摘要： A plurality of N-doped strip portions are formed alternating with a plurality of P-doped regions. When a voltage is applied to the N-doped strip portions, a capacitance is created between the N-doped strip portions and the P-doped strip portions. A capacitance is also created between the N-doped strip portions and the underlying epitaxial silicon layer. A larger interface area between N-doped and P-doped regions generally increases the capacitance. By providing the N-doped strip portions, as opposed to a continuous N-doped region, the combined interface area between the N-doped strip portions and the underlying epitaxial silicon layer is reduced. However, more interface area is provided between the N-doped strip portions and the P-doped strip portions. A circuit simulation indicates that junction capacitance per unit peripheral length is 0.41 fF/μm, while the junction capacitance per unit area is 0.19 fF/μmˆ2. Junction capacitance per unit peripheral length thus scales faster than junction capacitance per unit area.

摘要翻译： 多个N掺杂条带部分与多个P掺杂区域交替地形成。 当向N掺杂条带部分施加电压时，在N掺杂条带部分和P掺杂条带部分之间产生电容。 在N掺杂条带部分和下面的外延硅层之间也产生电容。 N掺杂和P掺杂区域之间的较大接口面积通常增加电容。 通过提供N掺杂条带部分，与连续的N掺杂区域相反，N掺杂条带部分和下面的外延硅层之间的组合界面面积减小。 然而，在N掺杂条带部分和P掺杂条带部分之间提供更多的界面面积。 电路仿真表明，每单位周长的结电容为0.41 fF / mum，而单位面积的结电容为0.19 fF / mum2。 每单位外围长度的结电容因此比单位面积的结电容快。

摘要： A movable wrenching tool comprises a bend shaft and a long shaft connected to the bend shaft. The bend shaft includes a first working portion extending in a first direction, a short shaft portion extending in a second direction, and a rotating portion connected to the short shaft portion. The rotating portion comprises first and second side walls extending in the second direction and being provided in parallel with each other. A position limiting notch is formed between the first and second side walls. In this case, the first direction and the second direction are different from each other. The long shaft comprises a projecting portion butted against the rotating portion, such that the projecting portion of the long shaft is inserted into the position limiting notch of the rotating portion, so as to enable the rotation of the long shaft with respect to the bend shaft.

摘要： A method and system to enable power measurements of a system-on-chip in various modes. In one embodiment of the invention, the system-on-chip has full controllability of its logic and circuitry to facilitate configuration of the system-on-chip into a desired mode of operation. This allows hooks or interfaces to access the system-on-chip externally for measurements. For example, in one embodiment of the invention, the hooks in the system-on-chip allow a backend tester to configure the system-on-chip into various modes easily to perform power consumption measurements of one or more individual components of the system-on-chip. The power consumption measurement of the individual components in the system-on-chip can be performed faster and can be more accurate. In addition, the overall yield of the SOC can be increased as it is easier to detect failure parts.
