TDM's OCT Module: A Precision Tool for Advanced Planarization and Packaging
The Evolving Landscape of Semiconductor Manufacturing
As semiconductor technology continues its relentless march towards miniaturization and increased functionality, planarizationand advanced packaging have emerged as critical enablers. These processes demand unparalleled surface topography and thickness control precision to ensure device performance and reliability.
The Role of Planarization
Planarization is a crucial step in semiconductor manufacturing. It involves smoothing the wafer surface to facilitate subsequent processing steps like metallization, dielectric deposition, and photolithography. In advanced nodes and packaging technologies, such as 3D integration and chipset designs, achieving precise planarization becomes even more challenging.
