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

Patent number: 7224070Abstract: The present invention provides methods and apparatus related to preventing adhesive contamination of the electrical contacts of a semiconductor device in a stacked semiconductor device package. The methods and apparatus include providing a first semiconductor device with an adhesive flow control dam located on an upper surface thereof. The dam is positioned between electrical contacts and a substrate attach site on the upper surface of the first semiconductor device. The dam is rendered of a sufficient height and shape to block applied adhesive from flowing over the electrical contacts of the first semiconductor device when a second substrate is mounted onto the upper surface of the first semiconductor device. The semiconductor device package may be encapsulated with the dam in place or with the dam removed. The adhesive flow control dam thus protects the electrical contacts of the first semiconductor device from contamination by excess adhesive, which can result in unusable electrical contacts.Type: GrantFiled: May 24, 2004Date of Patent: May 29, 2007Assignee: Micron Technology, Inc.Inventor: Jicheng Yang
