A Uniform Lying Helix (ULH) liquid crystal device (LCD) fabricated by utilizing the characteristics of shear flow alignment as well as dielectric anisotropy was demonstrated. Cholesteric liquid crystals with a short helical pitch can exhibit an electric field-induced tilt. These experimental results indicate that it is possible to realize a high-speed response flexible LCD using plastic substra...

Each film coating formulation and film forming polymer has an individual limiting maximum viscosity value for processability which depends on the type of nozzle and coater used, as well as on the batch size. In order to optimize efficiency and quality, knowledge of the formulation dependant viscosity curves is absolutely necessary. Fig. 1: Thermo Scientific HAAKE RotoVisco 1 rotational rheomete...

This paper discusses a novel approach of using a developer-soluble gap fill material, wherein the gap fill material is coated in a layer thick enough to planarize all the topography and is then recessed using a standard 0.26N TMAH developer. The material recess process takes place in the same coater track where it is coated and therefore simplifies the process and increases wafer throughput. Pe...

Solvent annealing [1-3] has recently emerged as a powerful alternative to thermal annealing of block copolymer (BCP) thin films and nanocomposites. Taking a more general point of view, solvent treatment procedures, employing the selectivity of the solvents towards the different blocks, can produce new structures [4], and provide fascinating insights into the swelling kinetics and instabilities ...
