Are NC-FETs going to make it?

Researchers at Purdue University have surveyed research towards negative capacitance field-effect transistors (NC-FETs), and published their findings. This type of transistor has a ferroelectric layer (Hf02, for example) within the gate stack, which could allow is break the 60mV/decade sub-threshold slope limit for mosfets at room temperature. “Given the potential, there is a need for ...

Bacteria extract rare earths from mining waste

Mining waste could provide a reliable supply of rare earth elements, including neodymium and dysprosium, from a type of mining waste called phosphogypsum – a product of making phosphoric acid from phosphate rock for fertilisers – according to the Idaho National Laboratory (INL). More than a billion tons if such waste is sitting idle in the ...

Semi manufacturing equipment spend expected to decline 14% this year and grow 27% next year

Spending on semiconductor manufacturing equipment is expected to decline 14% to $53 billion in 2019, but grow 27% next year  to set a new record, says SEMI. Spurred by a slowdown in the memory sector, the 2019 downturn marks the end of a three-year growth run for fab equipment spending. Over the past two years, ...
