嗨，我用100mR电阻和0.1uF电容在DS21823D、MCP73843数据表的第1页上建立了示例电路。我可以从3.6V-4.2V充电3000毫安电池，不会发生错误。然而，如果我从1.2V-4.2V给这个电池充电，充电电路超时并显示出闪烁故障。我试着将电阻降低到50mR以便更快地给电池充电，但是充电单元立即显示出闪烁故障。在数据表中，建议只使用0.1uF电容器？除了改变充电电阻，我看不出还有什么需要充电更大容量的电池。请你指出我要从1页上显示的示例电路中更换一个3000毫安的电池。谢谢。

sockets are indeed depleted. But NET_PRES_SocketOpen would not return NET_PRES_INVALID_SOCKET but some

我最近购买了一个固件版本为7.05的E4406A，s / n US3903xxxx，它工作正常，没有错误的自拍，没有问题的自动对齐，并且应该正常工作。由于最新的固件是10.08，我决定升级该仪器的固件。但是，当我尝试升级时，我注意到在升级的最后，状态消息说有几个文件无法创建。即便如此，升级后屏幕上的最后一条消息是升级完成后我应重启并重新启动仪器。当我重新启动仪器时，我正在看启动屏幕，发现了一个我以前从未见过的消息。它说：vsa vsa：糟糕的价值，但继续启动。最终我听到衰减器继电器发出咔嗒声，在它开始自我测试之前它就到了空白的白色屏幕。但它没有到达那里，并在屏幕上显示以下消息：users / arcturus / .xinitrc：57内存故障固件退出，循环电源重新启动产生相同的结果。我还尝试使用安装程序中的“非功能性仪器”选项安装固件版本8.10第2版，但获得的结果与10.08固件相同。最后，我再次使用“非功能性仪器”选项恢复到7.05固件，我的E4406A恢复正常工作。有谁知道这可能导致什么？ 7.05和更高版本之间的固件是否有重大变化可能解释这种不兼容性？接下来要检查什么的想法？我有另一台E4406A我已成功升级到10.08，所以我非常有信心我知道这个程序，但是任何和所有的建议都会受到赞赏。谢谢，StanEdited：swperk于2015年2月22日上午8:22 以上来自于谷歌翻译 以下为原文I recently acquired an E4406A with firmware version 7.05, s/n US3903xxxx, and it works fine, boooting without errors, self-aligning without a problem, and working as it should. Since the latest firmware is 10.08, I decided to upgrade the firmware in this instrument. However, when I tried to upgrade, I noticed that at the very end of the upgrade, the status messages said that there were several files that it was unable to create. Even so, the final message on the screen after the upgrade was that the upgrade was complete and I should power cycle and reboot the instrument. When I restarted the instrument, I was watching the boot screen and noticed a messsage that I hadn't seen before. It said: vsa vsa: bad value but continued to boot.Eventually I heard the attenuator relays click, and it got to the blank white screen just before it would have started the self-testing. It didn't get there, though, and stopped with the following message on the screen: users/arcturus/.xinitrc: 57 memory fault Firmware exit, cycle power Restarting produced the same results. I also tried installing firmware version 8.10 Release 2 by using the "non-functional instrument" option on the installer, but got the identical results as with the 10.08 firmware. Finally, I reverted back to the 7.05 firmware, again by using the "non-functional instrument" option, and my E4406A is back to working fine. Does anyone know what might be causing this? Was there a significant change in firmware between 7.05 and the later versions that might explain this incompatibility? Any ideas of what to check next? I have another E4406A that I have sucessfully upgraded to 10.08, so I'm pretty confident that I know the procedure, but any and all suggestions would be appreciated.

半导体发展至今，无论是从结构和加工技术多方面都发生了很多的改进，如同Gordon E. Moore老大哥预测的一样，半导体器件的规格在不断的缩小，芯片的集成度也在不断提升，工艺制程从90nm、65nm、45nm、32nm、22nm、14nm、10nm、到现在的7nm（对应都是MOS管栅长），目前也有了很多实验室在进行一些更小尺寸的研究。随着MOS管的尺寸不断的变小，沟道的不断变小，出现各种问题，如短沟道效应（DIBL、迁移率退化…）、栅极漏电、泄漏功率大等诸多问题，原先的结构开始力不从心，没有办法从现有的工艺制程中得到优良的结果，于是各个专家大佬不断的从材料、结构、工艺这三个方面找花样，解决问题，为下一代的工艺制程提供方案。
