Provided is a substrate processing apparatus. The substrate processing apparatus includes a reaction tube; a heating device configured to heat the reaction tube; and a manifold installed outward as compared with the heating device and made of a non-metallic material. A first thickness of the manifold defined in a direction perpendicular to a center axis of the reaction tube is greater than a second thickness of the manifold defined at a position adjacent to the reaction tube in a direction parallel to the center axis of the reaction tube. The manifold includes a protrusion part of which at least a portion protrudes inward more than an inner wall of the reaction tube, and a gas supply unit disposed at at least the protrusion part for supplying gas to an inside of the reaction tube.

The sizes required for maintenance are reduced and an occupying floor area is reduced. The substrate processing apparatus contains a load lock chamber 41 and a transfer chamber 24 respectively provided in order from the rear side within a case 11; and a processing chamber 53 provided above the load lock chamber 41 for processing wafers 1. An opening section 27A, and an opening and closing means 28A for opening and closing the opening section 27A are respectively provided in a location at the rear side of the transfer chamber 24 where the load lock chamber 41 is not arranged.

This oxide for a semiconductor layer of a thin-film transistor contains Zn, Sn and In, and the content (at %) of the metal elements contained in the oxide satisfies formulas (1) to (3) when denoted as [Zn], [Sn] and [In], respectively. [In]/([In]+[Zn]+[Sn])≧−0.53×[Zn]/([Zn]+[Sn])+0.36 (1) [In]/([In]+[Zn]+[Sn])≧2.28×[Zn]/([Zn]+[Sn])−2.01 (2) [In]/([In]+[Zn]+[Sn])≦1.1×[Zn]/([Zn]+[Sn])−0.32 (3) The present invention enables a thin-film transistor oxide that achieves high mobility and has excellent stress resistance (negligible threshold voltage shift before and after applying stress) to be provided.
摘要:
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.
