微波等离子体化学气相沉积技术（MPCVD）是一种用于薄膜沉积的技术，主要用于制造高质量的薄膜和涂层。这项技术包括：（1）使用微波激发等离子体（通常在2.45GHz或915MHz）。（2）等离子体中的气相反应与表面反应。（3）不同工艺参数下的沉积过程。在COMSOL案例库中“微波腔等离子体反应器”（ID:115681）该模型搭建了微波与等离子体之间的桥梁。我们希望在此基础上解决气相反应与表面反应，并对沉积过程进行初步分析。 我们模拟了这样一个状态，即在微波等离子体过程达到稳态后，利用此时的电磁参数与等离子体参数，作为化学气相沉积的初始条件与边界条件 ... Per saperne di più
