摘要： A semiconductor light-emitting device includes a plurality of semiconductor rods, each of which has a pn junction. The semiconductor rods are formed on a semiconductor substrate such that the plurality of semiconductor rods are arranged at a distance substantially equal to an integer multiple of the wavelength of light emitted from the semiconductor rod. With such devices, various novel optical devices such as a micro-cavity laser of which the threshold current is extremely small and a coherent light-emitting device having no threshold value can be realized.

摘要： This invention discloses a heterojunction type field effect transistor such as 2DEG-FET and a heterojunction type bipolar transistor such as 2DEG-HBT. The former is fabricated by applying to the formation of its source and drain regions a technique which causes the disorder of the heterojunction by intoduction of an impurity such as by ion implantation or a technique which causes the disorder of the heterojunction by forming a film made of at least one kind of material selected from insulators, metals and semiconductors which have a different linear coefficient of thermal expansion from that of the material of a semiconductor substrate on the heterojunction semiconductor region which is to be disordered. The latter is fabricated by applying either of the techniques described above to a base ohmic contact region. These semiconductor devices can reduce the source-gate resistance and the parasitic base resistance. The invention discloses also the structure of the ohmic contact layer which has a trench on the surface thereof and is particularly effective for reducing the source-gate parasitic resistance.

摘要： A solid film forming apparatus, e.g., an MO-MBE (Metal-Organic Molecular Beam Epitaxy) apparatus, wherein evacuatable containers isolated from a growth chamber by a switching device and connected to raw material gas introduction pipings are provided between the growth chamber for a solid film, e.g., a compound semiconductor, and raw material gas introduction pipings. Growth of the solid film is controlled by opening and closing the switching device and evacuating the container at least while the switching device is closed during the growth of the solid film. An undesired influence on the growing film due to residual gas in the containers which are not used for growth can be prevented and, hence, interception and introduction of the raw material gas into the growth chamber can be performed with remarkably high controllability, and films of superior abruptness of the interface between films, e.g., the heterojunction of the compound semiconductor, can be obtained.

摘要： The present invention relates to a semiconductor laser which oscillates in a single longitudinal mode and with a low threshold current and which exhibits a good mode stability against reflected light, and provides a structure of a distributed feedback semiconductor laser with modulation for a gain. The structure is such that gain producing regions are periodically arranged and that a substance transparent to laser radiation is buried between the regions. A layer including the gain regions is formed of a superlattice layer, and an impurity is diffused or implanted into periodic positions of the layer, whereby the transparent regions and the gain regions with little lattice damages can be readily formed.
