Abstract:
1. A method of manufacturing a semiconductor package, the package including a surface for attachment of the package to a device by a joint formed of a connective material in a joint area of the surface, the method comprising the steps of: patterning one or more channels on the surface, which channels extend away from the joint area towards an edge of the surface, the joint area to be disposed between the surface of package and the device; applying a compound into said one or more channels which compound interacts with the connective material, such that when the semiconductor package is attached to the device the interaction defines one or more paths in the connective material which correspond to the one or more channels on the surface and which allow the passage of waste material away from the joint area to the outer edge of the surface; and introducing a strengthening element into the or each channel, wherein the channel has two elongate sides and the strengthening element is introduced at a point between the two sides to prevent relative movement thereof.
