Abstract: PURPOSE:To contrive the reduction of internal strain generating by impurity doping by a method wherein the growing temperature is restricted to a specific range of temperature in growing an Si-doped GaAs active layer on a GaAs substrate. CONSTITUTION:An n type AlGaAs layer 2 is grown on an n type GaAs substrate 1, and the Si-doped GaAs active layer 3 is grown on this layer 2 at a temperature within a range of 840-940 deg.C. Thereafter, a p type AlGaAs layer 4 is grown on the layer 3. This layer 3 is doped with Si at a high concentration in order to obtain a desired band of infrared wavelength. However, the doping of high concentration impurities into a semiconductor region produces strains in a crystal lattice on account of the difference in size between the atom constituting the mother crystal and the impurity atom. A growing temperature of 840-940 deg.C can be used as a condition for the epitaxial growth of high concentration SiGa in order to inhibit said strain.

Abstract: PURPOSE:To realize high speed operation with a simple constitution for wide address input information, by selecting whether address information is inputted with positive polarity or negative polarity in an AND circuit for address decoding according to the contents stored in a storage element. CONSTITUTION:Address information is inputted in an input line 10, and a storing timing signal 19 is converted to a signal 12-1, etc., by a storing circuit 18. The signal 12-1 is supplied to a gate for transistors(TR) 20 and 21, and the address information is stored in a storage element 29. TRs 22 and 23 are turned on by the next inputted storing timing signal 19, and address definition information on an address input line 10-1 is stored in a storage element 30. The above operation is simultaneously performed for each bit on the address input line. By repeating the same operation by times to be defined, the definition process for all addresses is finished. Since an address conversion opration, which is normally performed by a software, is performed by a hardware, higher speed operation can be realized.

Abstract: PURPOSE:To form a thin film on a substrate while preventing the deposition of the thin film on an optical window by setting the light intensity on the inside surface of the optical window provided to a thin film forming chamber at the intensity enough to evaporate the thin film sticking to said optical window and introducing the light from said optical window into the thin film forming chamber. CONSTITUTION:The light is introduced through the optical window 22 into the thin film forming chamber (vacuum chamber) 21 and the thin film is formed while a reactive gas or substrate 31 is photoexcited. The light intensity on the inside of the window 22 is maintained substantially higher to evaporate the thin film depositing to the window 22, by which the decrease of incident light is prevented. The light intensity necessary for the evaporation of the thin film is approximately calculated from the wavelength region of the light, the magnitude of the absorption of the thin film in said wavelength region and the temp. necessary for the evaporation of the thin film. Whether the light is pulse light or continuous light is an important parameter as well. These parameters are easily obtd. from a physical property constant chart, etc.
