Abstract: Embodiments are disclosed for semiconductor manufacturing using disposable test circuitry formed within scribe lanes. The manufacturing steps can include forming device circuitry within a semiconductor die and forming test circuitry within a scribe lane. One or more electrical connection route lines are also formed that connect the device circuitry and test circuitry blocks. Further, each die can be connected to a single test circuitry block, or multiple dice can share common test circuitry blocks. After testing, the electrical connection route line(s) are sealed, and the test circuitry is discarded when the device dice are singulated. For certain embodiments, the edge of the devices dice are encapsulated with a protective metal layer, and certain other embodiments include protective sealrings through which the connection route lines pass to enter the dice from the test circuitry blocks within the scribe lanes.

Abstract: A method for forming an integrated circuit involves forming trench isolation regions (208a) and a damascene gate electrode region (214) simultaneous with one another via overlapping process steps. By performing this simultaneous formation of a trench region (208a) and a damascene gate electrode (214) using a common dielectric layer (208), MOS integrated circuits can be formed with reduced processing steps while simultaneously avoiding adverse polysilicon stringers which are present in prior art damacene-formed gate electrode. A single dielectric layer (208) is deposited in order to provide trench fill material for a trench region (208a) while simultaneously providing the material needed for form an opening (210) which is used to define the dimensions and material content of a gate electrode (214).

Abstract: In one embodiment a non-volatile memory device having improved reliability is formed by oxidizing a first portion of a semiconductor substrate (12) to form a first silicon dioxide layer (14). The first silicon dioxide layer (14) is then annealed and second portion of the silicon substrate, underlying the annealed silicon dioxide layer (16), is then oxidized to form a second silicon dioxide layer (18). The annealed silicon dioxide layer (16) and the second silicon dioxide layer (18) form a pre-oxide layer (20). The pre-oxide layer (20) is then nitrided to form a nitrided oxide dielectric layer (22). A floating gate is then formed overlying the nitrided oxide dielectric layer (22), which serves as the tunnel oxide for the device. Tunnel oxides formed with the inventive process are less susceptible to stress-induced leakage, and therefore, devices with improved data retention and endurance may be fabricated.

Abstract: A stack of oxide (16) and silicon nitride (18) is grown/deposited over a patterned polysilicon line, which typically acts as a bottom capacitor plate. A thin layer of amorphous or polycrystalline silicon (20) is deposited over the blanket silicon nitride film. The thickness of the deposited silicon layer must be optimized according to the final amount of oxide desired over the silicon nitride, which will be roughly twice the thickness of the deposited silicon film. The oxide/nitride/silicon stack is then patterned and etched, stopping either at or underneath the bottom oxide. Any subsequent cleaning in potentially oxide-etching chemistries (including HF) is done with the protective silicon deposit on top of the silicon nitride. The entire structure is then thermally oxidized, transforming the deposited silicon into silicon oxide (30). Where the structure has been cleared down to the substrate by etching, a second gate oxide is simultaneously formed.

Abstract: A method for forming an air region or an air bridge overlying a base layer (12). Air regions (20a, 20b, 28a, and 48) are formed overlying the base layer (12) to provide for improved dielectric isolation of adjacent conductive layers, provide air-isolated conductive interconnects, and/or form many other microstructures or microdevices. The air regions (20a, 20b, 28a, and 48) are formed by either selectively removing a sacrificial spacer (16a and 16b) or by selectively removing a sacrificial layer (28, 40). The air regions (20a, 20b, 28a, and 48) are sealed, enclosed, or isolated by either a selective growth process or by a non-conformal deposition technique. The air regions (20a, 20b, 28a, and 48) may be formed under any pressure, gas concentration, or processing condition (i.e. temperature, etc.). The air regions (20a, 20b, 28a, and 48) may be formed at any level within an integrated circuit.
