A lighting dome that can be used to inspect semiconductor wafers can include a small aperture, backlighting, a reflectance gradient andor a broad spectrum light source. The semiconductor package includes a substrate; a semiconductor element having opposite active and inactive surfaces and disposed on the substrate via the active surface thereof, wherein the inactive surface of the semiconductor element is roughened; a thermally conductive layer bonded to the inactive surface of the semiconductor element; and a heat sink disposed on the thermally conductive layer. A signal processing circuit periodically samples a dose signal, corresponding to an X-ray dose per unit of time, from the detection pixels. The liquid-pipe is disposed at the base. A torsion spring is connected to the first guide member and oriented about the second guide member for locking the second guide member relative to the first guide member. Data related to the purchaser is correlated at point of purchase with the unique identifier and stored in a database for latter retrieval upon theft or loss.
