A Breakaway Technological Innovation for Space-Constrained Portable Devices
Alpha and Omega Semiconductor Limited (AOS) (Nasdaq:AOSL), a designer, developer and global supplier of a broad range of power semiconductors, todayintroduced the AOC2403 -- the industry's first Molded Chip Scale Package (MCSP) in a tiny 0.97mm x 0.97mm x 0.3mm power package. Compared to existing Chip Scale Package (CSP) solutions, MCSP reduces package height by 50% and improves the mechanical robustness of the package by protecting the encapsulated die with a layer of molding compound. The significant performance improvements of the MCSP technology make it ideal for the latest ultra-portable applications such as smart phones, tablet PCs, UltraBooks and other mobile hand-held devices.

MCSP can easily replace a standard CSP by offering the same footprint,
pin-out, and pitch, with the benefits of a more rugged and ultra-thin
package. The MCSP encapsulates AOS's low on-resistance MOSFET silicon in a Green (halogen-free) molding compound, which end result is to give it a thinner and more robust structure to solve die chipping and
placement issues associated with standard CSP products.

"The Molded Chip Scale Package offers an innovative solution to
ultra-slim designs while improving the package robustness compared to
existing CSP solutions. The innovative package, along with the low
on-resistance AOS MOSFET technology, provides designers of
ultra-portable systems with a compelling new power management
solution," said Peter Wilson, Director of Low Voltage MOSFETs at AOS.

AOC2403 is a 20V 95mOhm P-Channel MOSFET housed in a halogen-fee MCSP. The package dimensions are 0.97mm x 0.97mm x 0.3mm. The AOC2403 is the cornerstone on which additional first-class MCSP products are being developed.
