SUBSTRATE PROCESSING APPARATUS AND SUBSTRATE PROCESSING METHOD
First Claim
1. A substrate processing apparatus for carrying out etching as plasma processing on a substrate, comprising a processing chamber in which the substrate is housed, a stage that is disposed in said processing chamber and on which the substrate is mounted, and at least one processing gas introducing unit that introduces a processing gas into said processing chamber;
- wherein said processing gas introducing unit is a projecting body that projects out into said processing chamber, and has therein a plurality of processing gas introducing holes that open out in different directions to one another.

Abstract
A substrate processing apparatus that enables a state of plasma over a substrate to be maintained in a desired state easily. A plasma processing apparatus 10 that has therein a camber 11, a stage 12, and a processing gas introducing nozzle 38 carries out etching on a wafer W. The chamber 11 houses the wafer W. The stage 12 is disposed in the chamber 11 and the wafer W is mounted thereon. The processing gas introducing nozzle 38 is a projecting body that projects out into the chamber 11, and has therein a plurality of processing gas introducing holes 56 that open out in different directions to one another.

8. A substrate processing method implemented by a substrate processing apparatus for carrying out etching as plasma processing on a substrate, including a processing chamber in which the substrate is housed, and at least one processing gas introducing unit that introduces a processing gas into the processing chamber, wherein the processing gas introducing unit is a projecting body that projects out into the processing chamber, and has therein a plurality of processing gas introducing holes that open out in different directions to one another, the processing gas introducing holes being divided into at least two processing gas introducing hole groups;
- the substrate processing method comprising;
independently controlling a flow rate of the processing gas introduced into the processing chamber by each of the processing gas introducing hole groups.
- the substrate processing method comprising;
