摘要： A method of fabricating a MOSFET device, in which a source and drain region has been formed, prior to the formation of an ion implanted channel region, has been developed. The early creation of source and drain region allows a high temperature anneal to be performed, removing damage resulting from the source and drain ion implantation procedures, however without redistribution of channel dopants. The method features creating an opening in an insulator layer, after the source and drain formation, and then forming the channel region in the semiconductor substrate, directly underlying the opening in the insulator layer. A polysilicon gate structure is next formed in the opening, resulting in self-alignment to the underlying channel region.

摘要： The present invention provides a tuning mechanism for flying pickup heads in data storage devices. The pickup device includes a coil, a pivot, a suspension, and a piezoelectric bender. The piezoelectric bender made by a bi-layer or a multi-layer piezoelectric material is formed on one end of the suspension, and proper voltages applied to the piezoelectric bender via wires enable the piezoelectric bender to undergo both neutral axis displacement and bending deflection. A pickup head is attached to the free end of the piezoelectric bender opposite to the coil, and via the piezoelectric bender, focusing and tracking motion of the pickup head can be tuned at the same time. Furthermore, since the characteristic of the piezoelectric bender is similar to bimetallic elements, the bender can undergo large bending deflection to compensate large deformation of rotating optical disks, so that the flying height of the pickup head can be tuned to maintain a constant focusing distance in reading/writing data.
摘要翻译：本发明提供一种用于在数据存储装置中飞行拾取头的调谐机构。拾取装置包括线圈，枢轴，悬架和压电弯曲机。通过双层或多层压电材料制成的压电弯曲器形成在悬架的一端，并且经由导线施加到压电弯曲机的适当电压使得压电弯曲机能够承受中性轴位移和弯曲偏转。拾音头连接到与线圈相对的压电弯曲机的自由端，并且通过压电弯曲机可以同时调节拾音头的聚焦和跟踪运动。此外，由于压电弯曲机的特性类似于双金属元件，所以弯曲机可以经受大的弯曲偏转以补偿旋转光盘的大变形，从而可以调节拾取头的飞行高度以保持恒定的聚焦距离读/写数据。
