Replication of optical components by hot embossing
SPIE Proceedings, 2010Replication technology for microstructures is an essential issue for transforming expensive microstructures to cheap polymer replicas. Hot embossing has proven to be a suitable technology to fulfil the requirements of industrial applications and to fill the gap between the laboratory and the consumer market.

Research on optimization of the hot embossing process
Journal of Micromechanics and Microengineering, 2007The hot embossing of polymer was studied to improve product quality. The finite element method (FEM) was used to analyze the embossing step, the cooling step and the demolding step with respect to product quality. The numerical simulation results show that profile precision is largely influenced by the topological structure of the mold during the ...

Rapid hot embossing of polymer microfeatures
Microsystem Technologies, 2006Although the hot embossing process is gaining popularity in molding polymer micro/nano structures, it needs a breakthrough improvement in reducing cycle time before it can become a mass-production process. In this study, an embossing tool with a rapid heating and cooling capability was investigated to reduce the cycle time.

Hot embossing of microfluidic platform
International Communications in Heat and Mass Transfer, 2006Abstract Microfabrications of polymer are becoming increasingly important and considered as a low-cost alternative to the silicon or glass-based MEMS technologies. However, most of hot embossing studies were done on a thin film that may not fulfill the structure requirement of the product.

Hot embossing of micro-featured devices
IEEE International Conference on Mechatronics, 2005. ICM '05., 2005Polymer microfabrication methods are becoming increasingly important as low-cost alternatives to the silicon or glass-based MEMS technologies. In this study, micro molding via hot embossing was applied to micro-featured used for DNA/RNA test. LIGA like process using UV light aligner was used to prepare silicon based SU-8 photoresist followed by ...

Hot embossing of cyclic olefin copolymers
Journal of Micromechanics and Microengineering, 2009The hot embossing properties of cyclic olefin copolymer (COC) have been examined as a function of comonomer content. Six standard grades of COC with varying norbornene content (61?82 wt%) were used in these experiments in order to provide a range of glass transition temperatures, Tg.
