A heat treating apparatus comprises a reaction tube for receiving a plurality of articles to be treated and a heating unit surrounding at least part of the reaction tube. The reaction tube comprises a first structural section, at least part of which is surrounded by the heating unit and a second structural section, at least part of which extends from the heating unit. The first structural section is made of material having thermal resistivity and thermal conductivity higher than the second structural section.

Heat treating apparatus

A clean air apparatus includes a housing having an opening through which a carrier housing semiconductor wafers is supplied into the housing and an I/O port for supporting the carrier and a furnace for treating the wafer, provided in the upper portion of the housing. The carriers are at the same time supported by a first carrier stage provided in the upper portion of the housing and supported by a second carrier stage provided in the lower portion of the housing. The carrier or carriers are selectively moved between the I/O port and the first stage, between the I/O port and the second stage, and between the first stage and the second stage. A clean air is applied to the wafers in the carriers supported by the I/O port, the first stage and the second stage.

Clean air apparatus

A vertical heating apparatus comprises a casing having an opening through which a plurality of transport members receiving articles to be processed are loaded in and unloaded from the casing, a heat treating furnace provided in an upper portion of the casing, a transport member storing portion provided in the casing at a side space of the heat treating furnace, for receiving the transport members, a processing member for transporting the articles to be processed in the heat treating furnace, a transferring mechanism for transferring the articles to be processed and received by the transport members to the processing member, and a vertically moving mechanism provided below the heat treating furnace in the casing, for loading and unloading the articles to be processed and received by the processing member in and from the heat treating furnace.
