发明名称 MICROPHONE ASSEMBLY WITH UNDERFILL AGENT HAVING A LOW COEFFICIENT OF THERMAL EXPANSION
摘要 <p>A microphone assembly comprises a carrier, a silicon-based transducer, a conducting element, and an underfill agent. The carrier has a first surface holding an electrical contact element. The silicon-based transducer comprises a displaceable diaphragm and an electrical contact element. The transducer is arranged at a distance above the first surface of the carrier. The conducting material is arranged to obtain electrical contact between the electrical contact elements of the carrier and the silicon based transducer. The underfill agent is disposed in a space between the silicon based transducer and the silicon based carrier. The underfill agent has an underfill coefficient of thermal expansion, CTE, below 40 ppm/°C.</p>
