Selective Etching in Semiconductor Manufacturing
Etching is a fundamental process in semiconductor manufacturing, playing a critical role in chip fabrication. Traditionally, etching intentionally removes and deposits material to create structures on a silicon wafer. The process begins with a substrate, typically covered with an oxide layer, followed by the application of a photoresist. This setup undergoes lithography, where light exposure alters the photoresist, allowing selective removal of exposed areas to form precise patterns. These patterns guide the etching process, enabling the construction of intricate structures within a chip. This creates a harsh environment for sensors.
With the move to 3 nanometer node and below, Gate-All-Around (GAA) structures mark a significant evolution in semiconductor design from FinFET, requiring etching processes that can move beyond traditional straight-line etching to accommodate complex 3D structures. This demands higher precision and control, as manufacturers must etch both vertically and laterally to achieve desired configurations.
Selective etching involves tailoring the etching process to target specific materials while preserving others, enhancing the ability to create complex device structures with high accuracy. Selectivity is crucial for optimizing GAA chip design and ensuring uniformity and quality in the final product. At smaller scales, precision becomes paramount, as even minor deviations can have a substantial impact on device performance and quality. The intricate structures required for advanced chips demand etching techniques that can navigate multi-directional challenges, ensuring that materials are removed and deposited with exacting accuracy.
One of the primary challenges faced by semiconductor manufacturers is controlling etch rates and selectivity to achieve the desired device configurations. This must be meticulously managed to ensure the etching process aligns with the design specifications, maintaining the integrity and functionality of the chip.
INFICON’s expertise in sensor technologies and real-time gas analysis provides valuable insights, helping to refine etching processes to meet the demands of next-generation semiconductor devices.
