摘要： An infrared sensor is formed with a first infrared detecting element for infrared detection disposed in a container through a supporting substrate, and a second infrared detecting element for temperature compensation also disposed in the container to be shielded by the supporting substrate of the first infrared detecting element from incident infrared within the container, while a temperature sensing section of the first infrared detecting element is born in non-contacting state with respect to a supporting part of the substrate for the element, whereby the sensitivity can be remarkably improved with a simpler arrangement while keeping a high precision and inexpensiveness.

摘要： An electron source 10 has an n-type silicon substrate 1, a drift layer 6 formed on one surface of the substrate 1, and a surface electrode 7 formed on the drift layer 6. A voltage is applied so that the surface electrode 7 becomes positive in polarity relevant to the substrate 1, whereby electrons injected from the substrate 1 into the drift layer 6 drift within the drift layer 6, and are emitted through the surface electrode 7. In a process for manufacturing this electron source 10, when the drift layer 6 is formed, a porous semiconductor layer containing a semiconductor nanocrystal is formed in accordance with anodic oxidation. Then, an insulating film is formed on the surface of each semiconductor nanocrystal. Anodic oxidation is carried out while emitting light that essentially contains a wavelength in a visible light region relevant to the semiconductor layer.

摘要： A field emission-type electron source 10 includes an insulative substrate 11 in the form of a glass substrate having an electroconductive layer 8 formed thereon. A strong electrical field drift layer 6 in the form of an oxidized porous polycrystalline silicon layer is formed over the electroconductive layer 8. This electroconductive layer 8 includes a lower electroconductive film 8a, made of copper and formed on the insulative substrate 11, and an upper electroconductive film 8b made of aluminum and formed over the electroconductive film 8a. The strong electrical field drift layer 6 is formed by forming a polycrystalline silicon layer on the electroconductive layer 8, rendering the polycrystalline silicon layer to be porous and finally oxidizing it. The upper electroconductive film 8b has a property that reacts easily with silicon and, therefore, formation of an amorphous layer which would occur during formation of the polycrystalline silicon layer can be suppressed.

摘要： An electron source (10) has an electron source element (10a) including a lower electrode (12), a drift layer (6) and a surface electrode (7). The drift layer (6) is interposed between the lower electrode (12) and the surface electrode (7). When a certain voltage is applied between the surface electrode (7) and the lower electrode (12) such that the surface electrode (7) has a higher potential than that of the lower electrode (12), a resultingly induced electric field allows electrons to pass through the drift layer (6) and then the electrons are emitted through the surface electrode (7). When a forward-bias voltage is applied between the surface electrode (7) and the lower electrode (12), a reverse-bias voltage is applied after the forward-bias voltage has been applied to release out of the drift layer (6) an electron captured by a trap (9) in the drift layer (6).
