Silicone Solutions for MEMS & Sensor Packaging
Micro-Electro-Mechanical Systems (MEMS) and sensor modules are compact, highly sensitive electronics devices that require robust protection without compromising performance or accuracy. Silicone based materials play critical roles in these semiconductor packages by providing low stress encapsulation, electrical insulation, and environmental protection, helping preserve sensor sensitivity under thermal cycling, vibration, and harsh operating conditions.
Die attach and lid attach adhesives
Die attach and lid attach adhesives hold semiconductor packages together and protect sensitive chips during operation. Die attach adhesives bond the chip to the package base for stability, while lid attach adhesives seal the package to shield the device from moisture, dust, and mechanical stress.
Glob top and wire encapsulants
Glob top and wire encapsulants protect delicate wire bonds and chip surfaces from mechanical, thermal, and environmental stresses. Silicone based encapsulants provide excellent electrical insulation, stress relief, and thermal stability, helping prevent wire damage and improve durability.
Potting gels
Potting gels protect sensitive electronic and sensor devices by providing environmental sealing, mechanical stress relief, and durability. Silicone-based potting gels enable reliable encapsulation for compact sensor modules and consumer electronics.
Thermal Management for High-Performance Computing
For high-performance computing and AI devices, Thermal Interface Material 1 (TIM1) and lid adhesive solutions enable thermal and mechanical reliability in advanced packages. The continued increase in processor power density and package size will require TIM1 materials that deliver high thermal conductivity, low bond line thickness, and stable coverage to efficiently transfer heat from the die to the lid.
- TIM1 gels and adhesives: Deliver reliable heat dissipation from within the package. Designed to withstand warpage and thermal stress, they support next‑generation high performance computing and AI devices.
- Lid adhesives: Provide durable adhesion and mechanical integrity at the package level. Designed to bond silicon die and metal lids, they enable long‑term reliability under thermal and mechanical stress.
- Silicone hybrid solutions: Combine the flexibility and thermal stability of silicone with the strength and adhesion of organic resins, delivering a balanced solution for advanced semiconductor packaging.
- Silicone molding compounds: Silicone hotmelt cartridges are solid, solvent‑free molding materials designed for efficient silicone molding compound applications. After molding, the material cures to form a flexible, durable silicone encapsulant.
Packaging Materials for Advanced Interconnects & CPO
High-speed data communication and advanced computer systems require semiconductor packaging materials that enable ultra-fast signal transmission, low loss of power, and high reliability. By offering excellent dielectric performance, thermal stability, and mechanical compliance, silicone-based materials like optical encapsulants, adhesives, silicone hybrids, and hot melt films enable the continued scale up of AI accelerators, data centers, and co packaged optics.
PIC/EIC attach adhesives are critical to integrating photonic (PIC) and electronic integrated circuits (EIC) in high-speed optical systems such as co-packaged optics (CPOs). Advanced silicone-based and hybrid attach adhesive solutions offer what these optical systems require in terms of alignment precision, adhesion strength, and long-term reliability, while maintaining excellent optical, thermal, and dielectric performance under demanding operating conditions.
Fiber bond adhesives enable precise and reliable fiber attachment in co‑packaged optics (CPOs). These adhesives offer excellent flowability for consistent V‑groove filling, combined with low‑modulus to minimize shift in optical alignment under thermal or mechanical stress. With high optical transmission, this material reduces signal loss amid high‑speed data paths, while its UV or low‑temperature curing options support integration with temperature‑sensitive components in advanced CPO architectures.
Benefits include:
- Viscosity adjustable: 50~5000cp
- CTE adjustable: 50~120ppm/C (@30~150C range)
- UV curability and adhesion can be adjustable by PAG package
- All prototypes can be cured at only heat condition (150C)
Encapsulants in co‑packaged optics (CPOs) protect optical interfaces while maintaining high signal integrity. Low‑stress, thermally stable silicone encapsulants help preserve alignment and reliability during thermal cycling, while their UV or low‑temperature cure options enable integration with sensitive optical components, making them well suited for tight‑tolerance CPO architectures where fiber alignment stability is critical.
Silicone hotmelt sheet molding materials for panel‑level packaging (PLP) are solid, pre‑formed silicone layers that are laminated onto panels and melted during molding to encapsulate devices. They enable uniform coverage, low stress on components, and excellent thermal and process stability, making them well suited for large‑area, high‑throughput PLP.
