Hyunsung TNC’s Circular Target Laser Ablation (CTLA) technology is an innovative deposition method that fundamentally differs from conventional techniques such as PLD (Pulsed Laser Deposition) and sputtering.
Traditional approaches rely on pre-synthesized compound targets that are deposited onto a substrate, making material synthesis and film formation two separate steps with limited control over fine composition tuning.
In contrast, CTLA arranges individual elemental targets in a circular configuration, and utilizes laser beams that are precisely programmed and tuned for each element’s specific characteristics—such as wavelength, pulse duration, and energy.This allows the system to synthesize the superconducting oxide compound in real time and deposit it directly onto the substrate in a single-step process.
The result is a dramatic improvement in stoichiometric accuracy, film uniformity, and process reproducibility, positioning CTLA as a next-generation manufacturing platform for room-temperature superconducting materials.
