Abstract: A method for fabricating a suspended structure including a layer of membrane material over a substrate. The suspended structure overlies a cavity in the substrate. The method starts by generating a sacrificial layer comprising a first material that can withstand temperatures typically encountered in subsequent conventional semiconductor processing steps. In the preferred embodiment of the present invention, the bond between sacrificial layer and the underlying substrate must be capable of withstanding temperatures greater than the Si—Al eutectic point. A layer of membrane material is then deposited over the sacrificial layer. The membrane material comprises a second material different from the first material. An opening is introduced in the layer of membrane material thereby exposing the sacrificial layer. A first etchant is applied to the sacrificial layer through the opening until the sacrificial layer is removed leaving a portion of the cavity. The first etchant is chosen such that the first etchant removes the first material more rapidly than the second material. Finally, a second etchant is introduced into the cavity to expand the cavity. The second etchant is chosen such that the second etchant removes the substrate more rapidly than the second material. The first material is preferably PSG, thermal silicon dioxide, low temperature oxide, or tungsten.

Abstract: A thermally-activated gas extraction device that comprises a bubble capture chamber, an exhaust manifold, a tapered extraction chamber and an extraction heater associated with the tapered extraction chamber. The tapered extraction chamber extends from the bubble capture chamber towards the exhaust manifold and has a cross-sectional area that increases towards the exhaust manifold. A gas removal method in which the gas extraction device is provided, a bubble of gas is accumulated in the bubble capture chamber, a portion of the liquid in the tapered extraction chamber heated to nucleate a bubble of vapor, and the bubble of vapor is heated to explosively expand the bubble of vapor into contact with the walls of the tapered extraction chamber and into contact with the bubble of gas to form a composite bubble. Contact with the walls of the tapered extraction moves the composite bubble towards the exhaust manifold. Finally, heating of the composite bubble is discontinued to condense the vapor in the composite bubble.

Abstract: A switching element defines a transmitting state and a reflecting state for a pair of intersecting waveguides that have a gap at their intersection. In the preferred embodiment, the switching element exhibits total internal reflection at the gap sidewall from one waveguide to the other when not in the transmitting state. In the transmitting state, index-matching liquid fills the gap, enabling light to continue in the original waveguide direction. The switching element may use ink jet techniques or bubble techniques to displace index-matching liquid. The index-matching fluid may be projected from a gap between the waveguides by a jet mechanism, or a vapor or dissolved gas bubble may be formed to fill the gap between the waveguides to provide the reflecting state for the switching element. Using either of the techniques, heaters are employed to initiate the switching operation. In some embodiments, more than one heater is utilized. In the preferred embodiment, waveguides are formed on one substrate and heaters are formed on another. Then the substrates are aligned and bonded together to position the heaters in very close proximity to the intersection between the waveguides. Preferably, the switching element is one element in a matrix of such elements for routing signals between arrays of input and output waveguides.

Abstract: A process is disclosed for removing residual sulfur from a hydrotreated naphtha feedstock. The feedstock is contacted with molecular hydrogen under reforming conditions in the presence of a less sulfur sensitive reforming catalyst to convert trace sulfur compounds to H.sub.2 S, and to form a first effluent. The first effluent is contacted with a solid sulfur sorbent to remove the H.sub.2 S and form a second effluent. The second effluent is then contacted with a highly selective reforming catalyst under severe reforming conditions. Also disclosed is a method using a potassium containing sulfur sorbent made from nitrogen-free potassium compounds.
