Abstract:
There are provided a substrate placing plate and a substrate processing apparatus using the substrate placing plate. The substrate processing apparatus comprises a process chamber configured to accommodate a substrate and perform a heat treatment on the substrate; and a substrate transfer machine configured to carry the substrate into the process chamber in a state where the substrate is placed on a substrate placing plate. The substrate placing plate comprises at least three substrate placing parts. The substrate placing parts are located on the same horizontal plane, and in a state where the substrate placing parts are located at a top side of the substrate placing plate, top surfaces of the substrate placing parts are higher than a surface of the substrate placing plate surrounded by the substrate placing parts and are higher than all peripheral surfaces of the substrate placing parts.
Abstract:
A CVD device has a reaction furnace (39) for processing a wafer (1); a seal cap (20) for sealing the reaction furnace (39) hermetically; an isolation flange (42) opposite to the seal cap (20); a small chamber (43) formed by the seal cap (20), the isolation flange (42), and the wall surface in the reaction furnace (39); a feed pipe (19b) for supplying a first gas to the small chamber (43); an outflow passage (42a) provided in the small chamber (43) for allowing the first gas to flow into the reaction furnace (39); and a feed pipe (19a) provided downstream from the outflow passage (42a) for supplying a second gas into the reaction furnace (39). Byproducts such as NH4Cl are prevented from adhering to low temperature sections such as the furnace opening and therefore the semiconductor device production yield is therefore increased.

A thermal treatment furnace for use with a semiconductor system is provided. The thermal treatment furnace includes a scavenger which sealingly encloses a lower end of a reaction tube so as to diminish gas leakage from the reaction tube.
Abstract:
Stagnation of gas used for substrate processing in an exhaust trap is prevented, and localized precipitation of components in the gas used for substrate processing is reduced. The proposed apparatus includes a substrate processing chamber (cylindrical space 250), a gas supply tube 232 for supplying substrate processing gas to the substrate processing chamber, a first exhaust tube (upstream exhaust tube 231a) for discharging gas used for substrate processing from the substrate processing chamber, an exhaust trap 49 for removing components contained in the gas used for substrate processing introduced through the first exhaust tube, and a second exhaust tube (downstream exhaust tube 231b) for exhausting gas out of said exhaust trap 49 after components have been removed from the gas used for substrate processing, wherein the exhaust trap 49 is provided with a cooled baffle plate 59 that is substantially perpendicular to the direction in which gas is introduced into the exhaust trap 49 and that has a concave surface 59a in the side facing the gas introduction port 55a of the exhaust trap 49.

A substrate processing apparatus includes a substrate container holding shelf comprising a plurality of shelf boards configured to hold substrate containers thereon; a substrate container carrying mechanism configured to load and unload the substrate containers into/from the substrate container holding shelf; a substrate container holding shelf elevation mechanism configured to lift each of the plurality of the shelf boards of the substrate container holding shelf in a vertical direction; and a processing unit configured to receive at least one of the substrate containers from the substrate container holding shelf.
Abstract:
A substrate processing apparatus, wherein a flowing direction of a gas flow which has flown upwardly and ascended in an inner tube (3A) is changed at an upper portion of the inner tube (3A) so as to be flown between the inner tube (3A) and an outer tube (2A) and exhausted outwardly, comprising: an inner tube cap 11 suited for covering the upper portion of the inner tube (3A); gas passages provided between the upper portion of the inner tube (3A) and the inner tube cap (11); and the inner tube cap (11) having a central portion protruded into an upstream of the gas flow. According to the substrate processing apparatus thus configured and a method of manufacturing a semiconductor device using the substrate processing apparatus, it is possible to prevent a reaction product from being deposited on a ceiling portion of an outer tube as well as being deposited as particles on a processing or processed substrate or substrates disposed in the inner tube. Further, it is possible to smoothly deflect the direction of a gas flow so as to allow the substrate to be uniformly processed with a high quality.
Abstract:
A plurality of airtight chambers are connected through blocking means, which can communicate or shut off the chambers, and at least one of the airtight chambers is used as a processing chamber. One of the adjacent airtight chambers is replaced by a replacement gas, and the replacement gas is supplied to the other of the adjacent airtight chambers. When pressure difference or pressure in the two adjacent airtight chambers is below a predetermined value, the adjacent two airtight chambers are communicated, and pressure in the two airtight chambers is equalized.
