摘要:
The present invention discloses a method of providing a substrate, the substrate having a first metal line and a second metal line isolated horizontally by a dielectric; forming an etch stop layer over the substrate; reducing thickness of the etch stop layer over the first metal line, leaving thickness unchanged over the second metal line; forming an interlayer dielectric (ILD) over the etch stop layer; and removing the ILD over the second metal line. The present invention further discloses a structure that includes a substrate; a first metal line and a second metal line located over the substrate; a dielectric located over the substrate adjacent to the first metal line and the second metal line; an etch stop layer located over the first metal line, the second metal line, and the dielectric, the etch stop layer being thicker over the second metal line; and a via located over the thicker etch stop layer over the second metal line.

Disclosed is a system for priming a fluid jetting device. The system includes a fluid trench configured within a fluid jetting chip of the fluid jetting device and at least one first channel fluidly coupled to the fluid trench. The at least one first channel extends vertically between the fluid jetting chip and a mounting unit adapted to support the fluid jetting chip, and is adapted to supply a priming fluid to the fluid trench. The system further includes at least one second channel fluidly coupled to the fluid trench. The at least one second channel extends vertically between the fluid jetting chip and the mounting unit, and is adapted to drain-out the priming fluid from the fluid trench. Further disclosed are systems for priming a fluid jetting device, in accordance with various embodiments of the present disclosure.

A simplified system and method for remotely monitoring and optionally further controlling pumpjack operating parameters of a pumpjack located at a distant site but within wireless cell phone station reception. Sensors situated on a pumpjack monitor and create analog output of operational conditions of the pumpjack. Digitizing means digitize the analog output of the sensors to digital data, and modem means transmit the digital data via a wireless cellular network to a network server. A user's computer communicates with the network server via the internet, and accesses the digital data to obtain information regarding the operational conditions of the pumpjack.

A method associated with the selection of tubulars for hydrocarbon production is described. In particular, the method is associated with the evaluation of performance limits of threaded connections. In this method, constituents of an evaluation group of threaded connections are determined via model analysis. Then, physical testing on a first group of threaded connections in the evaluation group is conducted. Modeling analysis on the first group and a second group of threaded connections is performed, wherein the second group are not physically tested. Once modeled, the results from the physical testing and the modeling analysis are compared to assess a characteristic performance factor for the first group. Then, the characteristic performance factor is applied to the second group, and the performance limits are defined based on this characteristic performance factor.

A system for tracking client contacts for a host organization utilizes a multimedia database and a user interface at a connected computer device. The database stores client communications as full content, and relates contacts by issue, and the user interface displays client contact communications as objects, such as icons, in issue related chronological strings. In a preferred embodiment the interface also provides an input facility for a host agent to select appropriate responses to client communications, to make commitments for response, to assign responsibility for commitments, and to notify personnel affected by entered commitments in various ways, such as reminders. Other notifications include fulfilled and unfulfilled commitments.

Micro-fluid ejection heads and methods for extending the life of micro-fluid ejection heads. One such micro-fluid ejection head includes a substrate having a plurality of thermal ejection actuators. Each of the thermal ejection actuators has a resistive layer and a protective layer thereon. A flow feature member is adjacent the substrate and defines a fluid feed channel, a fluid chamber associated with at least one of the actuators and in flow communication with the fluid feed channel, and a nozzle. The nozzle is offset to a side of the chamber opposite the feed channel. A polymeric layer having a degradation temperature of less than about 400° C. overlaps a portion of the at least one actuator associated with the fluid chamber and positioned less than about five microns from at least an edge of the at least one actuator opposite the fluid feed channel.

摘要:
A system and method are disclosed for high temperature protection of combustor and other components by controlling the temperature of combustion chamber gases in a fuel cell system tail gas burner using a nozzle or plurality of nozzles to inject water or water vapor upstream, downstream or directly into the combustion chamber. A variable speed pump, actuated valve or other flow metering device regulates the supply of water or water vapor to the nozzles. For the case of water vapor, an evaporator is required between the pump and nozzles. Flow regulation is effected by a control algorithm that reacts to combustor temperature, changes in the power production of the fuel cell system and/or other related system parameters.
