IBM Extends Moore's Law to the Third Dimension
This is the fifth major chip breakthrough in five months from IBM, as it leads the industry in its quest for new materials and architectures to extend Moore’s Law.
In December, IBM announced the first 45nm chips using immersion lithography and ultra-low-K interconnect dielectrics.
In January, IBM and Intel separately announced “high-k metal gate,” which substitutes a new material into a critical portion of the transistor that controls its primary on/off switching function.
In February,IBM revealed a first-of-its-kind, on-chip memory technology that features the fastest access times ever recorded in eDRAM (embedded dynamic random access memory).
Then in March, IBM unveiled a prototype optical transceiver chipset capable of reaching speeds at least eight-times faster than optical components available today.
Quantum secrets of photosynthesis revealed
The photosynthetic technique for transferring energy from one molecular system to another should make any short-list of Mother Nature’s spectacular accomplishments. If we can learn enough to emulate this process, we might be able to create artificial versions of photosynthesis that would help us effectively tap into the sun as a clean, efficient, sustainable and carbon-neutral source of energy.
