Semiconductor sensor device with sensor chip and method for producing the same

A semiconductor sensor device, comprising:

• a sensor chip including a sensor region and contact areas disposed on an upper side of the sensor chip;
• a cavity housing comprising side walls, a housing bottom and a cavity disposed between the side walls and housing bottom;
• a leadframe comprising external contacts disposed outside the cavity of the cavity housing, wherein the external contacts comprise external flat conductors arranged on an underside of the housing bottom, the leadframe further comprising contact pads disposed on an upper side of the housing bottom facing the cavity, the contact pads being electrically connected to the external contacts via through contacts, wherein the external flat conductors comprise external contact areas that undergo a transition from the underside of the housing bottom to the through contacts that extend through the housing bottom and that undergo a further transition from the through contacts to the contact pads;
• elastic flip-chip contacts;
• and
• a rubber-elastic plastic composition disposed within the cavity, wherein the sensor chip is at least partly embedded in the rubber-elastic plastic composition, the sensor region is arranged facing the housing bottom, the contact areas are electrically connected to the elastic flip-chip contacts, the elastic flip-chip contacts are electrically connected to the contact pads, and the rubber-elastic plastic composition includes a section that is disposed over the sensor region and has a thickness that is defined between the upper side of the sensor chip and the upper side of the housing bottom.
