Abstract: PURPOSE:To maintain moistureproofness and humidity resistance and to prevent crack in a semiconductor package by applying a humidity resistant polymer thin film of a specific thickness by plasma polymerization uniformly and homogeneously on the semiconductor and attaining the adhesion of the uniform and the package surface. CONSTITUTION:Concerning a semiconductor package 30, a humidity resistant or moistureproof polymer thin film is uniformly and heterogeneously coated on the surface except the soldered part 17a of the outer lead part 17 by plasma polymerization. The thickness of the polymer thin film 39 is as thin as 10 to 500nm. Such a very thin film can be only attained by plasma polymerization. But when the thickness is thinner than 10nm, the moistureproofness is not satisfactory, and when the thickness exceeds 500nm, the productivity deteriorates and the polymer film thickness at the border between the masking tape and the leads becomes too thick. The thickness is preferable to be in a range between 10 and 50nm.

Abstract: PURPOSE:To provide a process and an apparatus for producing a plasma- polymerized film of good quality without decreasing the rate of film formation and injuring the surface of a substrate or of the plasma-polymerized film and to produce a plasma-polymerized film excellent in especially water vapor barrier properties, while preventing the formation of double bonds due to recombination of residual radicals and the formation of polar groups due to oxidation both of which occur especially when the plasma-polymerized film is withdrawn into air after polymerization. CONSTITUTION:An excited monomer gas generated by plasma generation sources 4 and 6 is led toward the direction of a substrate 12 set in the polymerization apparatus along a guide cylinder 18 provided around the periphery of plasma generation sources 4 and 6 to form a plasma-polymerized film on the surface of the substrate 12. After a plasma-polymerized film is formed on the surface of a substrate in a sealed container 8, a hydrogen gas is fed to the sealed container to replace the atmosphere in the container by a hydrogen gas atmosphere, and the substrate on which a plasma-polymerized film is formed is withdrawn from the container after a given time.

Abstract: PURPOSE:To enhance a humid-proof characteristic of a package by a method wherein the surface of the package composed of resins is coated with a humid- proof resin film. CONSTITUTION:The surface of a package 7 composed of resins is coated with a humid-proof characteristic resin film 8. That is, a semiconductor is mounted on a semiconductor device mount tray within a chamber for coating to supply gaseous humid-proof resins to a coating chamber, whereby the surface of the package 7 composed of the resins is coated with the humid-proof characteristic resin film 8. Thus, a humid-proof characteristic of the package 7 rises, and a time capable of mounting the semiconductor device under a normal temperature and a normal humidity can be prolonged while the package is unpacked and mounted. Moreover, reliability for a long interval after mounted is enhanced.

Abstract: PURPOSE:To make a steam sensor possible to fast respond to changes in the amount of steam even in a low humidity area by using a plasma polymerization film made of spheroidal carbons (fullerene) as detector. CONSTITUTION:A plasma polymerization film made of spheroidal carbons used for a detector is an organic semiconductive thin film which is made of a compound as given by a formula of Cn (n: integer allowing the formation of a spheroidal compound geometrically) or (Cn+j) m (n: as mentioned above, j: integer of -10-10, m: positive integer). The compound has a structure in which a plurality of spheroidal carbons are polymerized by 1, 2-cycle bond added to a cyclohexatrienyl site and in the thin film, the structure is distributed in an amorphous state. The plasma polymerization film made of the spheroidal carbons is low in conductivity in the environment where no steam exists. When the steam exists, the conductivity increases 100,000 times at its maximum. The film has quick susceptibility with a high sensitivity.
