摘要: Conductive thick film compositions compatible to aluminum nitride, alumina and silicon nitride substrates for microelectronic circuit application. The conductive thick film composition includes first copper powder, second copper powder, and glass component. The conductive thick film composition further includes CU2O, Ag, and at least one metal element selected from Ti, V, Zr, Mn, Cr, Co, and Sn. After firing, the conductive thick film composition exhibit improved sheet resistivity, and improved adhesion with underlying substrate.
