  • How to test the surface resistivity of semiconductor materials

    Many important parameters of electronic devices are closely related to the resistivity and the uniformity of its distribution, such as the reverse saturation current of the diode, the saturation voltage drop of the transistor and the magnification β, etc., which are directly related to the resistivity of silicon single crystal. Therefore, the resistivity test of devices has become an important process in chip processing, and its uniformity control and accurate measurement are directly related to whether power devices with better performance can be manufactured in the future.

  • SEMI F47 Test in Semiconductor Industry —How does IT7800 edit the voltage transient drop waveform easily

    Background Semiconductor manufacturers have extremely high requirements on power supply, in particular the wafer related industry with higher requirements on power supply quality. Once voltage transient drop occurs, it will not only cause unexpected damage to sensitive microcomputer automatic control devices but also interrupt the process and cause great losses. To protect sensitive devices from voltage transient drop damage, the SEMI F47 standard stipulates the tolerance level of the semiconductor processing equipment on voltage transient drop, and requires that the semiconductor processing equipment should be immune to voltage transient drop in the AC power grid.
