KLA-Tencor Introduces Additions To Sensarray™ Portfolio Of Semiconductor In-Situ Process Monitoring Solutions

MILPITAS, Calif., December 5, 2011—KLA-Tencor Corporation (NASDAQ: KLAC), the world’s leading supplier of process control and yield management solutions for the semiconductor and related industries, today introduced new additions to its SensArray portfolio of advanced wireless temperature monitoring wafers. The portfolio implements time-based, in-situ temperature monitoring to capture the effect of the process environment on production wafers, which helps integrated circuit (IC) manufacturers improve their capital equipment ROI.

Developed through collaboration with leading IC manufacturers and original equipment manufacturers (OEMs), the EtchTemp™-SE (ET-SE), ScannerTemp™ and WetTemp™-LP products enable customers to monitor temperature information across the entire wafer surface under real process conditions.  Advanced semiconductor manufacturing processes have greater sensitivity to temperature, and, consequently, monitoring temperature variation has become a more critical component of semiconductor production.

Process and equipment engineers utilize SensArray thermal information in several ways:

  • Wafer surface temperature monitoring is an indicator of manufacturing equipment performance. This information helps IC manufacturers ensure equipment health, thus enabling them to increase equipment uptime and reduce tool maintenance costs and cost of ownership.
  • Temperature variation between multiple equipment sets is a critical parameter in the qualification of tools, thus enabling faster production ramps.
  • Tracking temperature variation data enables faster root cause analysis of process excursions and detects trends that indicate possible future excursions. 

“KLA-Tencor’s SensArray products enable customers to significantly improve uptime of critical manufacturing equipment and improve process uniformity,” stated Dr. Lena Nicolaides, vice president and general manager of the SensArray-VLSI Division of KLA-Tencor’s Growth and Emerging Markets (GEM) Group. “Today customers are investing $4 billion or more to start a 32nm fab; implementing tools like KLA-Tencor’s wireless temperature monitoring products allow IC manufacturers to improve their return on this investment by enabling a faster production ramp and more effective use of capital.”

Released Products:

  • EtchTemp-SE (ET-SE)

Complementary to the industry-leading EtchTemp product, ET-SE delivers temperature wafer monitoring during silicon etch processes, providing temperature measurements with a higher signal-to-noise ratio than alternative methods.  By characterizing thermal conditions that closely represent product wafer conditions, ET-SE assists in matching front-end-of-line etch chambers and qualifying electrostatic chucks.

  • ScannerTemp

ScannerTemp allows highly accurate temperature monitoring of dry and immersion lithography systems, whose overlay performance is highly sensitive to thermal variation. With a flat, standard-thickness wafer format, it offers a sensor-to-sensor range of 0.03 degrees C in a 20-24 degrees C operating range — enabling temperature monitoring not previously available.

  •  WetTemp-LP

While prior-generation wet clean systems were compatible with SensArray SensorWafers™ thicker than standard product wafers, many new wet clean systems used in IC manufacturing require monitor wafers of standard thickness. The new WetTemp-LP is designed to be compatible with both single wafer and batch wet clean systems that require this standard-thickness wafer form factor. Integrating multiple temperature sensors, the WetTemp-LP provides rich spatial data to allow users to improve productivity and matching of wet clean systems.

KLA-Tencor also introduced BaseStation 300Z, a storage solution featuring a smart Front Opening Universal Pod (FOUP). This provides customers a clean and convenient environment for storage, charging and data transfer of the EtchTemp (dielectric etch), EtchTemp-SE (silicon etch), ScannerTemp and WetTemp-LP wafers.

KLA-Tencor’s broad portfolio of SensArray products are currently in use by IC manufacturers throughout the world, and the new product suite is immediately available.
