Static Control
Static Control Solutions for the Semiconductors and LCDs Industry
Any amount of static electricity cause problems during semiconductor and LCD manufacturing. Charge builds up quickly during wafer testing, die bonding, and film removal. Anti-static solutions reduce the need for rework and defects in the manufacturing process.
Why Static is Critical in Precision Electronics
Even small amounts of static electricity cause serious problems during semiconductor and LCD manufacturing. Charge builds up quickly during wafer testing, die bonding, and film removal. It damages circuits, pulls particles into clean zones, and introduces defects that often go undetected until final testing.
These aren’t isolated issues. In flat panel production, static turns cleanroom surfaces into dust traps. It also interferes with weighing systems, triggers misread at inspection stations and disrupts alignment during precision placement.
Product Solutions for Effective Static Control for Semiconductors
Different stages of production require different formats. Bar-type ionizers cover wide areas like panel lines and transfer stations. Spot-type models target narrow spaces near bonders or sensors. Blower units work across benches and larger zones without the need for external air. Each format fits into existing setups with minimal modification and supports continuous operation without manual recalibration.
Benefits of KEYENCE’s Static Control Solutions for Semiconductor and LCD Industries
KEYENCE offers a full lineup of ionizers built for production-critical environments. For example, the SJ-H Series covers wide areas without the need for external air, making it ideal for cleanrooms and transfer zones. The SJ-E Series combines high-speed neutralization with reduced operating costs, using a supersonic airflow structure and optimized electrode layout to cut air consumption by up to 60%.
Each model is designed for consistent performance over long runs. Ion output remains steady even as charge levels or environmental conditions change. Real-time monitoring and automatic correction reduce manual adjustments, helping maintain throughput without adding extra checks.

Applications of Static Control Solutions
Wafer probe stations use ionizers to prevent charge buildup at contact points. During film removal, charge control reduces particle attraction. Die bonders need rapid neutralization to avoid discharge during die release. LCD lines use LCD static eliminators to protect glass during handling and transfer. Test handlers rely on static control to reduce latent failures in final units.
KEYENCE ionizers also support air shower zones and packaging areas, where a stray charge can pull in contaminants or cause issues with seal integrity. Each system is selected based on the risks tied to the specific process, not based on a one-size-fits-all model.
Preventing Static Electricity During Wafer Testing
Reliable static elimination is possible in wafer testing environments by installing a feedback sensor near the target to enable constant monitoring of the target area.
Eliminating Static When Peeling Protective Film from Wafers
Static electricity can be eliminated quickly over a wide area. Recording static elimination results during peeling makes it possible to identify the cause of problems.
Static Electricity Prevention During Die Bonding
Using high-speed static elimination to prevent discharges during die releasing helps reduce maintenance that would otherwise be necessary with conventional devices.
Test Handler ESD Protection and Quality Assurance
With a high-performance ion balance of ±1 V, the device can be used safely in any semiconductor manufacturing site. Previous static elimination results can also be checked to identify affected periods in the event of a problem.
Static Elimination During Fork Transferring of Liquid Crystal Glass
Airless and energy-saving ionizers help reduce air consumption in a factory while ensuring advanced static elimination performance.
Static Elimination During Air Showers
Installing ionizers in air shower rooms—where the risk of introducing foreign particles into a clean room is highest—helps improve dust removal effectiveness.
Precision, Safety, and Anti-Contamination Benefits
Once static takes hold, it’s harder to keep particles out and product quality up. Anti-static solutions reduce the need for rework and catch fewer defects late in the process. They also support cleanroom standards without relying on high airflow or external grounding. In sensitive areas, static control helps keep surfaces clean, readings stable, and tools operating without interruption.
Selecting the Right Static Control Solution for Your Semiconductor and LCD Production Line
Choosing the right ionizer depends on more than layout. Some areas can’t support airflow, while others need compact units with no exposed wiring. KEYENCE offers bar, blower, and spot-type models that fit tight spaces, maintain ion balance automatically, and integrate easily with existing tools. Each option is designed to solve specific problems without disrupting the line.
