Process Improvements

In addition, some high-efficiency diodes adopt multi-junction structures. Through the combination of multiple PN junctions or metal-semiconductor junctions, the performance of the devices is further optimized. The multi-junction structure can achieve a wider voltage operating range, reduce the on-resistance, and at the same time reduce the reverse recovery time (the time required for the reverse current of the diode to gradually decrease to zero when transitioning from the on state to the off state), thereby reducing switching losses and reverse recovery losses.

Process Improvements

Advanced manufacturing processes are crucial for realizing high-efficiency diodes. For instance, the ion implantation technique can precisely control the impurity concentration and distribution in semiconductor materials, thus optimizing the electrical properties of the devices. Fine lithography processes can fabricate device structures with smaller sizes, reducing parasitic capacitance, increasing the switching speed of the devices, and lowering switching losses. In terms of packaging processes, the use of low-impedance, high heat dissipation performance packaging materials and technologies can effectively reduce the losses caused by packaging and improve the heat dissipation capability of the devices, ensuring the stability and high efficiency of the devices during long-term operation.

high-efficiency diodes reduce energy losses such as conduction losses, switching losses, and reverse recovery losses from multiple dimensions through material innovation, structural optimization, and process improvements, thereby achieving efficient power transmission and conversion. With the continuous development of materials science and semiconductor technology, high-efficiency diodes will play an increasingly important role in more fields, promoting the advancement of electronic technology and power systems towards higher efficiency and better performance.
