  • Patent number: 10049955
    Abstract: A fabrication method of a semiconductor package includes the steps of: forming a release layer on a carrier having concave portions; disposing chips on the release layer in the concave portions of the carrier; forming an encapsulant on the chips and the release layer; forming a bonding layer on the encapsulant; removing the release layer and the carrier so as to expose the active surfaces of the chips; and forming a circuit structure on the encapsulant and the chips. Since the release layer is only slightly adhesive to the chips and the encapsulant, the present invention avoids warpage of the overall structure during a thermal cycle caused by incompatible CTEs.

    Abstract: An apparatus and method are disclosed for forming thin films on a semiconductor substrate. The apparatus in one embodiment includes a process chamber configured for supporting the substrate, a gas excitation power source, and first and second gas distribution showerheads fluidly coupled to a reactive process gas supply containing film precursors. The showerheads dispense the gas into two different zones above the substrate, which is excited to generate an inner plasma field and an outer plasma field over the wafer. The apparatus deposits a material on the substrate in a manner that promotes the formation of a film having a substantially uniform thickness across the substrate. In one embodiment, the substrate is a wafer. Various embodiments include first and second independently controllable power sources connected to the first and second showerheads to vary the power level and plasma intensity in each zone.
