    • A method and structure implant a first-type impurity within a substrate to form a channel region within the substrate adjacent a top surface of the substrate; form a gate stack on the top surface of the substrate above the channel region; and implant a second-type impurity within the substrate to form source and drain regions within the substrate adjacent the top surface. The channel region is positioned between the source and drain regions. The second-type impurity has an opposite polarity with respect to the first-type impurity. The method and structure implant a greater concentration of the first-type impurity, relative to a concentration of the first-type impurity within the channel region, to form a primary body doping region within the substrate below (relative to the top surface) the channel region; and to form secondary body doping regions within the substrate below (relative to the top surface) the source and drain regions.

    • A method and apparatus for detecting a defective disk for a hard disk drive. The method includes placing a disk into a tester so that a first side of the disk is adjacent to a first head of the tester and a second side of the disk is adjacent to a second head. First data is read from the first side of the disk, and second data is read from the second side of the disk. The disk is then flipped so that the second side is adjacent to the first head and the first side is adjacent to the second head. Third data is read from the first side. Fourth data is read from the second side. A first area between a curve generated from the first data and a curve generated from the third data is calculated. Likewise, a second area is calculated between a curve generated from the second data and a curve generated from the fourth data. An average of the first and second areas is then calculated and used to detect a defective disk.

    • A vertical pass transistor used in a DRAM cell for maintaining a low total leakage current and providing adequate drive current is described together with a method of fabricating such a device. The transistor gate is engineered in lieu of the channel. The vertical pass transistor for the DRAM cell incorporates two gate materials having different work functions. The gate material near the storage node is n-type doped polysilicon. The gate material near the bit line diffusion is made of silicide or metal having a higher work function than the n-polysilicon. The novel device structure shows several advantages: the channel doping is reduced while maintaining a high Vt and a low sub-threshold leakage current; the carrier mobility improves with the reduced channel doping; the body effect of the device is reduced which improves the write back current; and the sub-threshold swing is reduced because of the low channel doping.
    • 在DRAM单元中使用的用于保持低总漏电流并提供足够的驱动电流的垂直传输晶体管与制造这种器件的方法一起被描述。 晶体管栅极被设计代替通道。 用于DRAM单元的垂直传输晶体管包括具有不同功函数的两个栅极材料。 存储节点附近的栅极材料为n型掺杂多晶硅。 位线扩散附近的栅极材料由具有比n-多晶硅更高的功函数的硅化物或金属制成。 该新颖的器件结构显示出几个优点:沟道掺杂减少,同时保持高Vt和低的亚阈值漏电流; 载流子迁移率随着沟道掺杂的降低而提高; 减少了器件的体效,提高了回写电流; 并且由于低通道掺杂,子阈值摆幅减小。

    • Thermal pole tip protrusion is caused by materials in and around head slider expanding during write operations till they protrude, leading to contact with the rotating disk surface, altering the flying height and often wearing down part of the disk surface. While well known that read-write heads expand during writing, the inventors who recognized this situation's significance, particularly as flying height decreases and data rates increase, both required for high areal density disk drives. The inventors realized that they could detect the problem at the spin stand level by testing head gimbal assemblies to reliably, and inexpensively, predict the tendency for thermal pole tip protrusion. This leads to selection of head gimbal assemblies, which do not have the thermal pole tip protrusion tendency. The selected head gimbal assemblies have better reliability, as do actuators and disk drives made with the selected head gimbal assemblies.
    • 热敏头尖突起由写入操作期间头部滑块内和周围的材料引起,直到它们突出,导致与旋转盘表面接触,改变飞行高度并经常磨损盘表面的一部分。 虽然众所周知,读写头在写入期间扩展,但是认识到这种情况的重要性的发明人,特别是当高密度磁盘驱动器都需要飞行高度降低和数据速率增加时。 本发明人意识到,它们可以通过测试头万向架组件可靠且廉价地预测热极尖端突起的趋势来检测旋转台水平的问题。 这导致了不具有热极尖突起倾向的头万向节组件的选择。 所选择的头万向架组件具有更好的可靠性,与使用所选择的头万向架组件制造的致动器和磁盘驱动器一样。
