Abstract: A method of fabricating a semiconductor device with improved quality and an encapsulant are provided. The method may include coating a chip wafer including a plurality of semiconductor chips with an encapsulant, performing a pre-curing process to bring the encapsulant into a B-stage, dicing the chip wafer to divide the chip wafer into a plurality of semiconductor chips, forming a chip stack by stacking the semiconductor chip on the base wafer in such a way that a coupling electrode on the base wafer and a bump electrode of each of the semiconductor chips face each other with a conductive adhesive element interposed therebetween, performing a reflow process on the chip stack under pressurized gas to bond the coupling electrode and the bump electrode to each other with the conductive adhesive element interposed therebetween, and performing a post-curing process on the chip stack under pressurized gas to bring the encapsulant into a C-stage.

Abstract: An apparatus for testing an object includes a moving unit configured to hold and move the object. A transmissive illuminating unit includes a light source generating light and a transmissive mask pattern. The transmissive mask pattern includes a first region configured to convert the light generated from the light source into a slit light, and a second region arranged in a movement direction of the object with respect to the first region to partially transmit the light generated from the light source. The transmissive illuminating unit is configured to project a measuring light, which is provided by transmitting the light generated from the light source through the transmissive mask pattern, to the object. A detecting unit is configured to receive a reflected light of the measuring light from the object and to detect a height and surface state of the object based on the reflected light.
