The invention provides a
pressure sensor, which comprises a lining board, a glass foundation
bed, a
chip, a
silicon substrate, a pressing groove, a
silicon elastic film, electrodes, pins and glass
slurry, wherein the glass substrate is arranged on the lining board; the
chip is embedded into the upper wall of the glass foundation
bed; the
silicon substrate is arranged on the top of the glass foundation
bed; the pressing groove is arranged on the upper wall surface of the silicon substrate, and the pressing groove is sunken to the bottom of the silicon substrate; the silicon elastic film is attached to the inner wall of the pressing groove; the electrodes and the
chip are electrically connected, and the electrodes are embedded into the upper wall surface of the glass substrate; the pins andthe electrodes are connected, and the pins penetrate through the foundation bed and the lining board; and the glass
slurry is embedded into the glass foundation bed, and the glass
slurry covers the outer sides of the electrodes and the pins. Pin holes are processed on the corresponding positions of the glass foundation bed and the electrodes, the pins and the electrodes are connected, the pins penetrate through the glass foundation bed and the lining board, and therefore, a required space for the horizontal direction of the chip is reduced.
