The present invention proposes to form first a trench contract of relatively large size, then to form one or more dielectric layer(s) within the trench contact, and then to remove the upper part of the dielectric layer(s) and to fill the same with a conductive material. The use of such a method makes it easy to form a trench contact of relatively large size which is easy for manufacturing; besides, since dielectric layer(s) is/are formed in the trench contact, thence capacitance between a source/drain trench contact and a gate electrode is reduced accordingly.

    Abstract: A semiconductor structure includes a chip, a plurality of metal posts disposed in the chip and a buffer layer disposed on the chip. The chip includes a silicon-based layer having opposite first and second surfaces, and a build-up structure formed on the first surface of the silicon-based layer consisting of at least a metal layer and a low-k dielectric layer alternatively stacked on one another. Each of the metal posts is disposed in the silicon-based layer with one end thereof electrically connected with the metal layer while the other end is exposed from the second surface of the silicon-based layer. The buffer layer is disposed on the build-up structure. By positioning the low-k dielectric layer far from the second surface that is used for connecting to an external electronic component, the present invention reduces the overall thermal stress.

    Abstract: A semiconductor device is made by forming a first conductive layer over a sacrificial carrier. A conductive pillar is formed over the first conductive layer. An active surface of a semiconductor die is mounted to the carrier. An encapsulant is deposited over the semiconductor die and around the conductive pillar. The carrier and adhesive layer are removed. A stress relief insulating layer is formed over the active surface of the semiconductor die and a first surface of the encapsulant. The stress relief insulating layer has a first thickness over the semiconductor die and a second thickness less than the first thickness over the encapsulant. A first interconnect structure is formed over the stress relief insulating layer. A second interconnect structure is formed over a second surface of encapsulant opposite the first interconnect structure. The first and second interconnect structures are electrically connected through the conductive pillar.
