Lighting device and lighting method

A lighting device comprising first and second groups of solid state light emitters, which emit light having dominant wavelength in ranges of from 430 nm to 480 nm and from 600 nm to 630 nm, respectively, and a first group of lumiphors which emit light having dominant wavelength in the range of from 555 nm to 585 nm. If current is supplied to a power line, a combination of (1) light exiting the lighting device which was emitted by the first group of emitters, and (2) light exiting the lighting device which was emitted by the first group of lumiphors would, in an absence of any additional light, produce a sub-mixture of light having x, y color coordinates within an area on a 1931 CIE Chromaticity Diagram defined by points having coordinates (0.32, 0.40), (0.36, 0.48), (0.43, 0.45), (0.42, 0.42), (0.36, 0.38).

Preparation of metal silicon nitride films via cyclic deposition

This invention relates to an improved process for producing ternary metal silicon nitride films by the cyclic deposition of the precursors. The improvement resides in the use of a metal amide and a silicon source having both NH and SiH functionality as the precursors leading to the formation of such metal-SiN films. The precursors are applied sequentially via cyclic deposition onto the surface of a substrate. Exemplary silicon sources are monoalkylamino silanes and hydrazinosilanes represented by the formulas: (R1NH)nSiR2mH4-n-m (n=1,2; m=0,1,2; n+m=<3); and (R32N—NH)xSiR4yH4-x-y (x=1,2; y=0,1,2; x+y=<3) wherein in the above formula R1-4 are same or different and independently selected from the group consisting of alkyl, vinyl, allyl, phenyl, cyclic alkyl, fluoroalkyl, silylalkyls.
