Title: Exposure system
Inventor: UENO MASATOSHI
IPC: G03F7/20
Filed: 1993-06-04
Abstract: PURPOSE:To surely closely bring a substrate into contact with an original plate without causing the retaining of air. CONSTITUTION:By elevating a vacuum frame 456 and lifting the end parts of a flexible mask plate 310, the plate 310 is projectingly curved and bent with respect to the substrate K. When the plate 310 is forcibly curved in such a way, the capacity of an airtight chamber 317 formed of a pallet seal material 434 around the substrate K and a pattern film PF is increased while the airtight state thereof is maintained and the pressure thereof can be made negative. Besides, air in the chamber 317 is sucked through the sucking hole 315 of the plate 310 almost at the same time that the pressure of the chamber 317 is made negative. Thus, the substrate K is closely brought into contact with the film PF at the projecting part at first. Then, the closely contacted area between the substrate K and the film PF is radially and rapidly enlarged from the projecting part thereafter. Therefore, the substrate K is surely closely brought into contact with the film PF to the end parts from the center thereof and both of them are closely brought into contact with each other extending over the whole surface.

The heated liquid is sent to the reactor 5 filled with iron particles and made to contact with the iron particles. The iron particles are corroded with the H2S and HCN in the absorption liquid, and the absorption liquid is introduced into the distillation column 6 and the reboiler 7. The distilled out H2S is transferred to the sulfuric acid production process, and the remaining absorption liquid is recycled to the absorption column 2 through the heat exchanger 4 and the filter 8. The corrosivity of the absorption liquid is measured by the monitor 9, and when it is increased, the iron particles are changed.
