探讨了采用微波方法加工集成无源器件（IPD）、纳米ZnO辐射体和纳米多层压敏电阻（MLV）器件的可行性。方法微波烧结实验进行了使用多模，2.45 GHz的微波辐射器。详细研究了加热速率、冷却速率、保温时间、烧结温度等工艺参数对器件工艺的影响。对所得产物的微观结构、成分和电性能进行了表征。还审查了将实验室研究扩大到工业规模生产所涉及的各个阶段。发现使用微波处理MLV在小规模（约200个器件/批次）和大规模（约12000个器件/批次）烧结情况下都真正改善了电性能。对于独立的微波加热工艺，建议采用连续大规模生产的背靠背级联/传送带布置。然而，混合加热方法被发现提供堆叠操作的能力，并且除了提供在大体积上实现均匀温度的可能性之外，还有助于避免使用“箱装”。该技术似乎是有吸引力的，因为它的简单，快速，经济可行性和上级产品性能，在所有情况下实现的螺旋钻以及其普遍适用性。
The feasibility of employing the microwave methodology for the processing of integrated passive devices (IPDs), nanocrystalline ZnO radials and nano multilayer varistor (MLVs) devices was explored. Methodical microwave sintering experiments were carried out using a multimode, 2.45 GHz microwave applicator. Effect of various experimental parameters such as heating rate, cooling rate, soaking time, sintering temperature etc. on the processing of these device components was investigated in detail. The resultant products were characterized for microstructure, composition and electrical performance. The various stages involved in taking the laboratory research to industrial scale-up production were also examined. The use of microwaves for the processing of MLVs was found to genuinely improve the electrical properties in both small scale (-200 devices/batch) and large scale (-12000 devices/batch) sintering situations. For a stand alone microwave heating process a back-toback cascading/conveyer belt arrangement is recommended for continuous large scale production. However hybrid heating methodology was found to provide the capability of stacking operations and could be helpful in avoiding the use of ‘casketing’, besides providing the possibility of achieving uniform temperature across a large volume. The technique seems to be attractive in terms of its simplicity, rapidity, economic viability and the superior product performance achieved in all the cases augers well for its general applicability.
