An object is to provide a semiconductor device of which a manufacturing process is not complicated and by which cost can be suppressed, by forming a thin film transistor using an oxide semiconductor film typified by zinc oxide, and a manufacturing method thereof. For the semiconductor device, a gate electrode is formed over a substrate; a gate insulating film is formed covering the gate electrode; an oxide semiconductor film is formed over the gate insulating film; and a first conductive film and a second conductive film are formed over the oxide semiconductor film. The oxide semiconductor film has at least a crystallized region in a channel region.

We present a simple and usable noise model for the raw-data of digital imaging sensors This signal-dependent noise model, which gives the pointwise standard-deviation of the noise as a function of the expectation of the pixel raw-data output, is composed of a Poissonian part, modeling the photon sensing, and Gaussian part, for the remaining stationary disturbances in the output data We further explicitly take into account the clipping of the data (over- and under-exposure), faithfully reproducing the nonlinear response of the sensor We propose an algorithm for the fully automatic estimation of the model parameters given a single noisy image Experiments with synthetic images and with real raw-data from various sensors prove the practical applicability of the method and the accuracy of the proposed model

Despite their increasing sophistication, wireless sensor networks still do not exploit the most powerful of the human senses: vision. Indeed, vision provides humans with unmatched capabilities to distinguish objects and identify their importance. Our work seeks to provide sensor networks with similar capabilities by exploiting emerging, cheap, low-power and small form factor CMOS imaging technology. In fact, we can go beyond the stereo capabilities of human vision, and exploit the large scale of sensor networks to provide multiple, widely different perspectives of the physical phenomena. To this end, we have developed a small camera device called Cyclops that bridges the gap between the computationally constrained wireless sensor nodes such as Motes, and CMOS imagers which, while low power and inexpensive, are nevertheless designed to mate with resource-rich hosts. Cyclops enables development of new class of vision applications that span across wireless sensor network. We describe our hardware and software architecture, its temporal and power characteristics and present some representative applications.

Cyclops: in situ image sensing and interpretation in wireless sensor networks

Memory devices are shown that include a body region and a connecting region that is formed from a semiconductor with a lower band gap than the body region. Connecting region configurations can provide increased gate induced drain leakage during an erase operation. Configurations shown can provide a reliable bias to a body region for memory operations such as erasing, and containment of charge in the body region during a boost operation.

A pinned photodiode with a pinned surface layer formed by a self-aligned angled implant is disclosed. The angle of the implant may be tailored to provide an adequate offset between the pinned surface layer and an electrically active area of a transfer gate of the pixel sensor cell. The pinned surface layer is formed by employing the same mask level as the one employed for the formation of the photodiode region, and then implanting dopants at angles other than zero degrees.

Semiconductor structures including a movable switching element having a base disposed on a conductive pad, a body extending from the base, and an end laterally adjacent and spaced apart from a conductive contact are disclosed. Upon application of a threshold voltage, the movable switching element may deform toward the conductive contact via an electrical field, establishing electrical contact between the conductive pad and the conductive contact. Various methods may be used to form such semiconductor structures, and switching devices including such semiconductor structures. Memory devices and electronic systems include such switching devices.
