Abstract: PROBLEM TO BE SOLVED: To raise whiteness degree by improving developing sensitivity by a method wherein 1,1-bis(4-hydroxyphenyl)-3,3,5-trimethylcyclohexane is contained as an electron acceptive developing compound in a heat sensitive coloring layer. SOLUTION: Though the content of 1,1-bis(4-hydroxyphenyl)-3,3,5- trimethylcyclohexane is not especially limited, it is contained within a range of generally 30-600 pts.wt., preferably 150-300 pts.wt. to 100 pts.wt. of dye precursor. When the content is less than 30 pts.wt., an effect for improvement of sensitivity is not sufficient. When it is more than 600 pts.wt., a problem on tailing and sticking is apt to be generated. It can be independently used, or used jointly with another electron acceptive developing compound. Well-known urea compound or organic acid material of multi-valent metal salt or the like is exemplified therefor. As an electron donative developing dye precursor constituting a heat sensitive coloring layer, it can be selected in well-known material such as triaryl series or the like.

Abstract: PURPOSE:To improve inverse characteristics without deteriorating the characteristics in normal direction, by making hole open to the surface of an insulating film, providing a barrier metal layer on an exposed Si-substrate, and making  a rim-contacting Si-layer a high resistant or inactive layer. CONSTITUTION:A slope 11 is made by opening a hole 3a to SiO2 2a on an N type Si-substrate 1, and etching with solution of (pure water):HF=1:30. A Pt film 6 is evaporated. A barrier metal 4 of Au-Si alloy is made afer a proper heat treatment. Next, the accelerating voltage, dose, and the like are selected after B-ion implantation. The metal layer 4 does not pass through before reaching the substrate 1 because of a thin film of the slope. A high-resistant P<-> or N<-> or electrically inactive layer 7 is made after heat treatment and activation. The layer 7 does not enter under the rim of barrier metal 4. And so, an effective area of Schottky barrier diode does not decrease. The existence of layer 7 relieaves field concentration at the rim of layer 4 at inverse bias. The good inverse characteristics can be obtained without decrease of normal characteristics. The increase of area is very little.
