摘要:
The invention aims at increasing an effect of a strain applying technique for enhancing transistor performance in a fully depleted silicon-on-insulator (FDSOI) type transistor having a thin buried oxide (BOX) film. In an FDSOI type transistor having a very thin SOI structure (6), a stress generating region is formed on a back face side (5) of a very thin BOX layer (4) in order to apply strains to portions in which channels are intended to be formed. Desired portions on a back face side of the BOX layer (4) are amorphized by performing ion implantation, and are then recrystallized by performing a heat treatment in a state where a stress applying film (3) is formed, thereby transferring stresses from the stress applying film (3) to the portions in which the channels are intended to be formed. Thus, the stress generating region is formed.

To provide TFT of improved low-temperature polycrystalline layer that has higher electron mobility and assures less fluctuation in manufacture in view of realizing a liquid-crystal display device having a large display area by utilizing a glass substrate. A TFT having higher electron mobility can be realized within the predetermined range of characteristic fluctuation by utilizing the semiconductor thin-film (called quasi single crystal thin-film) formed of poly-crystal grain joined with the {111} twin-boundary of Diamond structure as the channel region (namely, active region) of TFT.

At least one of a semiconductor thin-film for forming a picture display portion and a semiconductor thin-film for forming a peripheral circuit portion, which are accumulated on one common insulative substrate, is constructed with a semiconductor thin-film having a plural number of semiconductor crystalline portions formed to be divided and disposed in a matrix-like, and TFTs are provided in the semiconductor thin-film by bringing those semiconductor single crystal portions into active portions thereof. For that purpose, a crystallization accelerating material is adhered at the position of lattice points of a matrix and is treated with heating process, for forming the single crystal portions disposed in the matrix-like manner, so as to form the TFTs on the surface thereof, thereby completing the thin-film semiconductor integrated circuit device.

Configurations of a light signal communication apparatus and an optical communication system suitable for speeding-up of the transmission of information based on a light signal and an increase in the capacity for the information transmission are disclosed. On the light signal transmitting side, excitation light is supplied to an active medium in accordance with a transmission signal to cause induced emission within the active medium, thereby generating signal light. The excitation light causes spontaneously-emitted light to fall on a semiconductor layer, and a voltage pulse corresponding to transmission information is applied to modulate the refractive index of the semiconductor layer, thereby Bragg-reflecting a specific wavelength component, after which it is sent to the active medium as the excitation light. The Bragg reflection and induced emission incident to it exhibit excellent response to a voltage signal having a pulse width of 1×10−9 seconds or less. It is therefore possible to implement an optical communication system having a transmission rate up to 100 Gb/s with one light signal.
