In a monolithic ceramic electronic component, given that an interval between outer-layer dummy conductors adjacent to each other in an outer layer portion is d1, and that an interval between first and second inner electrodes adjacent to each other in an inner layer portion is d2, 1.7d2≦d1 is satisfied. By reducing a density of the outer-layer dummy conductors in the outer layer portion on that condition, pressing of the inner electrodes through the outer-layer dummy conductors is relieved in a pressing step before firing. As a result, a distance between the inner electrodes can be prevented from being locally shortened. It is hence possible to effectively reduce and prevent degradation of reliability of the monolithic ceramic electronic component, e.g., a reduction of BDV.

The organic thin film transistor may prevent or reduce oxygen and moisture from infiltrating thereinto, and thus may prevent or reduce the degradation of the performance thereof caused by ambient air, prevent or reduce the deterioration thereof, and may more easily be formed into a pattern, thereby exhibiting characteristics suitable for use in electronics.

During the conventional temperature swing adsorption (TSA) process, NF3 co-adsorbed with the impurities is vented during regeneration. This invention is a novel TSA cycle in which the co-adsorbed NF3 is recovered. In this novel TSA cycle, a control scheme is used to stop the adsorption prior to the saturation of the adsorber with impurities and use a recovery purge gas (either co-current or counter-current) to release the co-adsorbed NF3 off the saturated adsorber. The effluent of the inert purge gas can be combined with the effluent of the on-stream vessel or can be recycled to the feed of the on-stream vessel. 10%-100% of the co-adsorbed NF3 is recovered and made available as product in this novel TSA cycle. Thus the overall process yield of NF3 is increased. The removing of the co-adsorbed NF3 from the adsorber also prevents adsorber degradation thus prolonging the useful life of the adsorber.

Two or more outer-layer dummy conductors are successively arranged at predetermined intervals in the height direction, thereby forming a plurality of outer-layer dummy groups. Given that an interval between the adjacent outer-layer dummy conductors within each of the outer-layer dummy groups is d and an interval between the adjacent outer-layer dummy groups is g, g is greater than d. On that condition, the outer-layer dummy groups can be positioned satisfactorily apart away from each other, while plating deposition points are ensured. As a result, pressing of inner electrodes through the outer-layer dummy conductors can be relieved, whereby the distance between the inner electrodes can be prevented from being locally shortened and a reduction of BDV can be prevented.
