摘要： A non-leaded semiconductor device comprises a sealing body for sealing a semiconductor chip, a tab in the interior of the sealing body, suspension leads for supporting the tab, leads having respective surfaces exposed to outer edge portions of a back surface of the sealing body, and wires connecting pads formed on the semiconductor chip and the leads. End portions of the suspension leads positioned in an outer periphery portion of the sealing body are unexposed to the back surface of the sealing body, but are covered with the sealing body. Stand-off portions of the suspending leads are not formed in resin molding. When cutting the suspending leads, corner portions of the back surface of the sealing body are supported by a flat portion of a holder portion in a cutting die having an area wider than a cutting allowance of the suspending leads, whereby chipping of the resin is prevented.

摘要： Reduction in reliability of a semiconductor device is suppressed. A semiconductor device includes a plurality of metal patterns formed on a ceramic substrate, and a plurality of semiconductor chips mounted on the plurality of metal patterns. Also, the plurality of metal patterns include metal patterns MPH and MPU which face each other. In addition, a region which is provided between these metal patterns MPH and MPU and which is exposed from the plurality of metal patterns extends so as to zigzag along an extending direction of the metal pattern MPH.

摘要： A non-leaded semiconductor device comprises a sealing body for sealing a semiconductor chip, a tab in the interior of the sealing body, suspension leads for supporting the tab, leads having respective surfaces exposed to outer edge portions of a back surface of the sealing body, and wires connecting pads formed on the semiconductor chip and the leads. End portions of the suspension leads positioned in an outer periphery portion of the sealing body are unexposed to the back surface of the sealing body, but are covered with the sealing body. Stand-off portions of the suspending leads are not formed in resin molding. When cutting the suspending leads, corner portions of the back surface of the sealing body are supported by a flat portion of a holder portion in a cutting die having an area wider than a cutting allowance of the suspending leads, whereby chipping of the resin is prevented.

摘要： Reduction in reliability of a semiconductor device is suppressed. A semiconductor device includes a plurality of metal patterns formed on a ceramic substrate, and a plurality of semiconductor chips mounted on the plurality of metal patterns. Also, the plurality of metal patterns include metal patterns MPH and MPU which face each other. In addition, a region which is provided between these metal patterns MPH and MPU and which is exposed from the plurality of metal patterns extends so as to zigzag along an extending direction of the metal pattern MPH.
