摘要: A low-k dielectric sacrificial material is formed within a microelectronic structure covered with a suitable porous or low density permeable material. At an appropriate time, the underlying sacrificial material is decomposed and diffused away through the overlying permeable material. As a result, at least one void is created, contributing to desirable dielectric characteristics.
摘要翻译: 在由适当的多孔或低密度可渗透材料覆盖的微电子结构内形成低k电介质牺牲材料。 在适当的时间,潜在的牺牲材料通过上覆的可渗透材料分解和扩散。 结果,产生至少一个空隙,有助于所需的介电特性。
