Abstract
Aspects of the disclosure provide a semiconductor device. The semiconductor device includes a first die. The first die includes a semiconductor substrate with transistors formed on a first side of the semiconductor substrate. Further, the first die includes a connection structure extending through the semiconductor substrate and conductively connecting a first conductive layer disposed on the first side of the semiconductor substrate with a second conductive layer disposed on a second side of the semiconductor substrate that is opposite to the first side of the semiconductor substrate. Further, the first die includes a shielding structure disposed in the semiconductor substrate and between the connection structure and at least a transistor. The shielding structure includes a third conductive layer and can alleviate coupling between the connection structure and the transistor.
