The Secret Weapon of Precision Semiconductor Manufacturing: Diamond Grinding and Polishing Consumables – Boosting Wafer Yield and Performance!

In the rapidly evolving global semiconductor industry, every technological upgrade is a critical battle. Faced with increasingly complex precision processes and ever-harsher market competition, Honway deeply understands that improving wafer yield is no longer just a technical challenge; it’s the strategic core for seizing market opportunities and maximizing your return on investment.

What is a Semiconductor?

A semiconductor is a material that falls between a conductor and an insulator, uniquely characterized by its precisely controllable conductivity. Without external voltage, semiconductors typically don’t conduct electricity; however, once an appropriate voltage is applied, they can conduct, allowing current to flow. This property is the very core of modern electronic products.

From mobile phones and computers to various home appliances, and even the cloud services we use daily, all rely on semiconductor components. Integrated Circuits (ICs), made from semiconductor materials, perform logical operations by controlling the on-off state of electrical current. The two most basic semiconductor components are: Diodes and Transistors. The former one is a one-way switch that allows current to flow in only one direction, the other is a two-way switch that allows current to flow in both directions). Engineers cleverly combine these components to achieve various complex circuit functions.

What are Compound Semiconductors?

In the past, Silicon (Si) was the mainstream semiconductor material. But as electronic products demanded increasingly higher performance, silicon’s physical limits gradually became apparent. This is where compound semiconductors emerged as a key solution to break through existing technological bottlenecks. These semiconductors are composed of two or more elements, such as the commonly heard Gallium Arsenide (GaAs), Gallium Nitride (GaN), and Aluminum Nitride (AlN), bringing more powerful capabilities to a new generation of electronic products.

Advantages of Compound Semiconductors Compared to Silicon:

• Higher electron mobility: Means faster processing speeds.
• Wider band gap and excellent thermal conductivity: Can withstand higher voltages and temperatures, providing more stable and reliable performance.
• Suitable for high-power, high-frequency, and extreme environments: Allowing them to operate stably under harsh conditions like high pressure, high heat, or even in space.

These exceptional characteristics enable compound semiconductors to be widely used in lighting, consumer electronics, automotive electronics, energy, telecommunications, data communications, military, defense, and aerospace fields.

The Evolution of Semiconductor Materials

The development of semiconductor materials can be broadly divided into three stages:

• First-generation semiconductors: Primarily elemental semiconductors such as Silicon (Si) and Germanium (Ge), mainly used for logic ICs and memory ICs.
• Second-generation semiconductors: Represented by compound semiconductors like Gallium Arsenide (GaAs) and Indium Phosphide (InP). They boast faster electron mobility and superior high-frequency characteristics compared to silicon. They are mainly applied in communication radio frequency (RF) components, playing a critical role in, for example, mobile phone power amplifiers (PAs).
• Third-generation semiconductors (Wide Band Gap Semiconductors): Also known as Wide Band Gap (WBG) semiconductors, they are currently a major focus. The primary materials are Silicon Carbide (SiC) and Gallium Nitride (GaN), with band gaps typically greater than 2.2 eV. Compared to the first two generations, the third generation demonstrates exceptional performance under harsh conditions such as high temperature, high pressure, and high current, offering higher energy conversion efficiency and lower losses, with immense potential in high-power and high-frequency applications. Simply put, a larger “band gap” means the semiconductor is more stable in high-pressure, high-heat environments.
