A New Process for Manufacturing Optical Disks

9500162 比法诺 这项研究将调查一种新的制造过程中的光学编码信息光盘（如：光盘或光盘）。 目前的制造技术将进行两个主要的变化;即，（1）用坚韧陶瓷替代玻璃母盘基板，这将被用作注塑模具压模，（2）用单个离子加工步骤替代电镀，剥离，保护，抛光和冲压操作。 最重要和技术上最具挑战性的步骤是在母盘上记录CD信息的离子加工过程。 该技术将是宽束离子加工，通过掩模在单个衬底上产生数十亿个具有均匀良好质量的特征。 如果这种新的精密制造策略可以用于CD，它将有可能完成对其他微加工技术的挑战。 这项研究有可能减少一半的制造过程时间，降低制造成本和在制品库存。 此外，通过消除电镀和其他需要严格环境控制的步骤，离子束加工可以为环境友好的制造工艺提供替代选择。 随着信息技术的繁荣，光盘的大容量存储能力，这种制造过程有可能继续推动信息传播的成本。

9500162 Bifano The research will investigate a new manufacturing process for optically encoded information disks (eg: compact disks or CDs). Two major changes in the current manufacturing techniques will be undertaken; namely, (1) replacement of the glass master disk substrate by a tough ceramic, which will be used as the injection mold stamper, and (2) replacement of electroplating, peeling, protecting, polishing, and punching operations by a single ion machining step. The most important and technically challenging step is the ion machining process for recording CD information on the master disk. The technique will be broad beam ion machining though a mask to produce billions of features with uniform good quality on a single substrate. If this novel precision manufacturing strategy can be proven for CDs, it carries the potential to complete against other micromachining techniques. This research has the potential to cut manufacturing process time by half reducing both manufacturing cost and work in process inventory. Further, by eliminating electroplating and other steps requiring stringent environmental controls, ion beam machining can provide the alternate choice for an environmentally benign manufacturing process. With the boom of information technology, mass storage capabilities in CDs, this manufacturing process holds the promise for continually driving the cost of information dissemination.
