, 2002Co-Authors: Debmalya Roy, P. K. Basu, Sridhar V K EswaranAbstract:Characteristics of photoresists used in Microlithography are highlighted. The microstructure of the matrix polymer used in these photoresists is critical for ensuring good lithographic performance and the same can be evaluated by using modern NMR spectroscopic techniques. It is now well-known that highly ordered ‘alternate’ and ‘semi-alternate’ tailor-made novolaks lead to better performing photoresists.

Photoresists for Microlithography
Resonance, 2002Co-Authors: P. K. Basu, Sridhar V K EswaranAbstract:Photoresist technology, which is used for micro-patterning exploits changes in properties of polymeric materials, such as their solubility or volatility, upon photo-irradiation. This process has greatly benefitted from the knowledge base of organic chemistry and photo-induced organic transformations. The role of chemistry in the development of photoresists is described in this article.

Hydrogenated poly(p-vinylphenol) for Microlithography
Industrial & Engineering Chemistry Research, 1996Co-Authors: Tadashi Matsumoto, Mitsuru Akaho, Takeshi Noguchi, Kunishige Otsu, Teruki Matsukami, Masao KanekoAbstract:The characterization of partially hydrogenated poly(p-vinylphenol)s was carried out. By hydrogenation, oxidized sites of the polymers such as quinoid were reduced and the phenolic moiety was converted to cyclohexanolic structure. Accompanied with the structural changes, light transmittance was improved in a wide range of wavelength from visible to the deep-UV region. As the degree of hydrogenation increased, the alkali dissolution rate decreased, while the polymers showed very constant glass transition temperatures and etch durabilities to CF4/O2 plasma. These properties of hydrogenated poly(p-vinylphenol)s are considered to be suitable for a variety of photosensitive applications, especially photoresist materials for Microlithography under deep-UV exposure.
