NOVELTY - Thin film valve device comprises: chamber containing fluid for biological assay; sample injection element; channel (10c) that connects chamber(s) and allows fluid flow; hole (10, 10a, 10b) in middle of channel to interconnect upper and lower portions of channel; thin film valve (60) coated with adhesive (61a) that closes hole; substrate (2) including channel, hole and chamber(s); thin film adhesive tape that binds substrate(s); body formed by binding substrate(s) using thin film adhesive tape; and heat generating apparatus that radiates heat onto thin film valve.    USE - As a thin film valve device for performing biological or biochemical assay (claimed) i.e. a diagnostic assay device for detecting trace amount of materials in fluid.    ADVANTAGE - The thin film valve device smoothly controls flow and flow rate of fluid, by including thin film valve control apparatus, in which holes and valves that are bonded to holes by thin film adhesive are opened and closed with heat generated from heat generating device in addition to centrifugal force as thin film valve device rotates; as compared to prior art devices that can not overcome difficulty of constructing thin film type structure and do not ensure precise control of the flow rate i.e. devices having electromagnet valve that generate excess heat due to consumption of large amount of electricity, and are not suitable as thin film valve. In opening hole, adhesive strength of adhesive is lowered by heat generated from heat generating apparatus, and then stopple or the thin film adhesive tape is separated from hole by hydraulic force of fluid, generated due to centrifugal force. Thus volume of external magnets is reduced, and reliability of opening valves is ensured. As thin film valve device allows closing and opening of hole by stopple coated with adhesive or thin film adhesive tape attached to hole, it tightly closes hole for period of circulation, and avoids gap formation in bio-disc that causes evaporation of fluid and lowers reliability of valve sealing. In addition, adhesive used as coating agent for thin film valves is flexible to adapt to expansion and shrinking of body of thin film valve device, with temperature, and prevents the problem of sealing. As the valves are thin film valves, larger number of valves can be integrated in a unit area. Also, fluid does not contact valves, as holes instead of channels are opened. Thus, properties of fluid are less likely to be changed as heat is generated. The thin film valve device is applicable in constructing valves and their control apparatus for diagnostic lab-on-a-chip and rotatable bio-disc as micro valve devices on CD-ROM and DVD.    DETAILED DESCRIPTION - A thin film valve device comprises: at least one chamber that stores a fluid required for biological or biochemical assay and in which a biological or biochemical reaction is performed; a sample injection element for injecting a sample; a channel (10c) that connects at least one chamber and through which the fluid moves; a hole (10, 10a, 10b) located in the middle of channel and interconnects upper and lower portions of channel; a thin film valve (60) that closes the hole and is coated with an adhesive (61a); at least one substrate (2) including channel, hole and at least one chamber; a thin film adhesive tape that binds at least one substrate together; a body formed by binding at least one substrate using thin film adhesive tape and in which channel, hole, at least one chamber, sample injection element, and thin film valve are integrated; and a heat generating apparatus that radiates heat onto thin film valve. The hole is opened by weakening adhesive strength of adhesive by using heat generated from heat generating apparatus, with magnetic force and/or centrifugal force generated as body rotates to separate thin film valve from hole. The channel is a thin film channel formed by thin film adhesive tape. The substrate comprises stacked upper, intermediate and lower substrates, and body is assembled with thin adhesive tape on substrate. The thin film adhesive tape forms hole closing film around hole and substrate binding portion. The hole closing film is formed of thermoplastic adhesive (preferably hot melt adhesive), and substrate binding portion is formed of thermosetting adhesive film (preferably acrylic adhesive). The thermosetting adhesive has softening temperature of greater than or equal to 120 degrees C, and thermoplastic adhesive has softening temperature of 60-80 degrees C. The thin film valve is selected from bead (ball) stopple (61b), heat shrinkable stopple, nonmagnetic stopple, magnetic stopple, and hole closing film formed of thin film adhesive tape. The nonmagnetic stopple is formed of metallic material in form of cylindrical thin film or donut-shaped thin film. The magnetic stopple is formed of magnetic material or permanent magnetic material in form of cylindrical thin film or a donut-shaped thin film; where magnetic material has Curie point (Curie temperature) higher than softening point of adhesive. The thin film valve comprises reversible opening/closing function that involves opening hole closed by magnetic stopple by weakening adhesive strength of magnetic stopple using heat generated from heat generating apparatus and then using magnetic force exerted as result of moving permanent magnet located under body toward center of hole; and closing hole again by restoring adhesive strength of magnetic stopple by using optionally heat generated from heat generating apparatus and then by moving permanent magnet located under hole away from center of hole so that magnetic force of permanent magnet disposed over hole is exerted on magnetic stopple to close hole. The thin film valve is closed for period of circulation due to magnetic force of permanent magnet disposed above hole and adhesive strength of adhesive. The body further comprises wireless radio frequency integrated circuit (RFIC), or a solar battery for supplying power to wireless RFIC. An INDEPENDENT CLAIM is included for a thin film valve control apparatus comprising: the thin film valve device; spindle motor that rotates thin film valve device; slider that moves heat generating apparatus and permanent magnet, where heat generating apparatus and permanent magnet are mounted on slider; slide motor that controls movement of slider in radial direction; and central control unit that controls operation of heat generating apparatus, slide motor and spindle motor and performs spatial addressing with respect to thin film valve, such that the holes in thin film valve device are selectively opened and closed.
