    摘要: A field effect transistor has the property that the product of its active total series resistance and its true transconductance is less than one throughout the entire range of drain voltage in the operative state of this transistor, the active total series resistance being the sum of the active resistance from source to channel, the active resistance of this channel and the active resistance from channel to drain. In order to prevent an excessive increase in the active resistance of the channel, the channel is made to have an impurity concentration as low as less than 10.sup.15 atoms/cm.sup.3, preferably less than 10.sup.14 atoms/cm.sup.3, so that the depletion layers extending from the gates grow extensively to become contiguous in such fashion in response to a small increase in the reverse gate voltage applied, that no narrow lengthy path is formed between the depletion layers. As a result, the field effect transistor of this invention has an unsaturated drain current versus drain voltage characteristic.

    摘要: In a method of epitaxially growing a compound crystal, a plurality of crystal component gasses of a compound and reaction gas chemically reacting with the crystal component gasses are individually directed, in the predetermined order, onto a substrate crystal heated under vacuum. The crystal compound gasses and the reaction gas may be overlapped with each other. In a doping method in the above-described epitaxial growth method, the crystal component gasses and the compound gas of dopant are directed onto the substrate crystal and, subsequently, reaction gas, which chemically reacts with the compound gasses, is directed onto the substrate crystal. Also in this case, the reaction gas may be in overlapped relation to the component gas of dopant.

    摘要: In performing a solution growth of a Group II-VI compound semiconductor crystal by relying on the temperature difference technique under controlled vapor pressure on a solution growth apparatus having a recrystallizing zone, a source crystal supply zone and a vapor pressure controlling zone enclosed in a growth quartz tube and placed under different temperatures for the respective zones, wherein a heat sink is provided at the bottom end portion of the recrystallizing zone to cause a thermal flow to pass therethrough to the outside of the whole apparatus to insure that a single crystal will grow from this bottom end portion of the zone. The quartz tube may be enclosed in a pressure-resistant tube to apply a pressure to the growth quartz tube externally thereof to avoid its destruction to enable the growth to be performed at a high temperature to obtain a high growth rate. Thus, a large size crystal having a good crystal perfection can be grown.

    摘要: A tunnel injection controlling type semiconductor device comprising a source semiconductor region having a certain conductivity type for supplying carriers, a drain semiconductor region for receiving the carriers, and a gate electrode for controlling the flow of these carriers. A highly-doped semiconductor region having a conductivity type opposite to that of the source semiconductor region is provided in contact with the source region or contained locally in the source region to cause tunnel injection of carriers. The potential level of this highly-doped region is varied by virtue of the static induction effect exerted by the voltage applied to the gate electrode which is provided at a site close to but separate from the highly-doped region, and to the drain semiconductor region.
