For a mono and multi silicon crystalline defect testing lab or any metrology lab, it is critical to provide 1) reliable results and 2) consistent results. Without these two components, process engineer (silicon crystal grower engineer, solar engineer and Semiconductor engineer) are not able to move forward to produce a high-yield efficiency.
It is an advantage to both silicon crystal growth company and device maker company to establish a solid test lab, to know 1-what silicon defect matters and 2-to understand the process interaction between silicon and the device.
