Stress-tuned, single-layer silicon nitride film
InactiveUS20050170104A1Careful control over amountHigh voltageElectric discharge tubesSemiconductor/solid-state device manufacturingDeposition temperatureChamber pressure
We have discovered that is possible to tune the stress of a single-layer silicon nitride film by manipulating certain film deposition parameters. These parameters include: use of multiple (typically dual) power input sources operating within different frequency ranges; the deposition temperature; the process chamber pressure; and the composition of the deposition source gas. In particular, we have found that it is possible to produce a single-layer, thin (300 Å to 1000 Å thickness) silicon nitride film having a stress tuned to be within the range of about −1.4 GPa (compressive) to about +1.5 GPa (tensile) by depositing the film by PECVD, in a single deposition step, at a substrate temperature within the range of about 375° C. to about 525 ° C., and over a process chamber pressure ranging from about 2 Torr to about 15 Torr.

Methods and apparatus for thermally coupling a heat sink to a circuit board component
InactiveUS7019976B1Minimize amount of stressLimit amount of stressSemiconductor/solid-state device detailsSolid-state devicesHeat spreaderLOCAL TOLERANCE
A heat sink has a flexure member attached to a base of the heat sink and located between the base and an associated circuit board component. As the heat sink attaches to a circuit board carrying the circuit board component, the flexure member conforms to the surface of the circuit board component, thereby thermally contacting the circuit board component. The flexure member absorbs local tolerance differences on the circuit board component to provide a relatively uniform stress across the surface of the circuit board component. The flexure member further limits the amount of stress generated by the heat sink on the circuit board component. When used in conjunction with a heat sink spanning several circuit board components, the flexure member absorbs global tolerance differences among the circuit board components, thereby providing relatively uniform stresses to all of the circuit board components and limiting the amount of stress experienced by any one circuit board component.
