Low Dielectric Material
Shin-Etsu Chemical offers low dielectric materials which are suitable for 5G communication, millimeter wave radar, and large-capacity high-speed substrates.
SLK series having excellent high frequency characteristics of over 10 GHz are materials for wafer coats for high frequency applications, interlayer insulations and low dielectric substrates.
SLK series is an organic thermosetting resin with a low dielectric constant and a low dissipation factor close to fluorine-based materials, and supplied in varieties style to meets customer requirements such as liquid, solid, and film.
Quartz fabric (SQX series) is a core material for low dielectric substrates and a substrate material of prepreg.
Quartz fabric has an excellent low dielectric constant and dissipation factor compared to glass suitable for high-frequency substrate.
In addition, Quartz fabric is used for next-generation memory substrates as a solution of soft error problem due to having high purity and extremely low emission of alpha rays.
The CTE of Quartz fabric is 1/10 of the E glass which commonly used in FRP (reinforced plastic) applications. By using Quartz fabric as a base material, it is possible to manufacture the substrates with high dimensional stability.
