Patent ID: 8281741

Claim:
A plasma deposition apparatus, comprising: a chamber; a pedestal placed in the chamber; a plasma generator placed in the chamber and over the pedestal, wherein the plasma generator comprises a plasma jet for plasma thin film deposition having a discharge direction angle θ 1 larger than 0° and less than 90° between a normal direction of the pedestal and the discharge direction of the plasma jet; and a gas-extracting pipe extending into the chamber and over the pedestal, wherein the gas-extracting pipe provides a pumping path for pumping particles and side-products having a pumping direction angle θ 2 larger than 0° and less than 90° between the normal direction of the pedestal and the pumping direction of the gas-extracting pipe, wherein the chamber is kept at an ambient atmospheric pressure, and wherein the gas-extracting pipe and the plasma generator have a moving direction parallel to the pedestal.
