Ultra-thin polymeric dielectrics are of great interest for the ever-increasing development high-performance novel electronics. Up to date, fabrication polymer layers as thin few nanometers is still an extremely demanding process. Here, we report a facile method fabricate molecularly (4 nm–5 nm) plasma-hardened photoresist (PHPR) by applying O2 plasma treat surface (SPR 220) cross-link constitue...

Polymers are used in biological micro-nanoelectromechanical systems BioMEMS/NEMS applications due to their desirable mechanical properties, biocompatibility, and reduced cost relative to silicon microfabrication processes. Understanding the interfacial properties of the films that are used in BioMEMS/NEMS serves as a useful tool in obtaining higher device yield and greater mechanical reliabilit...

We present a coarse-grained model for molecular dynamics simulations of an epoxy system composed of epoxy phenol novolac as epoxy monomer and bisphenol-A as the cross-linking agent. The epoxy and hardener molecules are represented as short chains of connected beads, and cross-linking is accomplished by introducing bonds between reactive beads. The interbead potential, composed of Lennard-Jones,...

Plastics and glues are common causes of occupational dermatoses, but only few reports have dealt with patch-test reactions caused by plastic and glue allergens. Patients exposed to plastics and remitted to an occupational dermatology clinic, were patch-tested with 50-53 plastic and glue allergens during a 6-year period. Conventional patch-test techniques were used. The most common causes of all...

A pulsed beam of hyperthermal fluorine atoms with an average translational energy of 4.8 eV has been used to demonstrate anisotropic etching of Si. For 1.4 Hz operation, a room-temperature etch rate of 300 Å/min for Si~100! has been measured at a distance of 30 cm from the source. A 14% undercutting for room-temperature etching of Novolac-masked Si features was achieved under single-collision c...

Since the last decade, there is a growing need for patterned biomolecules for various applications ranging from diagnostic devices to enabling fundamental biological studies with high throughput. Protein arrays facilitate the study of protein–protein, protein–drug or protein–DNA interactions as well as highly multiplexed immunosensors based on antibody–antigen recognition. Protein microarrays a...
