  • Publication number: 20080157291
    Abstract: One or more passivation layers are added to the end of a semiconductor process flow to provide additional protection for devices (e.g., transistors) formed during the process. An additional layer is then formed and/or an anneal is performed to mitigate threshold voltage shifting that may be induced by the passivation layers. Mitigation of threshold voltage shifting increases the life expectancy of devices (e.g., transistors) formed during the process, which in turn mitigates yield loss by facilitating predictable or otherwise desirable behavior of the devices (e.g., transistors).

  • Publication number: 20080017928
    Abstract: Disclosed are a semiconductor device and a method for manufacturing the same. The semiconductor device can include at least two gate structures spaced apart from each other on a semiconductor substrate, a silicon nitride layer covering the semiconductor substrate and the gate structures, an interlayer dielectric layer on the silicon nitride layer, and a buffer layer interposed between the silicon nitride layer and the interlayer dielectric layer to buffer stress between the silicon nitride layer and the interlayer dielectric layer. The buffer layer has a tensile stress characteristic, while the silicon nitride layer and the interlayer dielectric layer have a compressive stress characteristic. Therefore, the buffer layer buffers the compressive stress of both the silicon nitride layer and the interlayer dielectric layer. Accordingly, the delamination or the damage of the silicon nitride layer and the interlayer dielectric layer is inhibited.

    Abstract: When microfabrication is done, a reliable semiconductor device is offered. A semiconductor device has a semiconductor substrate which has a main front surface, a plurality of convex patterns formed on the main front surface of a semiconductor substrate so that each might have a floating gate and a control gate, a first insulating film formed so that the upper surface and the side surface of each of a plurality of convex patterns might be covered, and so that width might become large rather than the portion which covers the lower part side surface of a convex pattern in the portion which covers an upper part side surface, and a second insulating film that covers the upper surface and the side surface of the first insulating film so that the cavity between the adjacent convex patterns may be occluded. The position occluded by the second insulating film of a cavity is a position higher than the upper surface of a floating gate, and is a position lower than the upper surface of a control gate.

  • Patent number: 7317220
    Abstract: A semiconductor assembly providing even nucleation between silicon and oxide surfaces for growing uniformly thin silicon nitride layers used in semiconductor devices is disclosed. First, a nonconductive nitride-nucleation enhancing monolayer is formed over a semiconductor assembly having both nitridation receptive and resistive materials. For purposes of the present invention, a nitride-nucleation enhancing monolayer is a material that will readily accept the bonding of nitrogen atoms to the material itself. Next, a silicon nitride layer is formed over the nonconductive nitride-nucleation enhancing monolayer. The nonconductive nitride-nucleation enhancing monolayer provides even nucleation over both the nitridation receptive material and the nitridation resistive material for silicon nitride, thereby allowing for the growth of a uniformly thin nitride layer.
