Web3.1 CDSEM CDSEM is typically used in the semiconductor manufacturing process to measure lateral dimensions on the wafer [6]. To quantify LCDU, an image of a via array is captured by CDSEM, then the diameter is determined for each via individually and the standard deviation calculated. Depending on the amount of vias within one image, several … WebNew Model CD-SEM for 45-nm Devices and Beyond 42 and it is important to develop a solution that combines precise high-stability length measurements and application functions. The CG4000 is a CD-SEM that enables anyone to perform precise stable length measurements in processes with a hp of 45 nm or beyond. WebA Critical Dimension SEM (CD-SEM: Critical Dimension Scanning Electron Microscope) is a dedicated system for measuring the dimensions of the fine patterns formed on a semiconductor wafer.
