Abstract

Official abstract text for this publication.

There is provided a substrate processing apparatus which includes: a process container configured to accommodate a substrate; a partition member disposed between plasma generated inside the process container and the substrate, the partition member configured to selectively transmit radicals in the plasma toward the substrate; and a heat shield plate disposed between the partition member and the substrate. The heat shield plate is disposed so as to face the substrate. The heat shield plate is made of metal or silicon and is connected to the process container.

First claim

Opening claim text (preview).

What is claimed is: 1 . A substrate processing apparatus, comprising: a process container configured to accommodate a substrate; a partition member disposed between plasma generated inside the process container and the substrate, the partition member configured to selectively transmit radicals in the plasma toward the substrate; and a heat shield plate disposed between the partition member and the substrate, wherein the heat shield plate is disposed so as to face the substrate, the heat shield plate being made of a metal and being connected to the process container. 2 . The apparatus of claim 1 , wherein the heat shield plate constitutes a portion of the process container. 3 . The apparatus of claim 2 , wherein both the heat shield plate and the process container are made of aluminum or an aluminum alloy. 4 . The apparatus of claim 1 , wherein the heat shield plate has a plurality of ejection ports formed therein to eject a process gas toward the substrate. 5 . The apparatus of claim 1 , wherein the heat shield plate has a radical passage penetrating in a thickness direction, the radical passage having a cross-sectional shape increasing in diameter toward the substrate. 6 . The apparatus of claim 1 , wherein the heat shield plate is covered with a dielectric material. 7 . The apparatus of claim 6 , wherein the dielectric material is composed of a yttrium compound or silicon. 8 . A substrate processing apparatus, comprising: a process container configured to accommodate a substrate; a partition member disposed between plasma generated inside the process container and the substrate, the partition member configured to selectively transmit radicals in the plasma toward the substrate; and a heat shield plate disposed between the partition member and the substrate, wherein the heat shield plate is disposed so as to face the substrate, the heat shield plate being made of silicon and being connected to the process container. 9 . A heat shield plate disposed between a partition member, which is disposed between plasma and a substrate and configured to selectively transmit radicals in the plasma toward the substrate, and the substrate, wherein the heat shield plate is disposed so as to face the substrate, and the heat shield plate is made of a metal. 10 . A heat shield plate disposed between a partition member, which is disposed between plasma and a substrate and configured to selectively transmit radicals in the plasma toward the substrate, and the substrate, wherein the heat shield plate is disposed so as to face the substrate, and the heat shield plate is made of silicon.
