Low Frequency Noise Measurement System


Primarius 9812DX is an enhanced version of the industry's de-facto standard flicker noise (1/f noise) measurement systems 9812D and 9812B. 9812DX sets new records in measurement speed, system resolution and coverage of different types of measurement requirements for flicker noise and random telegraph noise or signaling (RTN or RTS). Flicker noise is the dominant noise for deep sub-micron and nanometer CMOS, bipolar junction transistor (BJT), field effect transistor (FET) and heterojunction bipolar transistor (HBT) devices.


9812DX includes an order of magnitude improvement in measurement resolution compared with the legacy systems, and higher voltage tolerance of up to 200V. The 9812DX system provides extended capability to cover extreme conditions such as diode dark current noise and is the only system in the market that accommodates a complete range of measurement conditions for both high and low impedance devices, ranging from 10Ω to 10MΩ.


To meet the challenge of explosive growth requirements for low frequency noise test in advanced technology nodes, especially FinFET technology, 9812DX delivers a significant and innovative improvement in hardware and software design. With a typical noise measurement speed of 20 sec/ bias, 9812DX sets a new high-speed record. The 9812DX can be used in conjunction with the Primarius semiconductor parameter testing system FS-Pro, providing a parallel testing framework solution that significantly improves testing efficiency and throughput. 

The 9812DX has been adopted by many foundries following 9812B/D and has become the new golden tool for low frequency noise testing. It is widely used for development of the most advanced semiconductor process technology nodes, from 14nm and 10nm to 7nm and 5nm.
