  • Publication number: 20080009108
    Abstract: A display panel structure having a circuit element disposed thereon and method of manufacture are provided. The display panel includes a substrate and the circuit element disposed on the substrate. The circuit element has a first interface layer and a first conductive layer. Both the first interface layer and the first conductive layer have copper materials. The material which makes the first interface layer includes a reactant or a compound of the material which makes the first conductive layer. The method for manufacturing includes the following steps: forming a first interface layer on the substrate; forming a first conductive layer on the first interface layer; and etching the first conductive and interface layers to form a pattern. The existence of the first interface reduces the penetration of the first conductive layer on the substrate and improves the adhesive force between the first conductive layer and the substrate.

  • Patent number: 5482876
    Abstract: A field effect transistor which is not susceptible to mask edge defects at its gate spacer oxides. The transistor is formed upon a (100) silicon semiconductor substrate through successive layering of a gate oxide, and a gate electrode. A pair of gate spacer oxides is then formed covering opposite edges of the gate oxide and the gate electrode. A screen oxide is then formed over the surface of the semiconductor substrate, the gate and the gate spacer oxides. The upper surface of the screen oxide has an angle of elevation not exceeding 54.44 degrees with respect to the semiconductor substrate. The screen oxide also smoothly flows from thicker regions at the junctures of the gate spacer oxides and the semiconductor substrate to thinner regions over the surface of the semiconductor substrate. The semiconductor substrate adjoining the gate spacer oxides is then ion implanted through the screen oxide to form amorphous source/drain electrodes.
