摘要:
A sensor with built-in circuits can be improved in the stability of the operation or characteristics. A circuit region and a sensor region are covered by a passivation film. The sensor region is partially covered by the passivation film. The sensor region and circuit region are protected by the passivation film, and an effect of the passivation film on the mechanical displacement of a diaphragm portion can be alleviated so that the sensor with built-in circuits may be improved in the stability of the operation or characteristics.

摘要:
A process for producing a hard roll for use as an elastic roll for making paper calendering by casting a liquid thermosetting resin material into a space between a metal roll core and an outer mold, and thereafter heating the resin material from outside to cure a major portion of the material and to form an outer layer resin intermediate body, while cooling the resin material from the roll core side to leave a viscount liquid resin material layer inside the intermediate body. The intermediate body is subsequently cooled from outside the outer mold to contract the body, allowing an excess of the liquid material to be forced out upwardly with the contraction of the body. The material is thereafter heated from the roll core side to cure the remaining viscous liquid resin material. The hard roll can be produced without cracking due to the reaction contraction and thermal shrinkage of the thermosetting resin. The roll is usable without cracking in its surface hardness despite the influence of heat. The process is reduced in the number of steps and improved in production efficiency to ensure a low production cost.

摘要:
An improved arrangement is provided for forming a bipolar transistor on a substrate with CMOS elements. All of the transistors (i.e., the bipolar, P-MOS and N-MOS) are formed in regions having gradually decreasing impurity concentrations from the surface toward the substrate. In addition, a buried layer is provided under each of the regions of decreasing impurity concentration in which the transistors are formed. These buried layers have a significantly higher impurity concentration than the portion of the region of decreasing impurity concentration which they are respectively adjacent to. Using this arrangement, punch-through is prevented and excellent electrical operating characteristics are provided for both the bipolar transistors and the CMOS elements.

A semiconductor device includes a plurality of semiconductor regions of a first conductive type and a plurality of semiconductor regions of a second conductive type. AMOS transistor having a channel of the second conductive type is formed in the semiconductor regions of the first conductive type, and a bipolar transistor and a MOS transistor having a channel of the first conductive type are formed in the semiconductor regions of the second conductive type. Each of the semiconductor regions of the first conductive type is made up of a semiconductor layer where the impurity concentration decreases with the depth from the surface thereof, a first buried layer of the first conductive type which is formed in a semiconductor substrate and where the impurity concentration distribution in the direction of thickness has a single peak value, and a second buried layer of the first conductive type which is formed between the semiconductor layer and the first buried layer and where the impurity concentration distribution in the direction of thickness has a single peak value. The first and second buried layers are formed by the ion implantation method, after an epitaxial growth process and a field oxidation process have been completed.
