  • Patent number: 11189733
    Abstract: Techniques are disclosed for forming thin-film transistors (TFTs) with low contact resistance. As disclosed in the present application, the low contact resistance can be achieved by intentionally thinning one or both of the source/drain (S/D) regions of the thin-film layer of the TFT device. As the TFT layer may have an initial thickness in the range of 20-65 nm, the techniques for thinning the S/D regions of the TFT layer described herein may reduce the thickness in one or both of those S/D regions to a resulting thickness of 3-10 nm, for example. Intentionally thinning one or both of the S/D regions of the TFT layer induces more electrostatic charges inside the thinned S/D region, thereby increasing the effective dopant in that S/D region. The increase in effective dopant in the thinned S/D region helps lower the related contact resistance, thereby leading to enhanced overall device performance.

    Abstract: A color filter substrate and a liquid crystal display panel are provided. The color filter substrate includes photoresist blocks spaced apart, a black matrix disposed between adjacent photoresist blocks, an optically thinner medium film disposed on the photoresist blocks and the black matrix, and an overcoat layer covering the photoresist blocks, the black matrix, and the optically thinner medium film. The optically thinner medium film covers a boundary between the photoresist blocks and the black matrix. A refractive index of the optically thinner medium film is less than that of the overcoat layer. The color filter substrate and a TFT array substrate are formed into the liquid crystal display panel. Light is totally reflected at an interface between the overcoat layer and the optically thinner medium film, thereby solving issues of color shifts at large viewing angles without affecting transmittance of the liquid crystal display panel.
