Semiconductor Packaging Solutions
Semiconductor devices demand the highest level of protection. Our moisture-barrier and static-shielding packaging meets the stringent requirements of IC, wafer, and precision component handling.
Semiconductor Packaging Requirements
The semiconductor industry operates at the extreme edge of precision manufacturing โ and its packaging must match that precision. A single device can be worth hundreds of dollars, making packaging failures unacceptably costly.
Zero-Tolerance for ESD
Semiconductor devices โ ICs, wafers, transistors, and diodes โ are among the most static-sensitive products manufactured. Gate oxide layers measured in nanometers can be destroyed by discharges invisible to the human eye. Packaging must provide guaranteed Faraday cage shielding with no compromise on surface resistance consistency.
Cleanroom Compatibility
Packaging materials that enter semiconductor cleanrooms (ISO Class 5โ8) must be non-shedding, low-outgassing, and free from ionic contamination. Particulates at the micro-scale can cause patterning defects, and chemical residues can corrode bond pads. All materials must be certified cleanroom-safe.
Moisture Sensitivity Management
Moisture-sensitive devices (MSD) rated MSL 2 through 6 require packaging with verified moisture vapor transmission rates (MVTR). Inadequate moisture barriers lead to "popcorning" โ internal delamination during reflow soldering that destroys the device. IPC/JEDEC J-STD-033 compliance is non-negotiable.
Dimensional Precision & Consistency
Automated pick-and-place and tray-based handling systems demand packaging with tight dimensional tolerances. Bag width, length, and seal integrity must be consistent batch-to-batch to ensure compatibility with automated packaging lines.
Our Semiconductor Packaging Products
We offer two core product lines that together address the full spectrum of semiconductor packaging requirements โ from wafer handling to finished device shipping.
Static Shielding Bags โ Maximum ESD Protection
Our multi-layer metalized shielding bags are the industry standard for semiconductor device packaging. The buried aluminum layer creates a continuous Faraday cage that attenuates electrostatic fields, while the anti-static inner layer prevents tribocharging from device movement within the bag.
Key features for semiconductor:
- Surface resistance: < 10ยนยน ฮฉ (inner), < 10ยฒ ฮฉ (shield layer)
- Static decay: < 0.05 seconds (FTMS 101C, Method 4046)
- Heat sealable for hermetic closure
- Available with vacuum-sealable moisture barrier outer layer
Anti-Static Bags โ Process-Level Protection
For intra-facility transport, wafer cassette covers, and non-MSD device packaging, our anti-static bags provide reliable charge dissipation without the cost of full shielding. The pink anti-static formulation offers visual identification while the black conductive variant provides an economical shielding option for less critical devices.
Key features for semiconductor:
- Low outgassing โ suitable for ISO Class 7 cleanrooms
- Non-contaminating, amine-free formulation
- Available as flat bags, tubing, or ziplock configurations
- Custom printing with lot traceability codes
Quality Assurance for the Semiconductor Industry
Semiconductor packaging quality is not achieved by inspection โ it is built into every step of our manufacturing process. Here is how we ensure every bag meets the industry's most demanding standards.
Surface Resistance Testing โ Every Batch
We test surface resistance per ASTM D257 and GB/T 1410 on every production batch using calibrated megohmmeters. Results are documented on the Certificate of Analysis shipped with your order โ not spot-checked, not assumed, but verified and recorded.
IPC/JEDEC Standards Compliance
Our shielding bags are designed to meet the requirements of ANSI/ESD S20.20, JESD625-B, and IPC/JEDEC J-STD-033 for moisture-sensitive device handling. We stay current with industry standards and can adapt our products as requirements evolve.
Full Traceability
Every production batch is assigned a unique lot number linked to raw material certificates, in-process QC data, and final inspection records. If a question ever arises, we can trace any bag back to its manufacturing date, machine, operator, and material batch within hours.
Customer-Specific Qualification
We support customer qualification processes including first-article inspection reports (FAIR), sample submission for independent lab testing, and on-site audits. We treat qualification not as a hurdle but as the foundation of a long-term supply relationship.
