Abstract: For the development of an economical production technology of multi-crystalline silicon, an EMCC (Electro Magnetic Continuous Casting) process using a segmented Cu cold crucible was practiced. In order to enhance significantly the heating efficiency of silicon melt keeping non-contact condition during continuous melting and casting processes, the effects of Joule heating and electromagnetic pressure in molten silicon were optimized by systematically varying crucible design and configuration. Throughout the present investigation, multi-crystalline silicon ingot was successfully produced at the casting speed of above 1.5 mm/min under a non-contact condition.

Abstract: Lead-free Ba(Ti1-xZrx)O3 (BTZ) thin films were fabricated on Pt(111)/Ti/SiO2/Si(100) substrates by the chemical solution deposition (CSD) process. The microstructure of the BTZ (x = 0.00 to 0.20) thin films was improved by additional sintering process, and their crystallite sizes were increased in each composition. The dielectric constant er and piezoelectric constant d33 of the BTZ thin films depended on the crystallite size. We give a guide for further investigation to improve the characteristics of BTZ thin films.
