The invention provides a unique method and apparatus for removing flash or other contaminants from an electronic package such as encapsulated semiconductor device by exposing the device to plasma gas. In a preferred embodiment, a plasma gas cleaner is provided with a reaction chamber used to house the encapsulated device during a deflashing procedure. Plasma gas is supplied to the reaction chamber for reaction on the surfaces of the device. The reaction of the plasma on these surfaces successfully removes excess encasing material and other contaminants. The plasma gas cleaner may be a plasma gas device used for other process steps (e.g., plasma etching) employed during the fabrication and manufacture of the semi conductor device.
