Title:
SEMICONDUCTOR DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/042055
Kind Code:
A1
Abstract:
[Problem] The purpose of the present invention is to provide a semiconductor device enabling an unprecedented reduction in the impact of thermal stress, in particular on a MEMS sensor. [Solution] The present invention is characterized by comprising: a MEMS sensor (3) composed principally of silicon layered onto a printed substrate (2) (support substrate) with a first die-bonding resin (5) interposed therebetween; a first silicon substrate (11) (magnetic sensor ASIC) layered onto the MEMS sensor (3) with a second die-bonding resin (9) interposed therebetween; and a molded resin (20) serving as a sealant; the die-bonding resins (5, 9) being formed of materials softer than the molded resin (20).
