MEMORY

Digging Deep into High Aspect Ratio Process Control for Memory Technology

Data is an integral part of our lives. Contrary to the past, where files had to be removed periodically to free up storage space, we now assume that our data will never be deleted. Why risk deleting the wrong file? Just keep them! This new approach consumes a lot of memory, and intensifies the demand for storage. Two of the main workhorses of the memory segment are NAND flash and DRAM. DRAM is dynamic, volatile and very fast, making it well suited for short term system memory. Conversely, NAND flash is non-volatile, which means it has good retention and can function well for long term low-cost storage. Higher speed, higher density and lower bit cost have been the main goals for both of these memory types as demand continues to increase.

PRODUCT SPOTLIGHT: SensArray

KLA-Tencor's SensArray wafers provide a unique way -- not available through other means -- to monitor the effect of the process environment on semiconductor production wafers. Measurements are used by chipmakers and process equipment manufacturers to optimize and control their processes and process tools.

Process and equipment engineers alike utilize SensArray wafers throughout the fab for thermal information as an indicator of manufacturing equipment performance. With more advanced semiconductor manufacturing technologies -- such as smaller design rules, new materials, and new structures -- temperature control is becoming more critical.

Introducing the Surfscan SP3 450

The Surfscan® SP3 450 is the first of KLA-Tencor’s process control systems capable of handling and inspecting 450mm wafers. As a new configuration of the market-leading Surfscan SP3 platform, these fully-automated unpatterned wafer inspection systems feature unique deep ultra-violet (DUV) sensitivity and unique high-resolution SURFmonitorTM surface quality characterization to support sub-20nm node requirements. The Surfscan SP3 450 enables manufacturing process control for 450mm polished silicon and epitaxial silicon substrates and also delivers critical capability for manufacturers of 450mm process equipment, such as wet clean tools, CMP pads, slurries and polishers, film deposition tools and annealing systems.
