Preventing Loss of Memory

Hard disk drives (HDDs) use magnetic storage technology. Until recently the areal density of HDDs exceeded solid state devices. While the areal density gap is closing, the cost per gigabyte of storage is still far cheaper for HDDs. Therefore, HDDs are still the dominant storage device for data centres. HDDs are manufactured using similar processes to those found in the semiconductor industry.

Impedans offer a range of products suitable for monitoring your HDD plasma processing equipment. We have products suited for research and development work such as process development or new tool design. We also have products for live monitoring of process tools in the fab during production.
