Industrial-scale production of diiodosilane through reaction between phenylsilane and iodine is safely and efficiently performed. Provided is a diiodosilane producing method wherein reaction is started between phenylsilane and iodine at a low temperature, the method including at least the step of, after dropping and mixing step finishes, pumping a reaction solution little by little continuously while raising a temperature thereof.

Diiodosilane producing method

A screen printing method comprises an aligning process for fixing a master plate (10) to a fixing frame (20) in aligned relation thereto, an exposure process of exposing a screen printing plate (50) through the master plate (10) fixed to the fixing frame (20), a developing process for developing the thus exposed screen printing plate (50), and a printing process for printing a workpiece (80) by using the thus developed screen printing plate (50). In the aligning process, the positioning pins (22a, 22b, 22c) of the fixing frame (20) abut against the positioning protuberances (62a, 62b, 62c) of a fixing block (61). In the exposure process, the positioning pins (22a, 22b, 22c) of the fixing frame (20) abut against the positioning protuberances (32a, 32b, 32c) of a positioning block (3), while the positioning pins (52a, 52b, 52c) of the printing plate (51) holding the screen printing plate (50) abut against the positioning protuberances (62a, 62b, 62c) of the fixing block (61). In the printing process, the positioning pins (52a, 52b, 52c) of the plate frame (51) holding the screen printing plate (50) abut against the positioning protuberances (72a, 72b, 72c) of a fixing block (71). With this arrangement, the aligned state established by the aligning process which is performed first of all is maintained throughout until the last printing process is completed.
