随着绝缘栅双极型晶体管等功率器件的发展,对陶瓷敷铜基板(DBC)的需求越来越大。分别介绍了DBC基板的种类、结构,预氧化工艺对DBC基板的影响和敷接机理。用扫描电镜、X射线衍射等分析手段确定铜箔表面氧化后的物相成份,用X射线扫描确定敷接后界面空洞,并分析产生空洞的原因。用SEM观察界面的形貌并进行断面分析,用XRD和X-RAY分析界面产物的物相成份,从而确定DBC基板的敷接机理。
隨著絕緣柵雙極型晶體管等功率器件的髮展,對陶瓷敷銅基闆(DBC)的需求越來越大。分彆介紹瞭DBC基闆的種類、結構,預氧化工藝對DBC基闆的影響和敷接機理。用掃描電鏡、X射線衍射等分析手段確定銅箔錶麵氧化後的物相成份,用X射線掃描確定敷接後界麵空洞,併分析產生空洞的原因。用SEM觀察界麵的形貌併進行斷麵分析,用XRD和X-RAY分析界麵產物的物相成份,從而確定DBC基闆的敷接機理。

With the development of IGBT and power device, there is a higher demand for DBC. The article respectively describes the DBC category and structure, the affection the preformed oxidation to DBC and the bonding mechanism. The surface composition of the copper is confirmed by SEM and XRD, the void is conifrmed by X-ray, the paper also analyzed the causation to produce the void. The paper analyses morphology and section of the inter phase by SEM, and analyses the inter phase composition by XRD and X-RAY. The bonding mechanism is conifrmed.
