Abstract:
A semiconductor device of the ball grid array type comprising:a bare chip and metal-filled through hole portions connected to internal electrodes of said bare chip, each internal electrode being on said bare chip and within an area defined by said bare chip including an inner portion located at one end of the electrode, an outer portion located at another end of the electrode and an intermediate portion located between the inner portion and the outer portion; andsaid internal electrodes including a first set of internal electrodes arranged perpendicularly to a first side of said bare chip and at a predetermined pitch in a direction along the first side of the bare chip, said internal electrodes including a second set of internal electrodes arranged perpendicularly to a second side of said bare chip and at the predetermined pitch in a direction along the second side of the bare chip, said first side being transverse to said second side,one of said through hole portions being connected to one of the inner portions of the first set of internal electrodes, one of said through hole portions being connected to one of the intermediate portions of the first set of internal electrodes and one of said through hole portions being connected to one of the outer portions of the first set of internal electrodes so that said through hole portions are arranged in a staggered pattern,a plurality of outer electrodes provided on said device outside said area defined by said bare chip;an inner lead from the intermediate portion of said internal electrode being spaced apart from an adjacent through hole portion by such a distance as not to interfere with said adjacent through hole; andan outer lead that electrically connects one of said internal electrodes with one of said outer electrodes.
