High stress nitride film and method for formation thereof
ActiveUS20060199357A1Increase the tensile stressSemiconductor/solid-state device manufacturingChemical vapor deposition coatingDopantNitrogen
A silicon nitride film is formed on a substrate in a reaction chamber by introducing trisilane and a reactive nitrogen species into the chamber in separate pulses. A carbon precursor gas is also flowed into the chamber during introduction of the trisilane and / or during introduction of the reactive nitrogen species, or in pulses separate from the trisilane and reactive nitrogen species pulses. The carbon is used as a dopant in the silicon nitride film and advantageously allows a high stress silicon nitride film to be formed.

Methods and apparatus for work management and routing
Methods and apparatus for service-level based and / or skills-based assignment of a work item to one (or more) of a plurality of resources based on fitness, for example, of skills required by the former to those provided by the latter. Assignment takes into account the level of stress on the work item and / or resources, such that the number of resources fit for assignment varies as the level of stress varies. Systems according to the invention can be used, by way of example, to route a call or other request made by a customer to a service center. The requirements for processing the call (determined, for example, by an incoming call operator) are matched against the skill sets of available customer service agents, taking call and / or resource stress levels into account. For example, some implementations may match an incoming call having a low stress factor (e.g., a newly received call from a standard customer) to a smaller pool of agents with both required and desired skills, while assigning a call with a higher stress factor to a larger pool of agents with at least required skills. Other embodiments may match an incoming call having a low stress factor to the larger pool of agents having at least the required skills, while assigning a call with a higher stress factor (e.g., a call from a priority customer) to an agent from the smaller pool of agents who have both required and desired skills.

Embolic filter frame having looped support strut elements
An improved embolic filter frame having looped support struts. The frame configuration provides enhanced longitudinal compliance, improved sealing against a vessel wall, low profile delivery, and a short deployed length. The looped support struts have a high degree of “radial” stiffness with a low degree of “longitudinal” stiffness. In the deployed state, the frame exerts a relatively high stress onto a vessel wall to maintain an effective seal, yet remains compliant in the longitudinal direction. Minor displacements of the support wire or catheter are therefore not translated to the filter. The looped support struts elongate when tensioned and assume a compressed and essentially linear form. While constrained in this linear state by a delivery catheter, the support struts exert minimal stress onto the delivery system. The overall delivery profile and stiffness are therefore reduced. When the delivery catheter constraint is removed during deployment, the struts “snap open” and assume a looped configuration which exert a high degree of force onto the vessel wall, creating an enhanced filter to vessel wall seal. In addition, the looped struts and the central collar connecting the support struts to the support wire, are positioned essentially within the plane of the filter opening. The overall deployed length of the embolic filter is therefore reduced.

A damper body for a magnetorheological (MR) damper and associated methods of forming the damper body. The damper body is formed of a base material, such as a steel, and is coated with an abrasion-resistant layer comprising chromium. The layer of chromium provides a sliding wear surface for sliding contact with a reciprocating piston. To avoid high-stress abrasive wear over the expected service life of the magnetorheological damper, the layer of chromium has a minimum thickness greater than or equal to a minimum thickness of about 8 .mu.m. In other embodiments, be fore applying the abrasion-resistant layer of chromium, the damper body is coated with a layer of a hard coating material having a hardness greater than the hardness of the base material. The effective hardness of the damper body is a composite of the respective hardnesses of the base material comprising the damper body and the layer of hard coating material.

Stress level of a nitride film is adjusted as a function of two or more of the following: identity of a starting material precursor used to make the nitride film; identity of a nitrogen-containing precursor with which is treated the starting material precursor; ratio of the starting material precursor to the nitrogen-containing precursor; a set of CVD conditions under which the film is grown; and / or a thickness to which the film is grown. A rapid thermal chemical vapor deposition (RTCVD) film produced by reacting a compound containing silicon, nitrogen and carbon (such as bis-tertiary butyl amino silane (BTBAS)) with NH3 can provide advantageous properties, such as high stress and excellent performance in an etch-stop application. An ammonia-treated BTBAS film is particularly excellent in providing a high-stress property, and further having maintainability of that high-stress property over repeated annealing.

Method to improve charge pump reliability, efficiency and size
A dynamic clamp is used in conjunction with capacitors with thinner dielectric or with deep trench capacitors to solve the problem of dielectric breakdown in high stress capacitors. The dynamic clamp is realized using a two stage pump operation cycle such that, during a first stage pump cycle, a middle node of a pair of series connected capacitors is pre-charged to a supply voltage and, during a second stage pump cycle, the middle node is coupled by a boost clock. Thus, at any moment in the pump operation cycle, the voltage across the capacitors is held within a safety range.
