Abstract: A process of forming fine repetitive geometries using a mask having large mask dimensions. The pitch of the masking pattern on the mask is divided by the process to obtain a smaller pitch in the fine repetitive geometries. At least two working materials are used one of which can be etched without etching a substrate. In one embodiment the two working materials and the substrate are each etched independently. In other embodiments, the substrate and one working material have similar etch rates while the other material is etched independently. Pedestals are formed having an initial pitch. First sidewalls are formed around the pedestals. The pedestals are removed and a second and third sidewall are formed on the inside and outside surfaces of the first sidewall having spaces there-between. The first sidewall is removed generating another space between the second and third sidewall.

Abstract: A method and an apparatus for growing a layer on one surface of a wafer by liquid phase deposition are provided. At first, a first wafer is putted on a first wafer-holder by its first surface. Then, a growth-liquid vessel having a first opening at the bottom is mounted on the first wafer-holder. Thereafter, a growth liquid is poured into the growth-liquid vessel to expose a second surface of the first wafer to the growth liquid for growing the layer on the second surface of the first wafer. Then, the, first wafer is taken out from the first wafer-holder to obtain a wafer with a layer grown only on one surface.

Abstract: A plasma photoresist hardening technique is provided to improve the etch resistance of a photoresist mask 26. The technique involves the formation of a thin passivation layer 26b on the photoresist mask 26 which substantially slows down the etching rate of the photoresist material 26a. Advantageously, this technique allows preservation of critical dimension features such as via hole openings and transmission lines. The technique hardens the surface of the photoresist film 26 by both chemically and physically bonding halogenated hydrocarbons with cross linked photoresist polymer. This results in a passivation layer 26b which is highly resistant to harsh plasma etch environments.

The self-test controller is associated with a memory array that includes a clock having a clock speed. The memory array also includes a clock adjuster that receives the interface signal and reduces the clock speed when the interface signal indicates that a DVS test is being performed.

Abstract: Methods of forming integrated circuit devices (e.g., memory devices) include the use of preferred self-aligned contact hole fabrication steps. These steps improve process reliability by reducing the likelihood that contact holes will become misaligned to underlying integrated circuit device structures and thereby potentially expose the structures in an adverse manner. Typical methods include the steps of forming a plurality of interconnection patterns on a substrate and then covering a surface of the interconnection patterns and a portion of the substrate with a capping insulating layer such as silicon nitride layer. The capping insulating layer is then covered with an upper interlayer insulating layer different from the capping insulating layer. The upper interlayer insulating layer and the capping insulating layer are then dry-etched in sequence to form a first narrow contact hole that exposes the substrate, but preferably does not expose the interconnection patterns.

Abstract: A component for fabricating microelectronic assemblies has numerous curved leads on a surface. Each lead has a first anchor end fixed to the body of the component, a second tip end which can be bonded to a contact on a mating component and lifted away from the component body, and an elongated main portion which is bent away from the component body in the lifting action. The first anchor end of each lead is nested within the curved portion of another lead, so as to provide an extraordinarily compact arrangement suitable for use with components having closely spaced contacts as, for example, a semiconductor chip or wafer having a contact pitch less than 500 microns. The leads may be disposed in pairs, with the first anchor end of each lead encompassed by the main portion of the other lead in the same pair.

Following an implantation step using the mask layer as an implantation mask, the etch-back exposes implant damage which is then annealed by an energy beam (42).

Abstract: The invention relates to a process for treating semiconductor substrates in which metal layers are exposed by removing one or more layers of the surface of a semiconductor substrate which have been applied to the metal layer, in which exposure takes place in a time sequence to a first part of the layer by a dry etching step and to a second part of the layer by a wet etching step.

Abstract: The compilation of a high-level software-based description of an algorithm into efficient digital hardware implementation(s) is addressed. This is done through the definition of new semantics for software constructs with respect to hardware implementations. This approach allows a designer to work at a high level of abstraction, while the semantic model can be used to infer the resulting hardware implementation. These semantics are interpreted through the use of a compilation tool that analyzes the software description to generate a control and data flow graph. This graph is then the intermediate format used for optimizations, transformations and annotations. The resulting graph is then translated to either a register transfer level or a netlist-level description of the hardware implementation.

Abstract: First, a pattern of electrodes or interconnects is formed on a semiconductor substrate. Next, a first insulating film, which will be dry-etched at a relatively high rate and exhibit relatively high planarity, is deposited over the substrate as well as over the pattern. Subsequently, a second insulating film, which will be dry-etched at a relatively low rate and exhibit relatively low planarity, is deposited over the first insulating film. Thereafter, a multilayer structure, including a ferroelectric film, is formed on the second insulating film and then dry-etched and patterned, thereby forming an electronic device out of the multilayer structure.

Abstract: A semiconductor device assembly and a semiconductor device are provided which both can ensure reliability after a mounting process. The semiconductor device includes a semiconductor element equipped with bumps on an electrode patterned surface thereof for external connection. In the semiconductor device mounted on a substrate in the semiconductor device assembly, a semiconductor element shaped to have a thickness ranging from 200 &mgr;m to 10 &mgr;m has reduced flexural rigidity so as to be easily deflected. In the status that the bumps are joined to corresponding circuitry electrodes on the substrate, the semiconductor element can deflect at other portions other than its surface between two adjacent bumps according to contraction and distortion of the substrate. This allows the bumps to be dislocated in a direction parallel to a surface of the semiconductor element, hence relieving stress developed by the contraction of the substrate at the joint positions between the bumps and the circuitry electrodes.

The APT implant isolation region is self-aligned with the special spacer oxide mask. A width of the isolation structure between two adjacent photodiodes is 0.5 &mgr;m or more. Similarly, LOCOS structures that are used, for example, in the image sensor active circuitry, are separated from the image-sensing (e.g., photodiode) region of each pixel by portions of the isolation structure having a width of 0.5 &mgr;m or more.
