本論文研究20wt%Cu/80wt%Al、30wt%Cu/70wt%Al、40wt%Cu/60wt%Al三種不同比例之銅鋁電極膏與20wt%CuNi/80wt%Al、40wt%CuNi/60wt%Al兩種比例之銅鎳鋁電極膏應用於LTCC內電極當中，而元件為5層結構，陶瓷材料為鈮酸鋇其K值為40，再透過空氣燒結研究內電極結構的變化。本論文主要分為以下三個部份去作探討。
第一部分為燒結溫度設定，比較直接燒結與二段燒結之好壞，決定使用二段燒結之後再透過DTA判斷合金的生成溫度，最後，使用TMA來決定陶瓷燒結緻密的溫度。
第二部分的研究重點在於對燒結後的LTCC陶瓷內電極進行微結構分析，主要觀察連續性、氧化和擴散這三個部分。連續性是指內電極的無斷裂和連接情況。通過觀察內電極的微結構，我們可以確定何種升溫速率下內電極的連續性最佳。其次，觀察氧化情況。在燒結過程中，內電極暴露在高溫環境下，容易氧化。氧化會導致內電極的電性能下降，甚至斷路。通過觀察內電極的氧化程度，我們可以判斷何種升溫速率下內電極的氧化程度較低，以確保較好的電性能。最後，觀察擴散是為了內電極在燒結過程中，電極材料有無分布在陶瓷層當中。
第三部分為電性分析，分析了並聯電容(Cp)、並聯電阻(Rp)、K(介電係數)、Q(品質因數)，在何種燒結情況下電性會達到最佳。

This paper investigates the application of different copper-aluminum and copper-nickel-aluminum electrode pastes for LTCC internal electrodes. Three ratios, 20wt%Cu/80wt%Al, 30wt%Cu/70wt%Al, and 40wt%Cu/60wt%Al, along with two ratios of 20wt%CuNi/80wt%Al and 40wt%CuNi/60wt%Al, are studied. The 5-layer structure comprises barium niobium with a K-value of 40, and structural changes of internal electrodes are explored through air sintering. Divided into three parts, the first evaluates sintering temperature settings, opting for two-stage sintering based on DTA results and TMA to determine ceramic sintering temperature. The second part analyzes microstructures focusing on continuity, oxidation, and diffusion. Optimal heating rates are determined for continuity, while observing oxidation effects on electrical performance. Diffusion phenomena confirm electrode material distribution during sintering. The third part focuses on electrical analysis, optimizing parallel capacitance (Cp), parallel resistance (Rp), K (dielectric coefficient), and Q (quality factor) under various firing conditions.
