FEATURES

Transistors


Threshold voltage tuning for 10nm and beyond CMOS integration

A novel metal gate integration scheme to achieve precise threshold voltage (VT) control for multiple VTs is described.


Business


Outlook: Healthy equipment spending into 2015

The general consensus for the semiconductor industry is for this year’s positive trend to continue into 2015 as both revenue growth and unit shipment growth are expected to be in the mid- to high- single digit range.


Wafers


Managing oxide growth on in-process storage wafers for cost and yield impact

A system is described that mitigates unintended oxide growth for bare wafers while in-process storage and potentially post process at tools using nitrogen purge.


Testing


The mystery of reed relays: Understanding specifications

Specifications of reed relays, which are used for current switching in ATE and other applications are explained, including carry current, lifetime, minimum switch capacity, hot switching, operating speed and thermoelectric switching.


NEWS


For electronics beyond silicon, a new contender emerges

Silicon has few serious competitors as the material of choice in the electronics industry. Yet transistors, the switchable valves that control the flow of electrons in a circuit, cannot simply keep shrinking to meet the needs of powerful, compact devices; physical limitations like energy consumption and heat dissipation are too significant.



Rudolph introduces new acoustic metrology and defect inspection technology

Rudolph Technologies has introduced its new SONUS Technology for measuring thick films and film stacks used in copper pillar bumps and for detecting defects, such as voids, in through silicon vias (TSVs).



Sapphire display covers featured in Apple smart watches but not in iPhone 6

The long wait is finally over. From a sapphire industry standpoint, Apple killed the suspense within the first 10 minutes by announcing that its new 4.7” and 5.5” iPhone 6 and iPhone 6 plus will both feature a traditional ion-exchange strengthened glass display cover.



Fairchild Semiconductor to close two facilities, cutting 15% of workforce

Fairchild Semiconductor, a supplier of high performance power and mobile products, today announced it will eliminate its internal five-inch and significantly reduce six-inch wafer fabrication lines.
