    Abstract: PROBLEM TO BE SOLVED: To prevent occurrence of point defects (multiple voids) or laminate defects such as crystal twin, etc., caused in thin films to improve quality as well as enable lower temperature treatment and simplification of the manufacturing method. SOLUTION: A glass substrate 2 on which a rear-surface electrode 3 is formed is disposed in a vacuum tank 7 and a Cuα(InxGa1-x)β(SeyS1-y)γ thin film 4 is formed on the rear-surface electrode 3 on the glass substrate 2 by vapor- depositing or sputtering Cu, In, Ga, Se and S from a supply source 8. At this time, steam is irradiated onto the rear-surface electrode 3 on the glass substrate 2 from a supply source 9 to supply water or hydroxy group. Anion voids generated during the formation of the thin film are filled with oxygen so that generation of anion voids and multiple voids of cation-anion are prevented and the density of the twins correlating with anion voids is reduced.

    Abstract: PURPOSE:To detect the condition of the deposit on a plate or the condition of the plate without contact by setting the incident angle of the diagonal incident acoustic wave on the plate, the frequency of the acoustic wave and the thickness of the plate, exciting the plate wave propagating in the plate and detecting the above-mentioned condition from the change of the excitation state of the plate wave. CONSTITUTION:One side face of a housing 6 is formed of the plate 5 having the parallel front and rear. A wave transmitting element 8 is so disposed that the acoustic wave We emitted therefrom is reflected by the plate 5 and arrives at a wave receiving element 9. The relations among the incident angle of the wave We on the plate 5, the frequency of the wave We and the thickness of the plate 5 are adjusted and the plate wave propagating in the plate 5 is excited. The propagation speed of the plate wave is designated as Cp, the speed of the wave We in the liquid 7 as Cl and the incident angle of the wave We as theta, then the plate wave is excited in the plate 5 if the conditions Cl=Cp.sintheta are satisfied. The change of the excitation state of the plate wave is detected by an indicator 12, by which the detection of the sticking or contacting of the liquid and solid matter in addition to the detection of the deposition and settlement of powder are made possible. The discrimination of the characteristics of the sticking material and deposit is made possible. The corroding condition of the plate 5 is inspected as well by using the plate 5 as a material to be inspected and scanning the surface thereof with the acoustic wave.
