摘要： Bubble stability within an optical switch is enhanced by controlling the expansion or movement of a bubble from a liquid-containing trench into available adjacent spacing. Typically, the adjacent spacing is formed between an optical waveguide substrate and a heater substrate, where the heater substrate includes a microheater for forming the bubble. The bubble enhancement is provided by intentionally altering surface features along at least one of the substrates.

摘要： In the field of imaging, various components may contribute to a loss in resolution at higher spatial frequencies, both horizontally and vertically. Higher spatial frequencies may occur at the edge of an image, where there may be a large transition in the signal output between adjacent pixels. To compensate, an edge enhancement method that produces overshoots in the transitions of the video image signal is used. One of the problems with the edge enhancement method is that the noise in the input signal may not be adequately suppressed. To suppress the background noise in the video image signal while still performing the desired edge enhancement function, biasing circuitry may be used to suppress the smaller transitions in the input signal. In particular, the biasing circuitry may be placed in the signal path between the output of a first delay line and the noninverting inputs of two of the signal amplifiers. In this manner, the smaller transitions in the signal which represent background noise may be suppressed, while the edges of the video image signal are still enhanced.

摘要： A method of making high voltage complementary bipolar and BiCMOS devices on a common substrate. The bipolar devices are vertical NPN and PNP transistors having the same structure. The fabrication process utilizes trench isolation and thus is scalable. The process uses two epitaxial silicon layers to form the high voltage NPN collector, with the PNP collector formed from a p-well diffused into the two epitaxial layers. The collector contact resistance is minimized by the use of sinker up/down structures formed at the interface of the two epitaxial layers. The process minimizes the thermal budget and therefore the up diffusion of the NPN and PNP buried layers. This maximizes the breakdown voltage at the collector-emitter junction for a given epitaxial thickness. The epitaxial layers may be doped as required depending upon the specifications for the high voltage NPN device. The process is compatible with the fabrication of low voltage devices, which can be formed by placing the sinker regions under the emitter region. The thicknesses of the two epitaxial layers may be adjusted as required depending upon the specifications for the low voltage devices.
摘要翻译：在公共衬底上制造高电压互补双极和BiCMOS器件的方法。双极器件是具有相同结构的垂直NPN和PNP晶体管。制造工艺利用沟槽隔离，因此是可扩展的。该工艺使用两个外延硅层来形成高压NPN集电极，PNP集电极由扩散到两个外延层中的p阱形成。通过使用在两个外延层的界面处形成的沉降片上/下结构来最小化集电极接触电阻。该过程使热预算最小化，因此最小化NPN和PNP埋层的向上扩散。对于给定的外延厚度，这使集电极 - 发射极结处的击穿电压最大化。外延层可以根据需要掺杂，这取决于高压NPN器件的规格。该工艺与低电压器件的制造兼容，这可以通过将沉降片区域放置在发射极区域下而形成。根据低电压器件的规格，可以根据需要调整两个外延层的厚度。

摘要： A method of fabricating a switching element or a matrix of switching elements includes providing a waveguide substrate having at least two waveguides that intersect at a trench such that optical coupling between the waveguides is dependent upon the presence or absence of an index-matching fluid at the intersection of the waveguides with the trench. Fluid is supplied to the trench via a fluid fill-hole that extends through a heater substrate in a direction that is generally perpendicular to a substrate surface on which at least one heater is fabricated. In the preferred embodiment, the fluid fill-hole is formed in a step of inductively coupled plasma (ICP) reactive ion etching (RIE). The waveguide substrate having at least two waveguides and the heater substrate having the heaters and the fill-hole are bonded together after the substrates are aligned such that the trench is in fluid communication with at least one fluid fill-hole and is in thermal communication with at least one heater. Optical fibers are then coupled to the waveguides. Preferably, a structurally weakened edge portion is formed during the ICP RIE step so that the edge portion can be removed after the two substrates are bonded, allowing uninhibited access of the optical fibers to the waveguides.

摘要： An isolation method for separating active regions in a semiconductor substrate by combining field oxide formation with trench isolation is disclosed. Deep trenches are etched in a silicon substrate. An oxide layer is deposited over the entire substrate such that the oxide layer also fills the trenches that have been etched. A layer of polysilicon is deposited over the wafer and etched back to form polysilicon spacers. These polysilicon spacers are used to align a photoresist mask that is used to etch the oxide overlying the active regions of the substrate, thereby resulting in fully planarized isolation regions with fully walled active regions.

摘要： Disclosed is a system to forecast a supply of online advertising demand contracts having day parting targets. The system may receive an online advertising demand contract having a flight duration and a day parting target. The received online advertising demand contract may be processed by converting the day parting target into an hour-of-week day parting target vector. If a first day of the flight duration would generate a conflict in view of the hour-of-week day parting target vector, then the system may generate a new first day contract for the first day of the flight duration.
