Abstract: A capacitive biosensor is provided. The capacitive biosensor includes: a transistor, an interconnect structure on the transistor, and a passivation layer on the interconnect structure. The interconnect structure includes a first metal structure on the transistor, a second metal structure on the first metal structure, and a third metal structure on the second metal structure. The third metal structure includes a first conductive layer, a second conductive layer, and a third conductive layer that are sequentially stacked. The passivation has an opening exposing a portion of the third metal structure. The capacitive biosensor further includes a sensing region on the interconnect structure. The sensing region includes a first sensing electrode and a second sensing electrode. The first sensing electrode is formed of the third conductive layer, and the second sensing electrode is disposed on the passivation layer.

Abstract: An electronic device is provided. The electronic device includes a redistribution structure, an electronic unit and a first conductive pad. The first conductive pad is disposed between the redistribution structure and the electronic unit. The electronic unit is electrically connected to the redistribution structure through the first conductive pad. The first conductive pad has a first coefficient of thermal expansion and a first Young's modulus. The first coefficient of thermal expansion and the first Young's modulus conform to the following formula: 0.7×(0.0069E2?1.1498E+59.661)?CTE?1.3×(0.0069E2?1.1498E+59.661), wherein CTE is the first coefficient of thermal expansion, and E is the first Young's modulus in the formula.

Abstract: A semiconductor device includes a first region and a second region, and the second region surrounds the first region. The semiconductor device includes at least one electronic unit, a redistribution structure, a plurality of first pads, and a plurality of second pads. The redistribution structure may be electrically connected to at least one electronic unit. A plurality of first pads are arranged on the redistribution structure and correspondingly to the first region. There is a first pitch between two adjacent first pads. A plurality of second pads are arranged on the redistribution structure and correspondingly to the second region. There is a second pitch between two adjacent second pads, so that the first pitch is smaller than the second pitch.

Abstract: A multi-functional lock may include a main body, a control unit, a connecting unit and a securing unit. The multi-functional lock is advantageous because the main body uses the connecting unit to control the securing unit and control unit, and a rod and a locking unit are independent components, so when the user is conducting a forcefully unlocking process, only the rod is damaged without damaging the main body and the rod can be easily replaced.
