    • A temperature compensated self-refresh circuit maintains a stable current characteristic by maintaining a predetermined self-refresh cycle to cope with a process skew and a voltage change in a low power consumption memory product and by changing the self-refresh cycle only depending on temperature change. The temperature compensated self-refresh circuit is provided with a reference voltage generating unit adapted and configured to use an internal power voltage of a Widlar type so as to reduce a process skew and to have NMOS transistors with a LVT (Low Voltage Transistor) structure so as to have the same voltage as that of a temperature sense unit, thereby maintaining a predetermined cycle of an oscillating signal coping with the process skew.
    • 温度补偿自刷新电路通过保持预定的自刷新周期来保持稳定的电流特性,以应对低功耗存储器产品中的工艺偏差和电压变化,并且仅通过根据温度变化改变自刷新周期 。 温度补偿自刷新电路设置有参考电压产生单元,其被配置为使用Widlar类型的内部电源电压,以便减少处理偏斜并且具有LVT(低电压晶体管)结构的NMOS晶体管,因此 具有与温度检测单元相同的电压,从而保持响应于处理偏斜的振荡信号的预定周期。

    • A method and apparatus for etchback profile control. The method includes performing a first etch through a first dielectric layer to form a first via and a second dielectric layer, filling the first via with a BARC material to form a first BARC layer, and performing a second etch on the first BARC layer to form a second BARC layer. The second etch has a first etch rate in a first peripheral region of the second BARC layer and a second etch rate in a first central region of the second BARC layer. The first peripheral region is located around a sidewall of the first via, and the first central region is located around a center of the first via. The first etch rate is larger than the second etch rate, and the first peripheral region is located higher than the first central region. A first top surface of the second BARC layer has substantially a first convex shape. Additionally, the method includes performing a third etch through a second dielectric layer to form a trench and a third BARC layer. The trench has a trench bottom surface, which is substantially free from any spike around a side surface of the third BARC layer. A second top surface of the third BARC layer has substantially a second convex shape. Moreover, the method includes removing the third BARC layer to form a second via.
    • 一种用于回蚀型材控制的方法和装置。 该方法包括通过第一电介质层进行第一蚀刻以形成第一通孔和第二电介质层,用BARC材料填充第一通孔以形成第一BARC层,以及在第一BARC层上执行第二蚀刻以形成 第二个BARC层。 第二蚀刻在第二BARC层的第一外围区域具有第一蚀刻速率,在第二BARC层的第一中心区域具有第二蚀刻速率。 第一周边区域位于第一通孔的侧壁周围,第一中心区域位于第一通孔的中心附近。 第一蚀刻速率大于第二蚀刻速率,并且第一周边区域位于高于第一中心区域。 第二BARC层的第一顶表面具有基本上第一凸形形状。 另外,该方法包括通过第二介电层执行第三蚀刻以形成沟槽和第三BARC层。 沟槽具有沟槽底表面,其基本上没有围绕第三BARC层的侧表面的任何尖峰。 第三BARC层的第二顶表面具有基本上第二凸形形状。 此外,该方法包括移除第三BARC层以形成第二通孔。

    • A storage device system includes a storage control device with a file system for execution of data I/O processing relative to a storage device according to a data I/O request by means of file identifier assignment as sent from a host computer. A computer is connected between the host and the storage control device with a per-host accessible file storage region being reserved on the storage region of a storage device that the storage control device owns. The computer stores in a database a first correspondence established between a first ID which is added on a per-host basis and a file identifier which is added to a file that is stored in the file storage region and then compares to the first correspondence a correspondence between a first ID and a file identifier which is included in the data I/O request received from the host to thereby determine whether the received request is acceptable.
