A semiconductor package includes a package substrate including a redistribution layer including first pads and second pads on an upper surface thereof and a solder mask layer having an opening exposing the first pads entirely and exposing at least portion of each of the second pads, a semiconductor chip on the upper surface of the package substrate and including connection pads electrically connected to the redistribution layer, connection bumps below the semiconductor chip and connecting the connection pads to the first pads, and a non-conductive film layer between the semiconductor chip and the package substrate, wherein the second pads are respectively disposed on both sides of the first pads at least in a first direction, and the connection bumps are spaced apart from the second pads and the solder mask layer in the first direction.

Semiconductor package

A package frame includes a plurality of unit regions disposed on one surface of the package frame, a peripheral region surrounding the unit regions on the one surface, and a wrinkled structure disposed on the one surface in the peripheral region. A first surface of the wrinkled structure extends from the one surface and is disposed at a different level than the one surface. Each of the unit regions includes a plurality of conductive pads.

Package frame and method of manufacturing semiconductor package using the same

A particulate matter (PM) sensor unit may include an exhaust line where exhaust gas passes, and a PM sensor that may be disposed at one side of the exhaust line and that generates a signal when particulate matter included in the exhaust gas passes the vicinity thereof, wherein the PM sensor may be an electrostatic induction type that generates an induction charge while the particulate matter having an electric charge passes the vicinity thereof.
