Abstract:
A pressure sensor, comprising:a semiconductor chip having a pressure-insensitive area, a pressure-sensitive area for receiving an external pressure, and a plurality of contact areas configured on said pressure-insensitive area; a hollow housing having a housing interior, a housing base on which said semiconductor chip is configured, a housing wall surrounding said semiconductor chip, and a plurality of flat conductors each having an internal section projecting from said housing wall into said housing interior and an external section projecting from said housing wall away from said housing interior; a plurality of connecting elements, each one of said plurality of connecting elements electrically connecting one of said plurality of contact areas to said internal section of a respective one of said plurality of flat conductors; a first plastic compound covering said plurality of connecting elements, said internal section of each one of said plurality of plurality of flat conductors, and said plurality of contact areas; and a second plastic compound at least partly covering said pressure-sensitive area of said semiconductor chip; said first plastic compound undergoing less deformation than said second plastic compound when under a given pressure loading.
