Key Features & Advantages of Glass-Based Packaging
YEKGLASS applies decades of specialized glass manufacturing expertise to enhance the performance and reliability of semiconductor packaging solutions.
Our solutions deliver higher yields, better reliability, and a streamlined path toward next generation device designs.
Ultra-Precise Structuring
YEKGLASS uses proprietary glass molding and etching technologies to create micro scale features such as vias, cavities, channels, and edge defined structures with sub 30 μm accuracy. This precision allows complex integration with minimal edge chipping, making it ideal for MEMS, sensors, and high density IC packaging.
Thermal & Mechanical Stability
Instead of drilling vias and performing electroplating, we embed conductive metal pins during the glass wafer molding process. This single step approach minimizes mechanical stress, prevents microcracks, and ensures consistent pin to glass adhesion.
Dielectric Performance
Glass exhibits inherently low dielectric constant and low loss tangent, providing excellent electrical insulation and minimal signal interference at high frequencies. This makes it a superior material for RF modules, high speed signal lines, and optical communications where signal integrity is critical.
Hermetic & Reliable
With natural resistance to moisture, gas, and chemicals, glass substrates ensure true hermetic sealing protecting internal components from environmental damage. This reliability is essential in mission critical systems such as aerospace, medical, and high voltage electronics, where failure is not an option.
