Claim 0:
1. A low-k material, comprising:
a first ceramic with a low melting point dispersed in a second ceramic with a low melting point and a low dielectric constant, wherein the second ceramic are connected to form a network structure of a microcrystal phase,
wherein the first ceramic comprises (1) silicon oxide, magnesium oxide, aluminum oxide, calcium oxide, boron oxide, and zinc oxide,
wherein the silicon oxide and the magnesium oxide have a weight ratio of 100:0 to 100:85,
wherein the silicon oxide and the aluminum oxide have a weight ratio of 100:20 to 100:150,
wherein the silicon oxide and the calcium oxide have a weight ratio of 100:2 to 100:20,
wherein the silicon oxide and the boron oxide have a weight ratio of 100:2 to 100:70, and
wherein the silicon oxide and the zinc oxide have a weight ratio of 100:2 to 100:70;
or
wherein the first ceramic comprises (2) silicon oxide, aluminum oxide, calcium oxide, and boron oxide,
wherein the silicon oxide and the aluminum oxide have a weight ratio of 100:15 to 100:25,
wherein the silicon oxide and the calcium oxide have a weight ratio of 100:10 to 100:25, and
wherein the silicon oxide and the boron oxide have a weight ratio of 100:30 to 100:50.
