One aspect of the present invention relates to an integrated circuit package that includes multiple layers of a planarizing, photo-imageable epoxy that are formed over a substrate. In some designs, the substrate is a silicon wafer. An integrated circuit is embedded in the epoxy. An antenna, which is electrically coupled to the active face of the integrated circuit through an interconnect layer, is formed over one of the epoxy layers. In various embodiments, at least some of the epoxy layers are positioned between the substrate and the antenna such that there is a distance of at least approximately 100 microns between the substrate and the antenna.

A laser beam temporally modulated in amplitude by a modulator and shaped into a long and narrow shape by a beam shaper is rotated around the optical axis of an image rotator inserted between the beam shaper and a substrate. Thus, the longitudinal direction of the laser beam having the long and narrow shape is rotated around the optical axis on the substrate. In order to perform annealing in a plurality of directions on the substrate, the laser beam shaped into the long and narrow shape is rotated on the substrate while a stage mounted with the substrate is moved only in two directions, that is, X- and Y-directions. In such a manner, the substrate can be scanned at a high speed with a continuous wave laser beam modulated temporally in amplitude and shaped into a long and narrow shape, without rotating the substrate. Thus, a semiconductor film can be annealed.
