    摘要: A semiconductor circuit package includes features forming an electrostatic charge distribution network having nodes which are defined by the electrical contact leads of the package for the semiconductor circuit, and which are effectively connected with one another by spark-gaps. In one embodiment electrical leads of the package are provided with pointed protrusions lying in the plane of the electrical leads. Accordingly, an inadvertent electrostatic discharge is distributed throughout the semiconductor circuit at safe voltage levels determined by the characteristics of the spark gaps of the charge distribution network.

    摘要: Various techniques of forming isolation structures between adjacent diffusion regions are disclosed. In one technique, a thermally-grown oxide isolation structure is gouged out, and subsequent poly extending into the gouged out isolation structure is substantially level with the diffusion region. In another technique, a trench (bathtub) is formed, lightly oxidized, overfilled with polysilicon or amorphous silicon, gouged out, and thermally treated to form a substantially planar isolation structure. In another technique, an isolation structure exhibiting bird's-heads and bird's-beaks is polished until the bird's-beaks are removed. Gouging of the diffusion area may be permitted to occur. A bipolar transistor structure can be formed in the gouged diffusion area, and will exhibit reduced spacing between the intrinsic base and collector without proportionally reduced spacing between the extrinsic base and the collector.

    摘要: The surface of an optical element, such as the taking lens in semiconductor photolithographic apparatus, is deformed, in situ, by applying heat to the surface. A recipe for applying the heat to a selected area of the lens surface is developed by either measuring the image projected by the lens and comparing the measured image to the specified (mask) image, or by measuring the contour of the surface of the lens and comparing the measured contour to the lens' specified contour. The heat is applied by a laser, the output of which is focussed and scanned onto the surface of the lens. Method and apparatus are disclosed.

    摘要: A preformed planar structure is interposed between the chip(s) and the substrate in a flip-chip structure, and establishes a minimum gap between the chip(s) and the substrate. Liquid flux may be applied to the preformed planar structure in order that flux is selectively applied to the solder balls (pads) on the chip and the substrate. The preformed planar structure may be provided with through holes in registration with the solder balls on the chip(s) and the substrate. In this case, liquid flux selectively fills the through holes for delivery to the solder balls during soldering. The through holes also aid in maintaining registration of the chip(s) and the substrate. The through holes may be sized to establish a predetermined mechanical structure of solder joints formed by the solder balls when fused together. The preformed planar structure has a planar core and opposing planar faces. The core is formed of thermosetting organic resin, such as polyimide, or non-organic material such as alumina, polished sapphire, beryllium oxide, aluminum nitride or aluminum. The planar faces of the preformed planar structure are formed of thermoplastic resin or thermosetting material, such as polyacetal, epoxide resin or polystyrene. The preformed planar structure tends to draw the chip(s) together to the substrate, establishing a flip-chip structure of mechanical integrity. The preformed planar structure has a thickness of 5-50 microns, preferably on the order of 20-30 microns. Method and apparatus are disclosed.

    摘要: A structure is formed on an electronic integrated circuit by altering the electrical characteristics of a diffused region of a substrate through a contact hole (window) in an insulating layer, in proportion to the size of said contact hole, such that the resistance of the diffused region is changed in a known and predictable fashion and may be measured electrically, giving indirect but accurate evidence of contact size in a completely nondestructive fashion. The measurements may be made on completed devices. Method and structure are disclosed.

    摘要: An integrated circuit structure is provided with a local interconnect layer and a first metal interconnect layer which are both capable of bridging over underlying conductive regions. The structure comprises a first dielectric layer formed to a height or thickness equal to or preferably exceeding the height of the highest conductive regions of the underlying integrated circuit devices; a second dielectric layer formed above the first dielectric layer; one or more local interconnects formed in the second dielectric layer; and a thin third dielectric layer formed over the second dielectric layer and the local interconnects therein. The thin third dielectric layer has a thickness not exceeding about 2000 Å, and preferably ranging from about 1000 Å to about 1500 Å. A first layer of metal interconnects is formed over the thin third dielectric layer. Conventionally formed filled contact openings extend from the substrate through the first dielectric layer to either filled vias or a local interconnect in the second dielectric layer. The metal interconnects are electrically connected to either filled vias or one or more local interconnects in the second dielectric layer by filled shallow vias in the thin third dielectric layer. The shallow vias in the thin third dielectric layer are preferably filled with the same metals used to form the first layer of metal interconnects.

    摘要: Described is an improvement in a process wherein integrated circuit structures are formed on a front surface of a silicon substrate and at least one layer of copper is deposited on the front surface of the substrate to form a layer of copper interconnects, and wherein at least some copper is also deposited on the back surface of the substrate during this deposition. The improvement comprises: prior to the end of the formation of the integrated circuit structures, abrasively removing, from the backside of the substrate, copper deposited thereon during the deposition of copper on the front surface. The step of abrasively removing copper from the back side of the substrate is preferably carried out before exposure of the substrate and the copper thereon, including copper deposited on the back side of the substrate, to any subsequent high temperature processing, and preferably, the step of abrasively removing the copper from the backside of the substrate comprises a chemical/mechanical polishing step which leaves a polished surface on the backside of the substrate to facilitate subsequent mounting or packaging of the integrated circuit structures.
