YA-AHS (Anchor Hotspot Solution)
YA-AHS (Anchor Hotspot Solution) provides a complete application for reviewing and analyzing the results from inspection and review tools. It provides a feature-rich graphical user-interface with charting, visualization, and drill-down capabilities. Taken together, these capabilities provide a flexible tool for data analysis that produces actionable information.
Because data analysis often begins with a search for common features, pattern grouping functions are a core component of YA-AHS. The rich grouping engines of Result Explorer are included and integrated with the GUI — including both signature extraction and signature grouping.
In addition, YA-AHS can import and analyze CD-SEM data from Hitachi and NGR tools.

Technical Requirements
The minimum system requirements are listed below:
Memory and hard drive requirements can vary substantially from customer to customer. Customers who expect to store large quantities of images on the server should allocate appropriate hard drive capacity. Customers who expect to process large numbers of images should allocate additional physical memory. Anchor Semiconductor will help each customer with the appropriate sizing of their hardware.
- Linux 2.6 or later, 64-bit, x86 based processor.
- 16 or more physical cores.
- 128 GB or more physical memory.
- 2 TB or more available hard drive capacity.
