Embodiments of the invention generally provide a method for depositing films using photoexcitation. The photoexcitation may be utilized for at least one of treating the substrate prior to deposition, treating substrate and / or gases during deposition, treating a deposited film, or for enhancing chamber cleaning. In one embodiment, a method for depositing silicon and nitrogen-containing film on a substrate includes heating a substrate disposed in a processing chamber, generating a beam of energy of between about 1 to about 10 eV, transferring the energy to a surface of the substrate; flowing a nitrogen-containing chemical into the processing chamber, flowing a silicon-containing chemical with silicon-nitrogen bonds into the processing chamber, and depositing a silicon and nitrogen-containing film on the substrate.

A method of preventing or reducing fogging of a surface of a composite when subjected to humid conditions includes providing a composite with a surface. The composite includes a substrate and a photocatalytic surface layer. The photocatalytic surface layer includes a photocatalyst. The method further includes subjecting the photocatalyst to photoexcitation to render the surface of the composite hydrophilic, wherein, after the photoexcitation, the surface of the composite has a water wettability of less than 10° in terms of the contact angle with water. The method further includes subjecting the composite to humidity that is sufficient to induce fogging of the substrate if the photocatalytic surface layer were absent.

A multi-gate structure is used and a width (d1) of a high concentration impurity region sandwiched by two channel forming regions in a channel length direction is set to be shorter than a width (d2) of low concentration impurity regions in the channel length direction. Thus, a resistance of the entire semiconductor layer of a TFT which is in an on state is reduced to increase an on current. In addition, a carrier life time due to photoexcitation produced in the high concentration impurity region can be shortened to reduce light sensitivity.

A phototherapy or photobiomodulation process employing the application of electromagnetic radiation (EMR) to a living organism, typically a human being. The EMR is generated by one or more strings of LEDs and is programmed to emit one or more wavelengths, typically in the visible and infrared portions of the spectrum, the EMR in each wavelength being delivered in pulses having specified on-times, off-times, photoexcitation frequencies, duty factors, phase delays, and power amplitudes. A system for providing such EMR includes a microcontroller having a pattern library of algorithms, each of which defines a particular sequence of synthesized pulses, and an application pad, preferably flexible, containing the LED strings.

To provide a sol of modified metal-oxide composite colloidal particles which are almost completely inhibited from being discolored by photoexcitation, contain titanium oxide excellent in light resistance and weatherability, and have a high refractive index. [MEANS FOR SOLVING PROBLEMS] The modified metal-oxide composite colloidal particles comprise: titanium oxide / tin oxide / zirconium oxide / tungsten oxide composite colloidal particles (A) which have a primary-particle diameter of 2-50 nm and have an SnO2 / TiO2 molar ratio of 0.1-1.0, ZrO2 / TiO2 molar ratio of 0.1-0.4, and WO3 / TiO2 molar ratio of 0.03-0.15, as cores; and tungsten oxide / tin oxide / silicon dioxide composite colloidal particles (B) having a primary-particle diameter of 1-7 nm with which the surface of each core has been coated.

Disclosed is a measuring apparatus for a physical phenomenon by photoexcitation, in particular a delay time modulated and time-resolved, scanning probe microscope apparatus providing an ultimate resolution both temporal and spatial. The apparatus comprises an ultrashort laser pulse generator (2); a delay time modulating circuit (6) which splits an ultrashort laser pulse (3) produced by the ultrashort laser pulse generator (2) into two and which also modulates a delay time td between the two ultrashort laser pulses (4 and 5) with a frequency (ω); a scanning probe microscope (7); and a lock-in detection unit (8) which performs lock-in detection with the delay time modulation frequency (ω) of a probe signal (11) from the scanning probe microscope (7). It can detect the delay time dependency of the probe signal (11) as its differential coefficient to the delay time, with no substantial influence from fluctuations in the intensity of ultrashort laser pulses (3) while preventing the probe apex (19) from thermal expansion and shrinkage by repeated irradiation with ultrashort laser pulses (3). A photoexcited physical phenomenon dependent on a delay time between ultrashort laser pulses can thus be measured at a temporal resolution in the order of femtoseconds and at a spatial resolution in the order of angstroms.
