Abstract (en)
[origin: WO9641412A2] A monolithic integrated circuit (1.75) is mounted in a speaker cabinet (1.71) to drive the voice coil (1.74) of the speaker (1.70). The monolithic integrated circuit may be a class D amplifier (1.10), and is at least a half-bridge or full bridge power MOSFET device. Structures and process for forming the mos switching devices (2.20) of the bridge driver circuits are disclosed. Also disclosed is the N+ buried layer (4.14) of the QVDMOS transistors (4.43) of the bridge circuits.
