quasicrystals, semiconductors, and other materials. It also examines effects of pressure on diffusion. Symposia AA and FF focus on epitaxy, the first examining metallic systems and the second examining Si-based heterostructures. Growth of metals on metals is an important problem to a number of industries, such as catalysis and magnetic recording. The process is complicated because film growth is a nonequilibrium phenomenon, so kinetic models must be used as well as thermodynamic models to describe film growth and evolution. Another approach to microstructural evolution will be given in Symposium BB, focusing on computational and mathematical models. The continued miniaturization of device circuits has led to various challenges for processing semiconductor devices, leading to new fields of study. Symposium I, Advanced Interconnects and Contact Materials and Processes for Future ICs, begins with a full day of invited presentations covering interconnect frontiers, for example looking at interconnection limits on 21st century gigascale integration, copper interconnect technology, scaling issues, and optical interconnects. Likewise, development is moving quickly in the field of Low-Dielectric Constant Materials and Applications in Microelectronics II, Symposium E. A practical technique that quickly gained use throughout the semiconductor industry is chemical-mechanical polishing, which is covered in Symposium Q. Rapid thermal and laser processing also have an important place in materials processing, as represented in Symposia W and Y. Symposium Y, Advances in Laser Ablation of Materials, will hold a panel discussion on Tuesday afternoon looking back 10 years to the beginning of pulsed laser deposition of high-temperature superconductors, and then looking to future directions.
The 1998 MRS Spring Meeting program covers a broad spectrum of materials research, with a strong component on electronic materials and devices. The 32 technical symposia, some with joint sessions, follow technological developments from fundamentals such as crystal growth, epitaxy, and defect behavior through processing of semiconductors, to metallization, packaging, and reliability. The meeting, to be held at the San Francisco Marriott April 13-17, will address both experimental and theoretical aspects of materials. The meeting is rounded out with sessions on characterization, biomaterials, magnetic and optical materials, structural porous materials, hybrids, and other topics. Over 2,400 poster and oral presentations are planned, 400 more than scheduled for the 1997 Spring Meeting. Defects and impurities are important players in semiconductor performance. Symposium D specifically focuses on Defect and Impurity Engineered Semiconductors and Devices. Symposium EE, Silicon
