Abstract Glass as an alternative printed circuit board material and interposer has been investigated for use in the micro-electronics industry. Electroless copper plating is used to provide conductive layer, but there limited understanding of how surface topography glass substrate affects copper/glass bonding strength exhibited current literature. A laser ablation technique was prepare surfaces...

Effective and cost favorable procedures for hermetical encapsulation of MEMS-structures on wafer level can be fabricated by wafer bonding technologies like the seal glass bonding and by suitable connection technologies routing the electrical potential through the chip structure. Within the paper the parameters of the print and bonding process will be presented and the print process limits will ...

This paper reports the use of time resolved pulse discharge spectroscopy for detecting organic vapors in ambient air. The impact of both sample duration and delay is investigated. A pulsed micro-discharge, consuming only 400 µJ of energy, is struck by applying a high voltage pulse between two closely spaced electrodes patterned on a glass substrate. As a result, the ambient gas in the glow regi...

Achieving high fidelity chemical synthesis on glass plates has become increasingly important, since glass plates are substrates widely used for miniaturized chemical and biochemical reactions and analyses. DNA chips can be directly prepared by synthesizing oligonucleotides on glass plates, but the characterization of these micro-syntheses has been limited by the sub-picomolar amount of material...

Isomerisation kinetics of the 9c11t and 10t12c Conjugated Linoleic Acids (CLA) in triaclglycerols at isothermal conditions (250, 280 and 325 o C) has been studied by infrared spectroscopy. Fifteen micro liter portions of the glycerides were placed in micro glass ampoules and sealed under nitrogen. Several glass tubes containing the same triacylglycerols were then subjected to thermal treatment....

Glass transition, in which viscosity of liquids increases dramatically upon decrease of temperature without any major change in structural properties, remains one of the most challenging problems in condensed matter physics despite tremendous research efforts in past decades. On the other hand, disordered freezing of spins in magnetic materials with decreasing temperature, the so-called "spin g...

The electric impedance of cultured myoblasts oriented on the scaffold with micro pattern has been measured between surface electrodes in vitro. Several parallel lines of micro rectangular ridges (0.001 mm height, 0.003 mm width, and 0.003 mm interval) have been made between a pair of the surface titanium electrodes at the surface of the scaffold of glass by the photolithography technique. C2C12...

Metal alloys have material properties that are very appealing for micro electro mechanical systems (MEMS), but present a challenge for process integration within a lithographic manufacturing sequence of the type used in the semiconductor industry. The batch-mode micro electrodischarge machining (μEDM) discussed here uses lithographically-fabricated electrode arrays with high density and high un...
