Application scenarios of single-crystal siliconized wafers in the discrete device manufacturing field

Currently, the pace of capacity expansion for discrete devices in China continues to accelerate. The penetration rate of single-crystal silicon polishing wafers—key front-end consumables—has exceeded 60%, effectively reducing surface stress on wafers and lowering defect rates in downstream processes.

Substrate Applications in the Manufacturing of Power Diodes

Industry consensus holds that employing compliant monocrystalline silicon passivation can improve diode turn-on stability by more than 12%, while mitigating the impact of surface lattice damage incurred during wafer dicing on the device’s ultimate performance. Currently, most leading domestic diode manufacturers have integrated this passivation process into their standard production workflows.

Surface Pre-treatment Applications in the Thyristor Manufacturing Process

The pre‑treatment process for producing silicon‑on‑insulator wafers compatible with thyristors can be divided into three steps:

1. After wafer dicing, the wafers are directly fed into the chemical‑mechanical polishing (CMP) process, replacing the conventional coarse‑grinding step.
2. By controlling the corrosion depth, the surface roughness is maintained within 0.5 μm.
3. Subsequently, the process proceeds directly to ion implantation, thereby eliminating two additional polishing steps.

This process can increase the production efficiency of a single batch of thyristors by approximately 18% and reduce overall consumable‑related costs.

Application scenarios of single-crystal silicon passivated wafers in the photovoltaic renewable energy sector

In 2026, the pace of technological advancement in China’s photovoltaic industry is accelerating, with the application of monocrystalline silicon wafers expanding from industrial‑grade cells to the distributed PV sector, driving sustained growth in market demand.

After undergoing a passivation process, monocrystalline silicon substrates can effectively enhance the uniformity of adhesion of the rear-side passivation layer, thereby boosting the photoelectric conversion efficiency of N-type cells by 0.3 to 0.5 percentage points. This represents a key technological pathway for reducing costs and improving efficiency in today’s TOPCon solar cells.

Auxiliary Material Support for Distributed Photovoltaic Modules

Some small-scale distributed photovoltaic systems employ custom‑made monocrystalline silicon wafers as a cushioning substrate for the busbars, thereby reducing the likelihood of module cracking under harsh outdoor conditions and extending the overall service life of the system.
