ABSTRACTThe successful methods for laser ablation and deposition of epitaxial thin films of metal oxides, especially the high-temperature superconductors (HTSC), have been adapted to pulsed laser deposition (PLD) of the narrow-band compound semiconductor HgCdTe, and the wide-band semiconductor β-SiC. Useful film quality is readily obtained in both cases: the HgCdTe films on CdTe wafers function in IR photodetection and the 3-SiC is epitaxial on both Si (100) and (111) wafers.

Pulsed laser deposition (PLD) exhibits unique advantages for the preparation of functional thin films which are widely used in microelectronics, photoelectrons, integrate circuits, superconductors and biomedical fields. The principle of and the characteristics of PLD are introduced, its applications in ferroelectrics, high-temperature superconductors, diamond-like and superlattices. The future application trend is reviewed.

Despite the discovery of the laser a few decades ago, the potential for pulsed laser deposition (PLD) of thin films has remained unexploited. Despite the sustained pioneering work at Rockwell in laser deposition, it took the development of high-temperature superconductors to fully realize the technique's potential. Early work on PLD of high-temperature superconductors demonstrated for the first time that the composition of rather complex multi-elementary materials can be reproduced in the deposited film under appropriate conditions of laser energy density and deposition angle. These features made PLD unique; and once the recipe for making in-situ crystalline films of proper stoichiometry was known, the technique's popularity was significantly enhanced in the research community.The features of laser deposition that make the process so unique, and that are discussed throughout this issue, are recapped below:1. Rather complex multi-elementary materials can be deposited well if a single-phase, homogeneous target can be fabricated. The complexity of the deposition process is translated to the relatively easier process of fabricating a high-quality target.2. The chamber pressure, target-substrate distance, target orientation with respect to the laser beam, etc. are significantly de-coupled, enabling significant freedom in deposition system design. The target is decoupled from the substrate in the sense that a small target can be used to deposit film over a fairly large area substrate with the appropriate scanning schemes.3. The efficiency of the target use is superior compared to any other technique since a predominant amount of the evaporated material is forward directed and can be collected with a high degree of efficiency. For example, in a production environment, more than 100 YBCO films (ranging 3,000-4,000 Å thick) on 1 × 1 cm2 substrates have been fabricated from a 0.25-inch-thick one-inch target with a majority of the target still left over. The cost of raw materials in a production environment may become significant, and for toxic elements particularly there is a further advantage in minimizing the spread of contaminants.
