    摘要: A method of fabricating shallow trench isolation. In the method, a refill step of oxide layer and a step of forming a sacrificial layer on the semiconductor substrate are applied after filling insulating layer into the shallow trenches. The purpose of the steps is to protect the oxide layer on the semiconductor substrate and the corner of the shallow trenches, used to isolate the STI.

    摘要: A fabrication method for a damascene bit line contact plug. A semiconductor substrate has a first gate conductive structure, a second gate conductive structure and a source/drain region formed therebetween. A first conductive layer is formed in a space between the first gate conductive structure and the second gate conductive structure to be electrically connected to the source/drain region. An inter-layer dielectric with a planarized surface is formed to cover the first conductive layer, the first gate conductive structure, and the second gate conductive structure. A bit line contact hole is formed in the inter-layer dielectric to expose the top of the first conductive layer. A second conductive layer is formed in the bit line contact hole, in which the combination of the second conductive layer and the first conductive layer serves as a damascene bit line contact plug.

    摘要: A method of forming contact holes. A substrate on which a plurality of gate structures is formed is provided, wherein the gate structure comprises a gate, a gate capping layer, and a gate spacer. An insulating layer is formed on the gate structures and fills between the gate structures. The insulating layer is etched using the gate capping layers, the gate spacers, and the substrate as stop layers to form first contact holes between the gate structures to expose the substrate and the gate spacers and form second contact holes overlying each gate structure to expose the gate capping layers. A protective spacer is formed over each sidewall of the first contact holes and the second contact holes. The gate capping layer under each gate contact hole is etched using the protective spacer as a stop layer to expose the gate. The protective spacers are removed.

    摘要: A method of forming inter-metal dielectric (IMD). A substrate having a patterned metal layer thereon has at least one opening to expose the substrate. The opening has an aspect ratio of 3.5˜4.5. Next, the opening is filled with a first dielectric layer, and voids are formed in the upper portion of the first dielectric layer due to the high aspect ratio opening. Thereafter, the first dielectric layer is etched to leave the first dielectric layer with a predetermined height in the opening without voids. Finally, a second dielectric layer is formed on the first dielectric layer to completely fill the opening.
