Abstract: In CVD processes susceptors can be made of a thermally conductive ceramic such as aluminum nitride which has superior durability with respect to fluorine plasma. Such aluminum nitride susceptors can include an embedded heater element and/or embedded ground or RF electrodes which as a result of their embedment are protected from the deleterious effects of the processing chamber environment. The conductors leading to these elements are protected from exposure to the process chamber environment by passing through a cylindrical member filled with inert gas supporting the wafer support plate of said susceptor. Alternately, the conductors leading to these elements can be run through passages in a hermetically sealed stem supporting the susceptor wafer support plate. The stem passes through the wall of the processing chamber so that connections to the susceptor wafer support plate can be made outside the processing chamber.

Abstract: An all-plastic drum construction permits a variety of sizes and capacity of drum by utilizing an extruded tube for the drum side walls of selected diameter and length proportional to the drum capacity desired. An injection molded bottom closure is welded to the bottom end of the tube by a thermoplastic bonding material having dispersed iron particles which are excited when exposed to induction heating thereby facilitating the melting of the thermoplastic. This welding material is disposed within a cavity defined by the bottom closure and bottom end of the tube and when subjected to induction heating and pressure fills the cavity to effectuate the bond between surfaces of the bottom closure and bottom end of the tube. A tight head drum is formed by securing by a similar welding technique a top closure to the upper end of the tube. In forming an open head drum, a thermoplastic chime is initially welded in similar fashion to the upper end of the tube.

Abstract: A closure is provided for a container opening. The opening is defined by a neck extending outwardly from the top of the container. The closure includes a liner cap disposed both interiorly and exteriorly of the neck and defines a central passage. A plug extends across the top of the cap to close off the passage from the exterior. The plug is provided with at least one longitudinal hole. The lower end of the plug has attached thereto a membrane extending across the passage. This membrane does not permit liquids within the container to pass therethrough, but possesses the property of being capable of venting gasses therethrough. A dust cap may extend across the top of the closure during shipment and storage.
