    摘要: A method and apparatus is provided for planarizing damascene metallic circuit patterns of a plurality of discrete integrated circuit chips on a metal coated silicon wafer wherein the circuitry on the chips on the wafer are either designed to be within a defined high metal density circuit range and low density metal circuit range and/or to provide dummy circuitry in the damascene process to provide a substantially uniform circuit density over the chip and the wafer surface. It is preferred that each chip on the surface of the wafer be divided into a plurality of regions and that each region be provided with dummy metallization, if necessary, to provide a relatively uniform circuit density in that region and consequently on the wafer surface. The invention also contemplates adding dummy circuitry to the periphery of the wafer in areas which are not formed into chips (chip fragments). The invention also provides semiconductor wafers made using the method and/or apparatus of the invention.

    摘要: Selective placement of polishing dummy feature patterns, rather than indiscriminate placement of polishing dummy feature patterns, is used. Both low frequency (hundreds of microns and larger) and high frequency (10 microns and less) of topography changes are examined. The polishing dummy feature patterns can be specifically tailored to a semiconductor device and polishing conditions used in forming the semiconductor device. When designing an integrated circuit, polishing effects for the active features can be predicted. After polishing dummy feature pattern(s) are placed into the layout, the planarity can be examined on a local level (a portion but not all of the device) and a more global level (all of the device, devices corresponding to a reticle field, or even an entire wafer).

    摘要: A method for forming a MOSFET (200) using a disposable gate. A disposable gate (220) having at least two materials that may be etched selectively with respect to each other is formed on a substrate (202). A sidewall dielectric (215) is formed on the sidewalls of the disposable gate (220). The composition of the disposable gate materials (222, 223 and 224) and the sidewall dielectric (215) are chosen such that the disposable gate (220) may be removed selectively with respect to the sidewall dielectric (215). A dielectric layer (214) is then deposited over the structure and a portion of the dielectric layer (214) is removed to expose the disposable gate (220) (e.g. using CMP or an etch-back). The composition of the dielectric layer (214) is chosen such that (1) the dielectric layer (214) may be removed selectively with respect to the sidewall dielectric (215) and (2) a layer of the disposable gate (220) may be removed selectively with respect to the dielectric layer (214). The disposable gate (220) is then removed and the gate dielectric (210) and gate electrode (212) are formed.

    摘要: A method for controlling the spacing between the emitter mesa and the base ohmic metal of a heterojunction bipolar transistor (HBT) to obtain a relatively high gain (β) with a low-parasitic base resistance. In a first method, after the emitter, base and collector layers are epitaxially grown on a substrate, a sacrificial layer is deposited on top of the emitter layer. The emitter mesa is patterned with a photoresist using conventional lithography. Subsequently, the sacrificial layer is etched to produce an undercut. The emitter layer is then etched and a photoresist is applied over the first photoresist used to pattern the emitter mesa, as well as the entire device. The top layer of photoresist is patterned with a conventional process for lift-off metalization, such that the final resist profile has a re-entrant slope. The base ohmic metal is deposited and then lifted off by dissolving both the second layer of photoresist, as well as the original photoresist over the emitter mesa. The sacrificial layer is stripped using an isotropic etch leaving a base ohmic metal region surrounding an emitter mesa at a spacing that is determined by the initial undercut of the sacrificial layer. In an alternate embodiment of the invention, a method is disclosed for controlling the spacing between the base ohmic metal and an emitter ohmic metal.

    摘要: A fuse link 16 is formed of a portion of a top level of patterned metal conductor in a multilevel conductor integrated circuit 10. A deposited layer of oxide material 26 covers the fuse link. Radiant energy from such as a laser 36 is directed through the oxide material 26 to heat and open the fuse link 16. Layers of deposited protective oxide 28 and PIX 30 then cover the fuse link and layer of oxide material. One photoprocessing step is avoided by locating the fuse link 16 and bond pad 22, both made from the top layer of conductive material, at different levels. The blanket etch then exposes the bond pad 22 while leaving the fuse link 16 covered. The fuse link can be formed down in a step 38 or the bond pad 22 can be formed above such as a group of memory cells 80. The bond pad 22 and fuse link 16 also can be formed at the same level with other process procedures.
