摘要
A structure with an integrated circuit (IC) and a silicon condenser microphone mounted thereon includes a substrate having a first area and a second area. The IC is fabricated on the first area in order to form a conducting layer and an insulation layer. Both the conducting layer and the insulation layer further extend to the second area. The insulation layer is removed under low temperature in order to expose the conducting layer on which the silicon condenser microphone is fabricated. The silicon condenser microphone includes a first film layer, a connecting layer and a second film layer under a condition that the connecting layer connects the first and the second film layers. The first film layer and the second film layer act as two electrodes of a variable capacitance.
