The interface apparatus includes: a correcting circuit which corrects the deadline time of the request data according to the timing when the request data has been submitted, thereby generating corrected deadline time information; a header generator which generates a packet header that stores the corrected deadline time information; and a packetizing processor which generates a request packet based on the request data and the packet header.

Abstract: First, at least one of silanol and a siloxane compound is generated in a chlorosilane (S101). In the step, for example, an inert gas having a moisture concentration of 0.5 to 2.5 ppm is brought into contact with the chlorosilane to dissolve the moisture, and at least one of silanol and a siloxane compound is generated through a hydration reaction of a moiety of the chlorosilane. Next, a boron-containing compound contained in the chlorosilane is reacted with the silanol or the siloxane compound, thereby converting the boron-containing compound to a boron oxide (S102). Through the step (S102), the boron-containing compound being a low boiling point compound is converted to a boron oxide being a high boiling point compound, and therefore the difference in boiling point from the boiling point of chlorosilane becomes larger to make later separation easy.

Abstract: The present invention provides a technique which allows stable use of an ion-exchange resin for removing boron impurities over a long period of time in the purification step of a silane compound or a chlorosilane compound. In the present invention, a weakly basic ion-exchange resin used for the purification of a silane compound and a chlorosilane compound is cleaned with a gas containing hydrogen chloride. When this cleaning treatment is used for the initial activation of the weakly basic ion-exchange resin, a higher impurity-adsorbing capacity can be obtained. Further, use of the cleaning treatment for the regeneration of the weakly basic ion-exchange resin allows stable use of the ion-exchange resin for a long time. This allows reduction in the amount of the resin used in a long-term operation and reduction in the cost of used resin disposal.
