A sensor package comprises a sensor chip () with a sensitive element () exposed to an environment of the sensor package, and contact pads () for electrically contacting the sensor package. Electrical connections () are applied between the sensor chip () and the contact pads (). A molding compound () at least partially encloses the sensor chip () and the contact pads (). A unit () consisting of the sensor chip () and optionally of a die pad () supporting the sensor chip () is arranged such that a top surface (ts) of the unit () does not protrude from a level defined by a top surface (ts) of the contact pads (), and a bottom surface (bs) of the unit () does not protrude from a level defined by a bottom surface (bs) of the contact pads ().
