    • A method for manufacturing a via structure comprising the steps of providing a semiconductor substrate, and then forming conductive line and dielectric layer over the substrate. Next, a photolithographic and a first etching operation are conducted so that an opening in the dielectric layer exposing the conductive line surface is formed. The first etching operation uses several etchants including fluorobutane, which has the highest concentration. Since there is a re-entrance structure at the bottom of the opening, a second etching operation is performed. In the second etching operation, a portion of the conductive line is etched for a fixed time interval to control the degree of etching. Consequently, a slanting surface is formed at the bottom of the opening and the re-entrance structure is eliminated. With a planarized bottom, step coverage of subsequently deposited material is increased.

    • A self-aligned via process to prevent the via poisoning includes forming a hydrogen silsesquioxane layer on the substrate and over a pre-formed metal layer, forming an etching stop layer on the hydrogen silsesquioxane layer, forming an oxide layer on the etching stop layer, and then proceeding with a two-step etching process to form a via. The two-step etching process first patterns the oxide layer using a patterned photoresist layer as a mask, and then patterns the etching stop layer together with the hydrogen silsesquioxane layer using the patterned oxide layer as a mask. Because the etching stop layer prevents the hydrogen silsesquioxane layer from reacting with the oxygen plasma during the photoresist layer removal process, via poisoning is eliminated.
    • 用于防止通路中毒的自对准通孔工艺包括在基板上和预成型的金属层上形成氢倍半硅氧烷层,在氢倍半硅氧烷层上形成蚀刻停止层,在蚀刻停止层上形成氧化物层, 然后进行两步蚀刻工艺以形成通孔。 两步蚀刻工艺首先使用图案化的光致抗蚀剂层作为掩模对氧化物层进行图案化,然后使用图案化氧化物层作为掩模,将蚀刻停止层与氢倍半硅氧烷层一起图案化。 因为蚀刻停止层防止在光致抗蚀剂层去除过程中氢倍半硅氧烷层与氧等离子体反应,消除了中毒。

    • A method of making vias in a semiconductor IC device having adequate contact to the surface of the interconnects and without inadequate landing is disclosed. The method has interconnects formed in a metal layer on the substrate of the IC device, and a first dielectric layer is formed covering the surface of the interconnects. An etch-stopping layer is then formed on top of the first dielectric layer, followed by the formation of a second dielectric layer on top of the etch-stopping layer. A photoresist layer then covers the second dielectric layer and reveals the surface regions of the second dielectric layer designated for the formation of the vias. A main etching procedure is then performed to etch into the second dielectric layer down to the surface of the etch-stopping layer, thereby forming the first section of the vias. An over-etching procedure is then implemented to strip off the etch-stopping layer and further etches into the first dielectric layer and the etching is then stopped when the surface of the interconnects are revealed to conclude the formation of the vias.
