Face-to-face for 20MByte chip card security control
Infineon Technologies is using an innovative "chip-sandwich" technique that involves face-to-face interconnection to design chip card ICs for use in mobile communications. One aim is to offer more than 100 times the memory capacity of today's chip cards, while just doubling the chip's area. The new chip card ICs will not only deliver significant performance boosts, the company says, but will enable new applications for mobile phones and smart cards.
Infineon claims the world's first chip card security controller using the innovative face-to-face technology, offering 1MByte of memory capacity, manufactured in a 130nm process technology.
