Fast luminescent silicon
There are provided mesoporous silica materials containing in their pores stabilized clusters of silicon atom, of size 2 nanometers or less, and capable of photoluminescence to emit fast photons. They are prepared by chemical vapor deposition of silicon or a silicon precursor such as disilane, under soft conditions such as temperature of 100-150 DEG C., into the mesopores of silicate films which have mesoporous channels prepared by growth of the films using a template to control their sizes, but without removing the template residues from the films prior to the chemical vapor deposition. The template residues serve to limit the size of the silicon clusters which conform. The use of the soft conditions on CVD retains the template residues in an intact, substantially unchanged form. The resultant films have clusters of silicon, of 2 nanometer size or less, anchored to the mesopores, and air stable, so that they can be used in optoelectronic devices in conjunction with standard silicon semiconductors.

A signal processing circuit whose power consumption can be suppressed is provided. In a period during which a power supply voltage is not supplied to a storage element, data stored in a first storage circuit corresponding to a nonvolatile memory can be held by a first capacitor provided in a second storage circuit. With the use of a transistor in which a channel is formed in an oxide semiconductor layer, a signal held in the first capacitor is held for a long time. The storage element can accordingly hold the stored content (data) also in a period during which the supply of the power supply voltage is stopped. A signal held by the first capacitor can be converted into the one corresponding to the state (the on state or off state) of the second transistor and read from the second storage circuit. Consequently, an original signal can be accurately read.

Thin film resistor and fabrication method thereof
A resistor is formed between devices in an integrated circuit by forming a patterned trench in an intralayer dielectric (ILD) deposited over the devices, filling the trench with polysilicon and planarizing the polysilicon. The resistance of the resistor is defined by determining and selecting the size and form of the trench including the width, length, depth and orientation of the trench. In some embodiments, the resistance of the resistor is also controlled by adding selected amounts and species of dopants to the polysilicon. In some embodiments, the resistance is controlled by directly saliciding the polysilicon in the trench.
