Title: SEMICONDUCTOR DEVICE WITH A PROTECTED ACTIVE DIE REGION AND METHOD THEREFOR
Abstract:
A semiconductor device (10) includes a semiconductor die (16) having a plurality of contact pad sites, a plurality of contact pads (20-26), an encapsulant barrier (18), and an encapsulant (30). A plurality of contact pads is in electrical contact with a predetermined corresponding different one of the contact pad sites. An encapsulant barrier (18) is positioned at an outer perimeter of the semiconductor die. The encapsulant barrier has a height that is as high as or greater than a highest of the plurality of contact pads. The encapsulant barrier is in physical contact with a same surface of the semiconductor die as the contact pad sites. An encapsulant (30) surrounds the semiconductor die and one side of the encapsulant barrier. The encapsulant is blocked from making physical contact with any of the plurality of contact pads by the encapsulant barrier when the device is encapsulated while being supported by a temporary base support layer.
