Abstract

The invention belongs to the technical field of semiconductor manufacturing, and particularly relates to hole-filling printing paste for HTCC and a preparation method of the hole-filling printing paste. The pore-filling printing paste is composed of the following raw materials in parts by weight: 75-85 parts of metal powder, 9-12 parts of an inorganic additive and 8-10 parts of an organic carrier, the metal powder is tungsten powder or mixed powder composed of tungsten powder and molybdenum powder, and the inorganic additive is composed of aluminum oxide and silicon dioxide according to the weight part ratio of (7-10): (1-3). The organic carrier is composed of a solvent, a slurry auxiliary agent and a binder according to a weight part ratio of (6-10): (0.03-0.06): (0.5-2). Through selection of the types and proportions of the raw materials, good flatness after slurry hole filling and sintering is realized, downstream processing procedures are not affected, and the yield is high.

Description

technical field [0001] The invention belongs to the technical field of semiconductor manufacturing, and in particular relates to a hole-filling printing paste for HTCC and a preparation method thereof. Background technique [0002] Functional ceramic materials provide important support for modern electronic information technology, and are widely used in energy, communication, household appliances, automobiles and other fields. Co-fired multilayer ceramic substrates use thick-film technology to embed passive components such as signal lines and micro-wires into the substrate to meet many requirements of integrated circuits, and have received more and more attention. Co-fired multilayer ceramic substrates can be divided into high-temperature co-fired multilayer ceramic (HTCC) substrates and low-temperature co-fired multilayer ceramic (LTCC) substrates. Among them, alumina ceramic substrates have high thermal conductivity, high electrical insulation strength, Low dielectric con...
