▶ Key Features CD-SEMs use a low-energy electron beam and have enhanced magnification calibration to ensure accurate and repeatable measurements. They are designed to measure features like the width, height, and sidewall angles of patterns. |
|
▶ Purpose CD-SEMs are essential for metrology in the semiconductor industry, helping to measure the critical dimensions (CDs) of patterns created during lithography and etching processes. CDs refer to the smallest feature sizes that can be reliably produced and measured on a wafer. |
|
▶ Applications These instruments are used in the manufacturing lines of electronic devices to ensure the dimensional accuracy of the various layers and features that make up a chip. They also play a crucial role in process development and control, helping to identify and correct any issues that may arise during the manufacturing process.
▶ Importance Without CD-SEMs, modern microelectronics would struggle to achieve the high level of precision and performance that is demanded by the industry. They are indispensable for ensuring the reliability and functionality of modern electronic devices. |
|
▶ Shifting Technology As lithography techniques advance and feature sizes continue to shrink, CD-SEMs are constantly evolving to meet the demands of the industry. New technologies and advancements in CD-SEM are being developed to address the challenges of measuring increasingly complex patterns |
