Abstract

The is to disclose a semiconductor package featuring inclusion of light emitter(s) providing light to indicate the states of the semiconductor package as a whole and/or the chip(s) therein. The light emitter is in an original state or flashing state or emitting state according to the states of the semiconductor package as a whole and/or the chip(s). The semiconductor package includes a carrier and a shield structure in addition to the light emitter. The chip and at least part of the carrier are covered by the shield structure. The light emitter may be partially or fully covered or sealed by the shield structure. The light emitter may also be partially or fully exposed. The shield structure is such that the light provided by the light emitter sealed therein can pass therethrough to reach the outside thereof, thereby the states of the semiconductor package as a whole and/or the chip(s) can be recognized from the outside of the semiconductor package.
