    摘要: Interconnect structures possessing an organosilicate glass based material for 90 nm and beyond BEOL technologies in which a multilayer hardmask using a line-first approach are described. The interconnect structure of the invention achieves respective improved device/interconnect performance and affords a substantial dual damascene process window owing to the non-exposure of the OSG material to resist removal plasmas and because of the alternating inorganic/organic multilayer hardmask stack. The latter feature implies that for every inorganic layer that is being etched during a specific etch step, the corresponding pattern transfer layer in the field is organic and vice-versa.

    摘要: An interconnect structure including a patterned multilayer of spun-on dielectrics as well as methods for manufacturing the same are provided. The interconnect structure includes a patterned multilayer of spun-on dielectrics formed on a surface of a substrate. The patterned multilayer of spun-on dielectrics is composed of a bottom low-k dielectric, a buried etch stop layer, and a top low-k dielectric, wherein the bottom and top low-k dielectrics have a first composition, the said buried etch stop layer has a second composition which is different from the first composition and the buried etch stop layer is covalently bonded to said top and bottom low-k dielectrics. The interconnect structure further includes a polish stop layer formed on the patterned multilayer of spun-on dielectrics; and metal conductive regions formed within the patterned multilayer of spun-on dielectrics. Covalent bonding is achieved by employing an organosilane having functional groups that are capable of bonding with the top and bottom dielectric layers.

    摘要: The present invention describes the use of large thin film (TF) capacitors having capacitance C made in a separate set of TF layers ABOVE the Si and wiring levels of an integrated circuit (IC). This C is very large. This invention describes a two-level IC architecture in which a metal/insulator/metal (MIM) capacitor structure comprises the upper level, and CMOS logic and memory circuits made in the Si wafer substrate comprise the lower level. The added thin film capacitance serves to stabilize the power supply voltage at a constant level during GHz IC operation.

    摘要: A thin film transistor is described incorporating a gate electrode, a gate insulating layer, a semiconducting channel layer deposited on top of the gate insulating layer, an insulating encapsulation layer positioned on the channel layer, a source electrode, a drain electrode and a contact layer beneath each of the source and drain electrodes and in contact with at least the channel layer, all of which are situated on a plastic substrate. By enabling the use of plastics having low glass transition temperatures as substrates, the thin film transistors may be used in large area electronics such as information displays and light sensitive arrays for imaging which are flexible, lighter in weight and more impact resistant than displays fabricated on traditional glass substrates. The thin film transistors are useful in active matrix liquid crystal displays where the plastic substrates are transparent in the visible spectrum. Enablement of the use of such plastics is by way of the use of polymeric encapsulation films to coat the surfaces of the plastic substrates prior to subsequent processing and the use of novel low temperature processes for the deposition of thin film transistor structures.
