Systems and methods for insitu post atomic layer deposition (ALD) destruction of active species are provided. ALD processes deposit multiple atomic layers on a substrate. Pre-cursor gases typically enter a reactor and react with the substrate resulting in a monolayer of atoms. After the remaining gas is purged from the reactor, a second pre-cursor gas enters the reactor and the process is repeated. The active species of some pre-cursor gases do not readily purge from the reactor, thus increasing purge time and decreasing throughput. A high-temperature surface placed in the reactor downstream from the substrate substantially destroys the active species insitu. Substantially destroying the active species allows the reactor to be readily purged, increasing throughput.

This paper presents the fabrication and preliminary testing of a novel piezoelectric microvalve. Fabrication has three steps, which are the actuator fabrication, valve body fabrication and assembly of the microvalve. Fabricating an actuator involves cutting piezoelectric and brass beams, gluing the brass and piezoceramic beams into a trimorph sandwich structure, and curing them under pressure at elevated temperatures. Actuators are then wired either by using conductive epoxy or soldering. Valve body parts are constructed from single crystal silicon substrates using deep reactive ion etching (DRIE). DRIE is a subtractive process, whereby a mask is created on the surface of the stock, which will shield the parts that are not to be machined. Refinements in the actuator manufacturing process are made to increase the quality and decrease the fabrication time. Using a photonic probe, tip deflections of the actuators have been tested at various temperature and voltage levels. Currently, the valves are being assembled. Once assembled, multiple microvalves will undergo cold flow testing with air followed by extensive flow extensive flow testing at elevated temperatures with humidified hydrogen.

In certain example embodiments, a transparent conductive oxide (TCO) based front electrode for use in a photovoltaic device may be made by sputtering a ceramic target in a gaseous atmosphere tailored to optimize the electro-optical properties of the resulting TCO coating. For example, using a particular type of atmosphere in the sputtering process can permit the resulting TCO coating (e.g., of or including zinc oxide, zinc aluminum oxide, and / or ITO) to more readily withstand subsequent high temperature processing which may be used during manufacture of the photovoltaic device. Moreover, processing energy resulting from the high temperature(s) may also optionally be used to improve crystallinity characteristics of the TCO.
