摘要:
This invention discloses a backside illuminated image sensor without the need to involve a mechanical grinding process or a chemical-mechanical planarization process in fabrication, and a fabricating method thereof. In one embodiment, an image sensor comprises a semiconductor substrate, a plurality of light sensing elements in the semiconductor substrate, and a cavity formed in the semiconductor substrate. The light sensing elements are arranged in a substantially planar manner. The cavity has a base surface overlying the light sensing elements. The presence of the cavity allows the image to reach the light sensing elements through the cavity base surface. The cavity can be fabricated by etching the semiconductor substrate. Agitation may also be used when carrying out the etching.
摘要:
Snapshot data may be received indicative of a current state of resources that deliver healthcare to a plurality of patients associated with a healthcare enterprise. The received snapshot data may be automatically used to initialize a healthcare enterprise simulation model. The healthcare enterprise simulation model may then be executed to automatically generate a predicted future state of the resources at a predetermined point in time. Some embodiments may automatically suggest mitigation strategies based on simulated scenarios reflecting potential bottlenecks and appropriate actions that may be taken by the enterprise. The system may continuously and automatically monitor forecast accuracy to detect potential anomalies.

摘要:
An electronic or micromechanical device having first (11) and second (12) surfaces and a via extending through the device from the first surface to the second surface. The via comprises integrally formed first (84, 86), second (82) and third (88) portions. The first portion (84, 86) extends from the first surface (11) to the second surface (12). The second portion (82) extends over a part of the first surface (11) of the device. The third portion (88) extends over a part of the second surface (12) of the device. Preferably the first portion comprises first and second parts, the second part extending through an active region of the device and having a narrower width than the first part. A method of forming and filling the via is also disclosed.
