Physical and Dielectric Properties of Chemically-Driven Zero Shrinkage LTCC |
| 초록 |
The shrinkage variations create serious problems such as a mismatch of the stacking via pattern and a high device failure rate in LTCC (Low Temperature Co-fired Ceramics) production. There are several approaches to zero x-y shrinkage such as release tape technique and self-constrained tape technique. However, release tape technique requires additional procedure to eliminate the release tape through mechanical scrubbing. Self-constrained tape technique may cause delamination or macro-cracks due to poor mechanical integrity between the internal constraining tapes. This work demonstrates a new approach of producing zero x-y shrinkage without any additional experimental procedure such as scrubbing or secondary constraining layers. This new approach is based on new LTCC composition consisting of novel glass and ceramic filler. Physical and dielectric properties changed depending on glass and filler composition, which determine the chemical reactivity and densification behavior. Carefully-designed LTCC materials successfully demonstrated a zero x-y shrinkage under the common firing condition such as 850oC. Dielectric constants of 5-11 and loss tangents of ＜ 0.01 at 1MHz were obtained over different combinations between LTCC constituents. |
