Since the lead wire 9 is exposed as described above, there is a concern that the product may be deteriorated due to external contamination, and if a cutting deviation occurs during dicing, the lead wire which should be originally separated remains connected and a short circuit occurs. However, the yield will decrease. Further, due to a problem caused by the exposed lead wires coming close to each other, the user's requirement for the distance between the lead wires and the arrangement on the front and back sides of the substrate is strongly demanded, and the degree of freedom in design is suppressed.

Further, until now, a short circuit of a pattern in the substrate state could not be detected because it was electrically independent for each package in the final shape after dicing, but according to the invention of the present application. Since each package is electrically independent, it is possible to detect in the stage before the assembly process by performing an electrical test before mounting the semiconductor element, and it is also possible to improve the efficiency of the assembly process by removing defective products. It will be possible. Further, since the slit 10 is formed in the substrate 1, it is possible to reduce the warp amount of the substrate 1.

In this embodiment, the slit shape is not particularly mentioned, but the slit width needs to be wider than the dicing area width. That is, the slit width is the dicing area width + the amount of bite into the package (the distance from the end of the bonding pad (lead wire) in the final shape to the resin cross section). In terms of processing, it is preferably 0.5 mm or more, and even if it is too wide,
Not preferable in terms of production efficiency. Currently, a general dicing area width is 0.2 to 0.3 mm, and for example, the distance (overhang amount) from the center of the ball formed on the ball pad on the back surface to the resin cross section is 0.75 to 1. About 3 mm is usually applicable range, but if the overhang amount is set to 0.75 mm and the margin is set to 0.5 mm, the bite can be up to 0.25 mm on one side, and the slit width is 0.7 to 0.8 mm. Can be That is, the distance from the end of the lead wire, which is the end of the bonding pad, to the cross section of the resin can be 0.25 mm or more, and a sufficient effect can be obtained against external contamination.
