  • Semiconductor device burn-in stress method and system
    Patent number: 9176184
    Abstract: Burn-in (BI) stress using stress patterns with pin-specific power characteristics. A control device for each conductive pathway from BI board (BIB) contacts to device under test (DUT) connectors/contacts can adjust power delivered to a respective connector/contact responsive to a controller. The control devices can be included in the BIB or an interposer (IP) can be used with existing equipment. Each control device can include a regulator, such as a latchable array of field effect transistors that can regulate power delivered to a respective package connector.
