Abstract: Methods of forming field effect transistors include the steps of forming a composite of layers including an amorphous silicon layer (a--Si), a silicon dioxide layer thereon and a silicon nitride layer on the silicon dioxide layer. A polycrystalline silicon conductive layer is then formed on the silicon nitride layer by depositing and patterning polycrystalline silicon. The polycrystalline silicon conductive layer is then oxidized using thermal oxidation techniques to form an oxide outerlayer. During this step, a portion of the polycrystalline silicon conductive layer will be consumed to define a gate electrode. Dopants of first conductivity type are then implanted into a top surface of the silicon nitride layer, using the oxide outerlayer and the gate electrode as a mask, to form relatively lightly doped preliminary source and drain regions in the amorphous silicon layer. The oxide outerlayer is then removed preferably using a buffered oxide etchant (BOE) solution which does not etch silicon nitride.

Abstract: A poly-silicon thin film transistor having LDD structure which has very low source/drain resistance is described. A TFT according to a preferred embodiment of the present invention, has, on a substrate, an active poly-silicon layer with a heavily-doped region on an outer peripheral thereof, a lightly doped region on ban inside the outer peripheral band and an un-doped region on a center part thereof. A gate insulating layer is comprised of a lower oxide layer, a nitride layer and an upper oxide layer. The lower oxide layer is formed over the whole active poly-silicon layer, but the nitride layer and the upper oxide layer are formed only on the un-doped portions of the active poly-silicon layer. A gate electrode is then formed on the upper oxide layer. A method for forming this structure is also described, which method uses a dry etch to remove the upper oxide layer and the nitride layer, but not the lower oxide layer prior to ion implantation of the active region.

Abstract: An interconnecting method for a semiconductor device is disclosed in which a conductive layer containing aluminum is formed on a lower structure formed on a substrate. An insulating layer is formed on the conductive layer. A photoresist pattern for defining a portion where an opening is to be made is formed on the insulating layer. Then, the insulating layer is isotropically etched by wet etching with the photoresist pattern as an etching mask. The insulating layer remaining after the isotropical etching is taper-etched by RIE to form the opening. To ensure that the conductive layer is exposed by the opening, the resultant structure is overetched by using a mixed gas of fluorocarbon-containing gas and oxygen. This resultant structure is RIE-sputtered using fluorocarbon-containing gas such that polymer or nonvolatile by-products generated when the opening such as a via hole is formed, are completely removed.

Abstract: A method for interconnecting layers in a semiconductor device is disclosed. The device includes a lower conductive layer formed by capping a second conductive layer on a first conductive layer, a contact window formed in an inter-insulating layer on the lower conductive layer, and an upper conductive layer connected to the lower conductive layer through the contact window. The contact window is formed by removing a portion of the inter-insulating layer where the contact will be formed using a first etching gas, and removing a portion of the second conductive layer where the contact will be formed using a second etching gas. The contact resistance becomes uniform by preventing the formation of a non-volatile mixture in the contact window, and the reliability of the device is improved by planarizing the surface of the lower conductive layer.
