The second interposer substrate is disposed over the first interposer substrate and includes a second conductive via and a second dielectric layer. The second conductive via is bonded to the first conductive via, and the second dielectric layer is bonded to the first dielectric layer. The semiconductor die is disposed over the composite interposer and is electrically coupled to the first conductive via and the second conductive via.

Abstract: A method of fabricating a floating gate includes providing a substrate divided into a cell region and a logic region. A silicon oxide layer and a silicon nitride layer cover the cell region and the logic region. Numerous STIs are formed in the silicon nitride layer, the silicon oxide layer, and the substrate. Later, the silicon nitride layer within the cell region is removed to form one recess between the adjacent STIs within the cell region while the silicon nitride layer within the logic region remains. Subsequently, a conductive layer is formed to fill the recess. The conductive layer is thinned to form a floating gate.

Abstract: A method of fabricating a through silicon via structure includes the following steps. At first, a substrate is provided, and a dielectric layer is formed on the substrate. Subsequently, at least one first opening is formed in the dielectric layer, and the substrate exposed by the first opening is partially removed to form at least one via opening. A conductive material layer is then formed to fill the via opening and the first opening, and the conductive material layer is planarized.
