The dielectric constant, k, is a parameter defining ability of material to store charge. In Si technology the reference is a value of k of silicon dioxide, S i O 2, which is 3.9. Dielectrics featuring k>3.9 are referred to as “high”-k dielectric while dielectric featuring k<3.9 are defined as “low”-k dielectrics. green earth gummies
