摘要:
A system and method for a micro-electrical-mechanical system (MEMS) device including a substrate and a free-standing and suspended electroplated metal MEMS structure formed on the substrate. The free-standing and suspended electroplated metal MEMS structure includes a metal mechanical element mechanically coupled to the substrate and a seed layer mechanically coupled to and in electrical communication with the mechanical element, the seed layer comprising at least one of a refractory metal and a refractory metal alloy, wherein a thickness of the mechanical element is substantially greater than a thickness of the seed layer such that the mechanical and electrical properties of the free-standing and suspended electroplated metal MEMS structure are defined by the material properties of the mechanical element.
摘要:
A MEMS capacitive transducer with increased robustness and resilience to acoustic shock. The transducer structure includes a flexible membrane supported between a first volume and a second volume, and at least one variable vent structure in communication with at least one of the first and second volumes. The variable vent structure includes at least one moveable portion which is moveable in response to a pressure differential across the moveable portion so as to vary the size of a flow path through the vent structure. The variable vent may be formed through the membrane and the moveable portion may be a part of the membrane, defined by one or more channels, that is deflectable away from the surface of the membrane. The variable vent is preferably closed in the normal range of pressure differentials but opens at high pressure differentials to provide more rapid equalization of the air volumes above and below the membrane.

Provided is a method of manufacturing an electromechanical transducer having a reduced variation in a breakdown strength caused by a variation in flatness of an insulating layer. In the method of manufacturing the electromechanical transducer, a first insulating layer (2) is formed on a first substrate (1), a barrier wall (3) is formed by removing a part of the first insulating layer, and a second insulating layer (10) is formed on a region of the first substrate after the part of the first insulating layer has been removed. Next, a gap is formed by bonding a second substrate (18) on the barrier wall, and a vibration film (23) that is opposed to the second insulating layer via the gap is formed from the second substrate. In the forming of the barrier wall, a height on a gap side in a direction vertical to the first substrate becomes lower than a height of a center portion.
