    • A package for a semiconductor device and a method for packaging a semiconductor device are disclosed. The semiconductor package uses a tape which allows for the production of packaged semiconductor devices having different contact patterns. The contact pattern is configured to the required pin contact pattern by varying the number and placement of balls on the bottom of the tape. In one embodiment, the tape includes bonding pads and an array of contact pads. Each bonding pad is connected to one of the contact pads, and an opening is disposed in the tape below each contact pad. A semiconductor device is connected to the tape and is electrically connected to the bonding pads. The semiconductor device is then sealed on the top and sides by a plastic top which attaches to the tape. Balls are then selectively attached to the tape such that they electrically connect to select contact pads so as to form a desired contact pattern. Packages having different contact patterns are easily formed by altering the number and position of balls deposited on the tape. Thus, a single tape may be used for forming packaged semiconductor devices having different contact patterns. Thus, significant cost savings is realized since different tapes need not be fabricated for each different contact pattern.
    • 公开了一种用于半导体器件的封装以及用于封装半导体器件的方法。 半导体封装使用允许生产具有不同接触图案的封装半导体器件的带。 通过改变磁带底部的球的数量和位置,将接触图形配置成所需的针接触图案。 在一个实施例中,带包括接合焊盘和接触焊盘阵列。 每个接合焊盘连接到接触焊盘中的一个,并且在每个接触焊盘下面的带中设置一个开口。 半导体器件连接到带并且电连接到接合焊盘。 然后,半导体器件在顶部和侧面通过粘附到带的塑料顶部密封。 然后将球选择性地附接到带,使得它们电连接到选择接触垫,以形成期望的接触图案。 具有不同接触图案的包装通过改变沉积在带上的滚珠的数量和位置而容易地形成。 因此,可以使用单个带来形成具有不同接触图案的封装半导体器件。 因此,由于不需要为每个不同的接触图形制造不同的带,所以实现了显着的成本节省。
