1. Material Quality: Using high-grade semiconductor materials with minimal defects reduces leakage and breakdown risks. 2. Insulating Layers: Insulating layers like oxides prevent unintended leakage paths by dividing device regions. serves to partition distinct regions within the device, effectively impeding unintended leakage paths. These layers are meticulously grown or deposited to achieve precise thickness and ensure optimal functionality. 3. Reliability Testing: Rigorous reliability tests identify potential failure causes related to leakage and breakdown, ensuring dependable device performance in varied conditions.

Designing the semiconductor device with appropriate dimensions and doping profiles can help minimize junction leakage. This involves careful consideration of the doping concentration, junction depth, and the overall device structure.

The most effective way to solve the diode leakage current is to use anti-leakage diodes, which can reduce the leakage current and improve the performance of the circuit. In addition, if necessary, a blocking capacitor can also be added to the diode two-pole circuit to suppress leakage. In addition, the correct circuit configuration is also an important factor in suppressing leakage. Avoiding open circuits and short circuits in the circuit and maintaining the correct use of capacitors can effectively reduce diode leakage current.

In modern semiconductor devices, the introduction of high-k materials has revolutionized the performance of junctions. High-k dielectrics, such as hafnium oxide (HfO2), are used to replace traditional silicon dioxide (SiO2) as gate insulators in transistors. These materials have a higher dielectric constant, which allows for a thinner insulating layer without compromising the electric field strength. This is particularly important in FinFET and Gate-All-Around (GAA) transistor architectures, High-k materials help maintain the effectiveness of the gate control over the channel, thereby improving the subthreshold swing and reducing the short-channel effects that can occur in smaller devices.
