Nordson MARCH AP-300 plasma cleaner

The Nordson MARCH AP-300 is a compact, cost-effective benchtop vacuum plasma system. Its core strength lies in the integration of a 13.56 MHz RF power supply and an automatic impedance matching network, enabling it to deliver exceptional, stable, and uniform plasma processing results within a compact footprint.

**Operating Principle**

The AP-300 operates by utilizing a vacuum pump to evacuate the chamber to a high-vacuum state, after which specific process gases are introduced. By applying 13.56 MHz RF energy, the gas is ionized to form a plasma. High-energy particles and reactive species within the plasma engage in physical bombardment or chemical reactions with the material surface, thereby achieving surface cleaning, activation, or etching.

**Core Functions and Applications**

The primary function of the AP-300 is to provide a stable and controllable plasma environment. It primarily optimizes the quality and reliability of final products through three key mechanisms:

**Function Category** | **Implementation Method and Effect**

**Plasma Cleaning** | Removes organic contaminants and oxides from material surfaces, achieving atomic-level cleanliness.

**Surface Activation** | Introduces polar functional groups—such as hydroxyl and carboxyl groups—onto the material surface, thereby increasing surface energy and wettability to enhance adhesion with other materials.

**Etching / Descum** | Utilizes fluorine-containing process gases (e.g., CF₄) to perform precise anisotropic or isotropic etching at micron or even nanometer scales; capable of removing photoresist residues from wafers.

**Key Advantages and Features**

The design of the AP-300 strikes an exquisite balance between performance and flexibility within a compact space. Its key features are outlined below:
