Abstract: PURPOSE:To increase the reliability of the semiconductor device by perforating a contact hole by utilizing a photosensitizer at the semiconductor substrate provided with a protective film, retaining the photosensitizer, evaporating the base metal, then removing the photosensitizer and retaining the base metal only in the contact hole. CONSTITUTION:The protective film formed of oxide films 2, 4 and a phosphorus glass film 6 is formed on the semiconductor substrate 1, the photosensitizer 7 is coated thereon, and contact holes 8 are perforated at the parts corresponding to source, drain and gate. The base conductors 11, 11' such as Si, Mo, Ti, V or the like are evaporated in the state that the photosensitizer 7 is retained, the photosensitizer 7 is removed to retain the base conductor only in the contact holes 8, and wire conductors are formed in a predetermined pattern to make contact therewith. Thus, since the protective film for covering the substrate is not eroded unevently, then protecting function is not lowered, but the semiconductor device having high reliability can be obtained.

Title: Compound semiconductor element
Inventor: KONDO MASAHIKO
IPC: H01S5/00
Filed: 1990-01-16
Abstract: PURPOSE:To improve the crystal quality of a hetro interface and further enhance the characteristics of an element by using a dopant having no dependence on the inclination of doping efficiency in terms of a compound semiconductor element formed an on inclination substrate. CONSTITUTION:If an attempt is made to adopt Si of group IV atoms which enter a group III site given in the periodic table of atoms, there will be no marked difference in the doping efficiency with a GaAs layer and an AlInP layer. Furthermore, the element will not be subjected to the inclination from a (100) plane. The application of Si2H6, which is a raw material gas of Si as an n-type dopant, can improve the characteristics of AlGaInP based on semiconductor elements, which use an inclination substrate having an (n11)A plane. On an (n11)B plane inclined to the direction of [0-11], there is an atomic arrangement where the group III site and the group V site of the (n11)A plane are exchanged from each other. Therefore, the adoption of the dopant which enters the group V site in stead of the dopant which enters the group III site, can eliminate the inclination dependence of doping efficiency.

Title: Optical demultiplexer
Inventor: SUZUKI KATSUNORI
IPC: G02F1/09
Filed: 1988-01-14
Abstract: PURPOSE:To constitute an optical demultiplexer of high isolation by providing a Farady element, which is worked and controlled to such thickness that the difference of Farady rotation angle between two wavelengths is 90 deg., a pair of polarized light separating elements arranged on both sides of the Farady element, and a permanent magnet which gives an external magnetic field to the Farady element. CONSTITUTION:The angular difference between a Farady rotation angle thetaf1 for a wavelength lambda1 and a Farady rotation angle thetaf2 for a wavelength lambda2 is set to 90 deg.. Consequently, when the light having wavelengths lambda1 and lambda2 is made incident, only a certain linearly polarized component passes a first polarized light separating element 2 and the light having wavelengths lambda1 and lambda2 is converted to linearly polarized components orthogonal to each other by the Farady element, and the light having the wavelength lambda1 and the light having the wavelength lambda2 are separated from each other by a second polarized light separating element 8. At this time, the isolation is determined by isolations of polarized light separating elements 2 and 8 and the Farady element 4, and >=40dB is easily obtained with respect to polarized light separating elements, and about 37dB is obtained with respect to the Farady element. Thus, the optical demultiplexer of high isolation is obtained.

Filed: 1990-01-11
Abstract: PURPOSE:To monitor the operational state of a fan without requiring manual operation by constituting an apparatus in such manner that an abnormality- detecting means outputs an abnormality signal when a rotation-detecting means outputs a stop detection signal. CONSTITUTION:If the rotation of a fan 6 stops due to any accident when a driving switch 7 is ON, light emanated from a light-emitting part 10 is continuously received by a light-receiving part 11 or continuously cut OFF by a blade 6a and a light-receiving circuit 12 outputs a high-level stop detection signal S12b or low-level stop detection signal S12c. Further, because an operating signal S8 is inputted from an operating circuit 8, an arithmetic circuit 13 calculates the duration of the stop detection signal S12b or S12c and outputs a high-level abnormality detection signal S13 when the duration reaches a set time T. Thus, a display lamp 16 is lighted and a buzzer 17 alarms to inform that the fan 6 has stopped.

When the graphic elements are added to the data DR, the corresponding DC is just extracted out of the file 11 and has not to be supplied each time. Furthermore the data DR can be processed based on the old DC despite the replacement of the DC within the file 11 since both the DC and the DR are stored in the file 200.
