Single Wafer Casting

Converting silicon to wafers by a process of individually casting wafers has great cost advantages over conventional ingot casting methods. The Molded Wafer process demonstrates good silicon utilization, low processing cost, and offers efficiencies approaching that of conventional cast multicrystalline wafers. The ability to alter the casting mold offers freedom in wafer shape and presents the means to incorporate features such as metallization through holes at no added cost. These benefits make single wafer casting an economically viable option in times of silicon shortages and highly competitive product pricing.
