High-Resolution inspection for bonding voids in Solid-Liquid-Interdiffusion (SLID) bond interfaces by Acoustic GHz-Microscopy

Activity: Talk or presentation typesConference presentation


Solid-Liquid-Interdiffusion (SLID) bonding is promising for formation of:
-Bond frames and hermetic seals for MEMS
-Micro-connects for 3D integration in microelectronics
-Die attach for power semiconductors
Major advantages:
-Formation of high-temperature stable bonds processed at low temperatures
High strength
GHz-SAM allows defect detection down to few 100 nm diameter through a few µm of remnant Si
Application to bond quality analysis for process development studied with respect to small voids
