According to an embodiment of the present invention, in the thin film electrode forming method as defined in Claim 25, a degree of the vacuum in the evacuation step is within a range of 1�10−1 to 3�10−3 pascals.
According to an embodiment of the present invention, in the thin film electrode forming method, a degree of the vacuum in the second evacuation step is within a range of 1�10−1 to 3�10−3 pascals.
Initially, the support 81 is placed in a vacuum chamber, and thereafter is subjected to a vacuum evacuation as far as a prescribed degree of vacuum (this can be within a range of 1�10−1 to 3�10−3 pascals). Thereafter, when the vacuum chamber is filled up with an inert gas (the degree of vacuum after the filling is within a range of approximately 0.1 to 10 pascals), and a high-frequency voltage of approximately 0.01 to 5 KV is applied thereto, the inert gas is excited and ionized, and is slammed onto the surface of the support 81. These ions have high kinetic energies, and enough surface roughening effects can be obtained by the high-frequency voltage application in quite a short period of time (approximately 0.1 to 10 seconds). Further, similar surface roughening effects can be obtained not only by the high-frequency voltage application but also by a DC voltage application or the like.
Like in the surface roughening processing for the surface of the support 81, it is subjected to the vacuum evacuation to a prescribed degree of vacuum (it can be within a range of 1�10−1 to 3�10−3 pascals). Thereafter, the vacuum chamber is filled up with an inert gas (the degree of vacuum after the filling is within a range of approximately 0.1 to 10 pascals), and a high-frequency voltage of approximately 0.01 to 5 KV is applied thereto, whereby the inert gas is excited and ionized. The ionized gas is collided against a target plate composed of a conductive material, whereby atoms of the conductive substance are beaten out and then deposited as a film on the support 81, thereby forming a thin film electrode layer. It is also possible that the vacuum evacuation is performed and thereafter the conductive substance is heated and evaporated so as to be deposited as a film on the support 81, thereby forming a thin film electrode layer. A typical one of the former manufacturing method is the sputtering evaporation, and a typical one of the latter is the vacuum evaporation.
