Hot embossing for micropatterned cell substrates
Biomaterials, 2004This paper reports the development of a technique for preparing microtextured polymer substrates for cell growth and studies the response of osteoblast cells grown on these surfaces. The surfaces were manufactured with hot embossing, where a silicon micromachined printing master was pressed into a thermoplastic polymer substrate at elevated temperature,

Fabrication of plastic microchips by hot embossing
Lab on a Chip, 2002Plastic microchips with microchannels (100 microm wide, 40 microm deep) of varying designs have been fabricated in polymethylmethacrylate by a hot embossing process using an electroform tool produced starting with silicon chip masters. Hot-embossed chips were capped with a polymethylmethacrylate top using a proprietary solvent bonding process.

Micro Hot Embossing for Replication of Microstructures
Japanese Journal of Applied Physics, 2003Micro hot embossing is a novel technique for low-cost and mass-production of MEMS components in plastics, and will potentially find wide applications in optical communications and micro fluidics areas. The goal of this research is to develop a micro hot embossing process for high quality pattern transfer from masters to polymer materials.

Hot embossing of discrete microparts
Polymer Engineering & Science, 2009AbstractThe hot embossing process has so far been developed mainly for replication of surface structures on thermoplastic substrates. Because of the lack of a through‐thickness action, fabrication of discrete microparts such as microgears is considered difficult.

Deformation Behavior of Glass Nanostructures in Hot Embossing
ACS Applied Materials & Interfaces, 2020In the nanoscale glass formation, the flow and deformation behavior of glass materials are quite different from those in the macroscale because the mold cavity influences the viscous flow behaviors of glass because of the size effect. The knowledge of macroglass molding process no longer applies to the fabrication of glass microparts by hot embossing ...

Hot embossing on polymethyl methacrylate
2006 8th Electronics Packaging Technology Conference, 2006Micro hot embossing experiments were conducted on polymethyl methacrylate (PMMA) to look at the effects of holding load, temperature and time on the fidelity of line arrays representing micro channels. The results revealed that the holding temperature was a more sensitive parameter than the others due to its large effect on the polymer's viscoelastic ...

Ultrasonic Vibration Hot Embossing
International Polymer Processing, 2005Abstract Hot embossing has become a popular method for replicating precise micro-features onto large plastic plates. However, a long cycle time of the process due to conventional electric heating or hot oil heating is one of problems that confound the overall success of this technology. This study proposed a novel hot embossing method by

APPLICATION OF MICRO HOT EMBOSSING FOR MEMS STRUCTURES
International Journal of Computational Engineering Science, 2003MEMS (Micro Electro Mechanical Systems) products are being spread from laboratory to industries. But Silicon-based MEMS products are usually expensive and not suitable for low cost production. Hence, there is an emerging need in terms of cost effectiveness to transfer MEMS from silicon-based materials to other materials, such as glasses and polymers ...
