Patent number: 9681242Abstract: A MEMS microphone system suited for harsh environments. The system uses an integrated circuit package. A first, solid metal lid covers one face of a ceramic package base that includes a cavity, forming an acoustic chamber. The base includes an aperture through the opposing face of the base for receiving audio signals into the chamber. A MEMS microphone is attached within the chamber about the aperture. A filter covers the aperture opening in the opposing face of the base to prevent contaminants from entering the acoustic chamber. A second metal lid encloses the opposing face of the base and may attach the filter to this face of the base. The lids are electrically connected with vias forming a radio frequency interference shield. The ceramic base material is thermally matched to the silicon microphone material to allow operation over an extended temperature range.Type: GrantFiled: August 21, 2014Date of Patent: June 13, 2017Assignee: INVENSENSE, INC.Inventors: Kieran P.

Patent number: 9351084Abstract: A size of a port hole in a package for a micro-electro-mechanical (MEMS) microphone can be modified to improve performance of the MEMS microphone while protecting the MEMS microphone from environmental interference. As an example, the port hole diameter is increased along a thickness of a substrate coupled to the MEMS microphone to reduce air mass loading and air flow resistance and thus, increase the resonant frequency, resonant peak, signal-to-noise ratio (SNR) and/or a range for flat frequency response of the MEMS microphone. In one aspect, the port hole can be created by mechanical and/or laser drilling. In another aspect, the port hole can be created by forming a cavity in the substrate over a drilled port hole.Type: GrantFiled: July 14, 2014Date of Patent: May 24, 2016Assignee: INVENSENSE, INC.Inventor: Jia Gao

Patent number: 8853839Abstract: A housing for integrated devices that includes an air-release mechanism is disclosed. This is achieved, in various embodiments, by forming a vent hole in a package substrate, and arranging a package lid over the package substrate. The vent hole allows air to be released from within the cavity package, thereby ensuring that the package lid remains stably affixed to the package substrate despite increased temperatures during processing. The vent hole may be sealed upon mounting the package onto a mounting substrate.Type: GrantFiled: October 4, 2012Date of Patent: October 7, 2014Assignee: Analog Devices, Inc.Inventors: Jia Gao, Jicheng Yang, Shafi Saiyed, Siu Lung Ng, Xiaojie Xue
