The focus of this thesis involves developing general fabrication processes relevant to the manufacture of two new devices for the Microscale technology Energy and Chemical Systems (MECS) program at Oregon State University. The two MECS devices developed, capture dots and transparent thin-film heaters (TTFHs), require unique process development for successful manufacture. Thick photolithography is required for the capture dots and its development is detailed. The capture dots also require copper electroplating. The copper electroplating system and process development are detailed. The TTFHs require a unique heater material, indium tin oxide (ITO). The heater deposition utilizes an ultrasonic lift-off method, also detailed. The complete manufacturing process steps of both the capture dots and the TTFHs are described. Both devices are successfully demonstrated and their electrical properties are discussed.

Magnetic thin films have potential to improve devices such as on-chip inductors, and enable new technologies such as magnetic random access memory (MRAM). The use of magnetic cores in on-chip inductors is typically limited to applications well under 1 GHz. At higher frequencies, the performance of the magnetic core is severely limited by eddy current losses and ferromagnetic resonance. This work investigates the feasibility of using shape anisotropy to increase the ferromagnetic resonance frequency and thus allow the use of thin-film magnetic cores at frequencies up to 3 GHz. Magnetic cores are fabricated on top of existing chip- scale inductors. The effect of core shape and oxide layers, which are added to reduce eddy currents, on the magnetic properties of the film are investigated. Magnetic tunnel junctions (MTJs) are of interest in MRAM and spintronic logic circuit ap- plications due to their non-volatility, low-power operation, and size scalability. One limitation to the creation of scalable magnetic random access memory is thermal stability. For large devices, this energy barrier is proportional to the exchange stiffness of a material. Typically the thermal stability is measured in fabricated MRAM devices, and is used to back-calculate the exchange stiff- ness. This work presents a novel approach which uses images of magnetic domains, in conjunction with vibrating sample magnetometer and ferromagnetic resonance measurements, to measure the exchange stiffness in unpatterned films. This allows for estimation of the thermal stability that can be obtained by a given magnetic free layer without need to fabricate and measure completed de- vices. Using this approach, the exchange stiffness and expected thermal stability in MgO / CoFeB / spacer / CoFeB / MgO free layer structures with various spacer layer materials and thicknesses are compared.

The necessity of on-site, fast, sensitive, and cheap complex laboratory analysis, associated with the advances in the microfabrication technologies and the microfluidics, made it possible for the creation of the innovative device lab-on-a-chip (LOC), by which we would be able to scale a single or multiple laboratory processes down to a chip format. The present book is dedicated to the LOC devices from two points of view: LOC fabrication and LOC application.

IMRET 5 featured more than 80 oral and poster communications, covering the entire interdisciplinary field from design, production, modeling and characterization of microreactor devices to application of microstructured systems for production, energy and transportation, including many analytical and biological applications. A particularly strong topic was the investigation of the potential of microstructuring of reactors and systems components for process intensification. Perspectives of combining local, in situ, data acquisition with appropriate microstructuring of actuators and components within chemical and biological devices were explored in order to enhance process performance and facilitate process control.
