Hydrogen Peroxide

The principle of hydrogen peroxide good for cuts:

 

Oxidation reaction:
When H ₂ O ₂ decomposes, hydroxyl radicals (· OH) and oxygen (O ₂) are generated. These reactive oxygen species can oxidize and decompose organic compounds or certain inorganic materials (such as metals and semiconductor materials).
-For example, in silicon wafer etching, H ₂ O ₂ works synergistically with hydrofluoric acid (HF) to generate silicon dioxide (SiO ₂) on the surface of silicon oxide, which is then dissolved by HF to achieve precise cutting.
Catalytic decomposition:
-Metal ions (such as Fe ² ⁺, Cu ² ⁺) or enzymes (such as catalase) can accelerate the decomposition of H ₂ O ₂, releasing a large amount of oxygen and heat. This intense reaction can locally damage the material structure and is suitable for microfabrication or biological tissue treatment.
Selective etching:
-In semiconductor processes, H ₂ O ₂ is often mixed with other acids such as sulfuric acid and hydrofluoric acid. By adjusting the concentration and temperature, specific material layers (such as photoresist and metal films) are selectively etched to achieve high-precision patterned cutting.

Application areas of hydrogen peroxide good for cuts:

Microelectronics and Semiconductor Manufacturing:
Photoresist removal:
H ₂ O ₂ is mixed with sulfuric acid to form a "Piranha solution" (H ₂ SO ₄: H ₂ O ₂), which efficiently peels off photoresist and cleans the wafer surface.
Metal etching:
In the processing of printed circuit boards (PCBs), H ₂ O ₂ and hydrochloric acid (HCl) are mixed to etch copper layers, forming circuit patterns.
Silicon wafer processing:
Used for cleaning and etching the surface of silicon wafers, removing contaminants or oxide layers.
