In this work we report on the magnetron reactive ion etch (MRIE) technology for gallium nitride (GaN) and aluminum gallium nitride (Al x Ga1−x N) using dichlorodifluoromethane (CCl2F2), commonly known as halocarbon 12, with etch rates greater than

Preliminary data from controlled experiments indicate that in plasma electrolysis, metallic electrodes do not have to be immersed in water to produce hydrogen and oxygen as in the case of traditional electrolysis. Instead, the electrodes can interact

Conventional photoresists have been modified by the incorporation of a phosphorus-containing compound, {ital i.e.}, phosphonitrilic chloride trimer (P{sub 3}N{sub 3}Cl{sub 6}). The modification was achieved by simply dissolving P{sub 3}N{sub 3}Cl{sub

A unique process is described wherein solder reflow and joining can be effectively performed without flux in air or in nitrogen. The process involves first converting surface oxides to a new compound which permits reflow and joining to occur. A simpl

Integrated Force Arrays (IFAs) are membrane based actuators that are made of polyimide material. They are metallized membranes that are flexible enough to undergo substantial deformation when a voltage is applied. IFAs can be patterned using the tech

We have previously described a hand crafted prototype intracardiac scanner that consists of a single high frequency PZT piston transducer that is mechanically steered by a micromachine (MEMS) actuator to produce a sector scan. More recently, we have
