Paper Abstract

Spin-On Glass (SOG) is used as a planarizing component of the interlevel dielectric in a multilevel integratedcircuit (IC). However, the presence of SOG may compromise IC performance due to water absorption. Several effects will be discussed in the present talk: "Poisoning" of contacts between two metallization levels. Accelerated hot-carrier aging of the MOS transistor.• Formation of mobile positive charge in the SOG layer. The magnitude of this charge may be high enough to invert the silicon surface.• Many-fold increase in the SOG dielectric constant and related increase in parasitic capacitance of the IC.
