High-Precision Plasma Cleaning for Semiconductor & Medical Technology

In high-tech manufacturing, even microscopic organic contamination can affect bonding quality, process stability and yield. Plasma cleaning is a dry surface preparation method used to reduce contamination before critical downstream steps such as bonding, coating, encapsulation or packaging.

Novel Tec supports customers with plasma solutions for semiconductor manufacturing and other sensitive applications. The focus is on technical consultation, suitable system selection, integration support and service for demanding production environments.

What does plasma cleaning do in advanced manufacturing?

Modern plasma treatment uses ionized gas to reduce hydrocarbons and other surface impurities at a very fine scale. Unlike conventional wet chemical cleaning methods, the process is dry and can be integrated into controlled manufacturing environments with fewer media handling steps.

Depending on the process and plasma chemistry, dry plasma cleaning can help improve wettability, support adhesion and prepare surfaces for the next production step. This makes the technology relevant for semiconductor packaging, electronics manufacturing and selected medical applications.

Plasma cleaning removes these contamination types:

• Organic films
• Weak boundary layers caused by release agents or process residues
• Moisture related surface films from ambient exposure and storage
• Light organic residues from tapes, adhesives and packaging materials
• Selected residues from previous production steps
• Native contamination accumulated during transport and storage

Plasma technology for bonding, coating & packaging steps

In semiconductor and electronics manufacturing, plasma cleaning is often used before processes where clean and stable interfaces are required. Typical examples include bonding, coating, underfill, molding and encapsulation steps.

A well controlled cleaning process can help reduce organic contamination before advanced packaging operations and support stable downstream performance. In this context, plasma surface treatment is particularly relevant where wet chemistry is difficult to integrate or where sensitive parts require a dry and controlled process window.

Typical use cases for plasma treatment

Hybrid bonding

Plasma cleaning helps reduce organic contamination before hybrid bonding processes and supports stable surface conditions for the next bonding step.

TCB

For TCB processes, plasma cleaning is used to prepare sensitive surfaces before bonding and to support stable downstream process conditions.

Thermal compression bonding

Before thermal compression bonding, plasma surface treatment can help reduce contamination and improve surface readiness for demanding packaging applications.

Micro bump bonding

In micro bump bonding, plasma cleaning is used as a dry preparation step before bonding in order to reduce surface contamination and support reliable interconnect formation.

Plasma cleaning - questions & answers

What is plasma cleaning used for?

Plasma cleaning is used to reduce organic contamination on surfaces before bonding, coating, encapsulation or packaging steps. It is widely used in semiconductor, electronics and selected medical applications.

What materials can be treated with plasma cleaning?

Typical materials include silicon wafers, metals, glass, ceramics and selected polymers. Suitability depends on the substrate, contamination type and process parameters.

Is plasma cleaning suitable for sensitive electronic devices?

Yes. By using potential-free atmospheric plasma technology from Surfx, no harmful electrical potential builds up on the component. This makes the process safe even for sensitive RF electronics and active semiconductor structures.

Can plasma cleaning be used for inline production?

Yes. Atmospheric plasma systems in particular can be integrated into inline and automated production environments, depending on the application and equipment concept.

How can a suitable plasma treatment process be evaluated?

A suitable process is typically defined based on substrate type, contamination profile, downstream requirements and production environment. Novel Tec supports customers with technical consultation and system related guidance.
