The main six specific processes of SiC chip manufacturing are pre-processing, wafer processing, crystal growth, integrated circuit design and fabrication, chip testing, and integration.
The voltage drop of silicon carbide (SiC) diodes refers to the electromotive force difference of SiC diodes. Silicon carbide diode is a semiconductor device with a P-N junction structure that can be used to control current or voltage. The voltage drop of a diode refers to the electromotive force difference between the P-N junction of the diode in the forward conducting state, that is, the forward bias voltage. This is due to the potential difference between the contact surfaces in the diode.
When using silicon carbide (SiC) diodes, some safety factors should be taken into account, such as avoiding excessive current flowing through the diode to prevent damage. During use, attention should also be paid to circuit design and diode selection to ensure optimal system performance.
Silicon carbide diodes are unipolar devices, so compared to traditional silicon fast recovery diodes (silicon FRDs), silicon carbide diodes have ideal reverse recovery characteristics. When the device switches from forward to reverse blocking direction, there is almost no reverse recovery power, and the reverse recovery time is less than 20ns. Even the reverse recovery time of 600V10A silicon carbide diodes is less than 10ns.
The circuit symbol of silicon carbide (SiC) MOSFET is similar to that of traditional silicon MOSFET, except that some special markings are added to the symbol to indicate its characteristics.
In a P-channel Enhanced Mode FET, VDS represents the voltage between the drain and source, while CGS represents the capacitance between the gate and source. When calculating VDS, it is necessary to consider the working state of the P-Channel Enhanced Mode FET. Generally, the following formula can be used for calculation:
Silicon carbide (SiC) diodes have low switching losses, high reverse withstand voltage, and thermal stability, and have been widely used. Here are the usage and testing methods for SiC diodes:
