Latest Patents

One of her latest patents is titled "DRAM contact process by localized etch-stop removal." This patent describes a method for removing an etch-stop layer, such as Si₃N₄, from the vicinity of contact openings. The need for this removal arises when the etch-stop layer's surface is exposed during processing, especially when the substrate is subjected to temperatures exceeding 700°C. The high intrinsic interfacial stress in Si₃N₄ can lead to cracks that emanate from the corners of contact openings, which can compromise the reliability of the contacts due to moisture adsorption and contamination. Additionally, uneven etching can cause protrusions of the etch-stop layer within contact openings, creating weak spots along the contact walls. Timely removal of the etch-stop layer around the contact openings effectively eliminates these protrusions, enhancing the overall performance of the semiconductor devices.
