IBM shows working devices fabricated at 7nm node

An alliance led by IBM Research, together with New York academic institution SUNY Polytech and with Samsung and GlobalFoundries, has produced 7nm (nanometer) node test chips with functioning transistors.

Continuing semiconductor scaling down to feature sizes of 7 nm is expected to yield further gains in performance, and lower power levels, but in IBM’s words, “[its] researchers had to bypass conventional semiconductor manufacturing approaches”. The finFET-style transistors in the demonstrator were constructed with silicon-germanium (SiGe) channels, and the lithography that defined them employed Extreme Ultraviolet (EUV) technology, “at multiple levels”. [That is, the use of EUV was not reserved for definition of a single critical part of the transistor structure.]

In a bid to bring affordable solar technology to the market by 2017, IBM Research and Airlight Energy (Switzerland) have partnered to produce a solar parabolic dish that can concentrate the sun’s radiation by 2,000 times and convert 80% of it into useful energy. The system is said to be able to generate 12 kW of electrical power and 20 kW of heat under sunny conditions, and will be capable of providing both power and hot water/air conditioning to several homes.

IBM Builds World’s Biggest Brain-Chip

IBM's neurosynaptic processor puts 1 million artificial neurons and 256 million memory synapses on a single CMOS chip.

One thing IBM emphasizes about its neurosynaptic chip is that it works like the “right” brain, which means intuition and jumping to conclusions, whereas the “left” brain works more like a traditional computer: R. Colin Johnson

IBM Chip uses Graphene FETs

IBM

In a paper published in Nature Communications researchers at IBM describe how they have built a silicon-based receiver chip incorporating GFETs or Graphene Field Effect Transistors (the purple structure in the photo) into the circuit. The multi-stage receiver integrated circuit consists of 3 graphene transistors, 4 inductors, 2 capacitors, and 2 resistors.

“This is the first time that someone has shown graphene devices and circuits to perform modern wireless communication functions comparable to silicon technology,

IBM researchers store one bit of magnetic information in just 12 atoms

IBM Research – Almaden physicist Andreas Heinrich explains the industry-wide need to examine the future of storage at the atomic scale and how he and his teammates started with 1 atom and a scanning tunneling microscope and eventually succeeded in storing one bit of magnetic information reliably in 12 atoms.

IBM Thinkpad T30 Bios password reset with the Bus Pirate

Using the Bus Pirate to read the SVP supervisor power on password off an IBM T30 Thinkpad: [via]

A friend of mine recently came upon an old IBM T30 Thinkpad at an auction for $40. Bringing it home, he found that there was a power-on supervisor password. This can’t be reset by removing the battery, as the pswd is stored on an EEPROM on the motherboard….. So it came to me!

I recently purchased a Bus Pirate v3 from Seeedstudio, and decided to give it a quick test run..
