Atomic Layer Printing (ALP) is a nanofabrication technique that allows for precise deposition of materials layer by layer at the atomic scale, enabling the creation of three-dimensional structures with unparalleled precision and control.
ALP addresses the need for ultra-precise manufacturing at the nanoscale, which is critical for advanced processor designs and the development of new medical technologies such as targeted drug delivery systems.
ALP involves alternating exposures to different gases or chemicals in a vacuum environment. Each gas or chemical reacts only with one surface of the substrate, depositing atoms or molecules in a controlled manner. This process is repeated multiple times to build up layers of material, ensuring that each layer is atomically perfect before moving on to the next.
The process requires a cleanroom environment with precise temperature control. The materials used are typically gases or reactive chemicals that can be precisely controlled in a vacuum chamber.
ALP involves multiple steps, including surface preparation, gas exposure, and reaction. Each step must be carefully controlled to ensure the desired atomic-level precision.
Field units draw low hundreds of watts; fabrication is energy-intensive due to vacuum baking, which requires significant power consumption.
