Abstract:
The present invention provides toner for an electrostatic latent image developer, said toner being excellent in fluidity, chargeability, developability, transferability, and freedom from fogging on a photoreceptor and contamination of the interior of a developing device. The toner for an electrostatic latent image developer comprises spherical toner particles characterized by a shape index ML.sup.2 /A of less than 125 and has a correlation coefficient between X.sup.2/3 and Y, obtained by linear regression with respect to a straight line which passes through the origin of coordinate axes, of more than 0.6 where X is the light emitting voltage due to the carbon derived from the binder resin of the toner particles and Y is the light emitting voltage due to the element derived from the external additive.

Abstract:
Electronic devices are provided with electrically conductive interconnections which are formed on the insulator material. Such electronic devices include, for example, thin film semiconductor devices (TFT), metal-insulator-metallic type non-wiring elements (MIM), solar cells, Large Scale Integration devices (LSI) or printed-wiring boards. At least a part of the electrically conductive interconnections are made of .alpha.-structure tantalum (Ta) which contains hydrogen. The .alpha.-structure tantalum does not have cubical crystals in its crystal system, but rather has body-centered cubes (bcc). The resistivity of the .alpha.-structure tantalum is from about 20 .mu..OMEGA. centimeters to about 60 .mu..OMEGA. centimeters. When hydrogen is included within this .alpha.-structure tantalum film, small amounts of nitrogen may be contained along with the hydrogen in the film. When a semiconductor layer is directly formed on the lower conductive layer, the upper conductive layer contains, as a primary component, the hydrogen contained .alpha.-structure tantalum.
