Sulfur-Free Packaging Paper for Semiconductor Chips
Description
Sulfur-Free Packaging Paper for Semiconductor Chips is a high-cleanliness industrial packaging material designed for IC chips, wafers, package substrates, and other sensitive electronic components. Its core feature is the absence of free sulfur or sulfides, preventing sulfur from reacting with metal electrodes (such as copper, silver, and aluminum), thus avoiding corrosion, sulfide tarnishing, and performance degradation.
✅ Main Functions
Prevent Metal Corrosion / Sulfuration
Chip terminals and pads often contain copper, silver, or aluminum. Sulfur-free paper helps prevent sulfide reactions that cause blackening and poor contact.
Isolation Protection
Physically isolates external moisture, particles, and contaminants.
Clean Packaging
Reduces micro-dust and fiber shedding to meet high-purity requirements.
Storage & Transportation Protection
Protects chip surfaces during handling, transfer, transportation, and warehousing.
✅ Why Must Semiconductors Use Sulfur-Free Packaging Paper?
Chip electrodes and pads are highly sensitive to sulfur.
Ordinary paper contains sulfur, which reacts with copper or silver → forms sulfides → leading to:
❌ Terminal blackening
❌ Reduced solderability → poor solder joints
❌ Electrical instability
❌ Shortened lifespan
❌ High failure risk
Therefore, semiconductor packaging must use sulfur-free paper with extremely low sulfur content to ensure reliability.
✅ Key Features
| Feature | Description |
|---|---|
| Sulfur-free composition | <0.1% or lower per industry requirements |
| High cleanliness | Low dust / low fiber shedding |
| Chemical stability | No chemical reaction with metals |
| High-temperature resistance | Can be used in FOL and other thermal processes |
