发明名称 Method and apparatus for directing molding compound flow and resulting semiconductor device packages
摘要 Flow diverting structures for preferentially impeding, redirecting or both impeding and redirecting the flow of flowable encapsulant material, such as molding compound, proximate a selected surface or surfaces of a semiconductor die or dice during encapsulation are disclosed. Flow diverting structures may be included in or associated with one or more portions of a lead frame, such as a paddle, tie bars, or lead fingers. Flow diverting structures may also be inserted into a mold in association with semiconductor dice carried on non-lead frame substrates, such as interposers and circuit boards, to preferentially impede, redirect or both impede and redirect the flow of molding compound flowing between and over the semiconductor dice.
