Zusammenfassung: | A thermal physical vapor deposition source for depositing material onto a substrate includes an elongated container for receiving the material, the container having a conductance CB in the elongated direction, and a heater for heating the material in the container to vaporize the material to a partial pressure Pm. The container has at least one member defining a plurality of apertures arranged along the length of the member, the apertures having a total conductance CA, wherein Formula (I) and end heaters for heating each side of the container to reduce condensation of material onto the container. |
