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.

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: 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.

Abstract: A fieldless CMOS image sensor that include a non-LOCOS isolation structure surrounding the photodiode diffusion region of each pixel. The isolation structure is formed by an anti-punchthrough (APT) implant isolation region formed in the substrate around the photodiode diffusion region, and spacer oxide that is formed using a special mask to cover the APT implant region. 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.

Abstract: A bumped semiconductor device contact structure is disclosed including at least one non-planar contact pad having a plurality of projections extending therefrom for contacting at least one solder ball of a bumped integrated circuit (IC) device, such as a bumped die and a bumped packaged IC device. The projections are arranged to make electrical contact with the solder balls of a bumped IC device without substantially deforming the solder ball. Accordingly, reflow of solder balls to reform the solder balls is not necessary with the contact pad of the present invention. Such a contact pad may be provided on various testing equipment such as probes and the like and may be used for both temporary and permanent connections. Also disclosed is an improved method of forming the contact pads by etching and deposition.

Abstract: An integrated circuit has a multi-layer stack such as a gate stack or a digit line stack disposed on a layer comprising silicon. A conductive film is formed on the transition metal boride layer. A process for fabricating such devices can include forming the conductive film using a vapor deposition process with a reaction gas comprising fluorine. In the case of a gate stack, the transition metal boride layer can help reduce or eliminate the diffusion of fluorine atoms from the conductive film into a gate dielectric layer. Similarly, in the case of digit line stacks as well as gate stacks, the transition metal boride layer can reduce the diffusion of silicon from the polysilicon layer into the conductive film to help maintain a low resistance for the conductive film.

Abstract: A square poly-spacer and making of the same are disclosed. The square poly-spacer is formed adjacent a floating poly-gate sharing a common source line with another floating poly-gate. The common source line comprises polysilicon and is separated from the floating poly-gate by an intervening oxide spacer. The square poly-spacer is also separated from the floating gate by an intergate oxide layer, and serves as a control gate and communicates with a salicided word line formed over the square top of the poly-spacer. It is shown that a square poly-spacer can be formed advantageously by first chemical mechanical polishing a poly spacer and then performing an etch back of the polysilicon, rather than just performing an etch back only. The square top, rather than the continuously contoured sloping wall, prevents the bridging that can occur over a curved poly spacer to the substrate when a portion of the poly spacer surface is salicided to obtain a well behaving word line.

Abstract: A method of forming an oxide layer on a substrate comprises deposition of a mask layer with an opening for defining the area where the oxide layer is to be formed, and an ion implantation step performed with a tilt angle so as to obtain a varying ion concentration. In a subsequent single oxidation step, an oxide layer is formed having a thickness that varies in conformity with the ion concentration. This method may advantageously be applied to the formation of a gate insulation layer in a field effect transistor.

Abstract: A unique electrochemical process fills oxygen vacancies in dielectrics while reducing oxidation of nearby electrodes and conductors. Preferably, an electromagnetic field or bias is applied to a dielectric. The bias causes oxygen vacancies in the dielectric to migrate to the surface of the dielectric. As the oxygen vacancies migrate toward the surface, oxygen ions fill the oxygen vacancies. In one embodiment, a unique plasma treatment provides the oxygen ions that react with the oxygen vacancies. In another embodiment, a unique electrolysis treatment provides the oxygen ions that react with the oxygen vacancies.

Characteristics of the semiconductor device are obtained according to the impurity concentration distribution. This method reduces the period of time to calculate the characteristics of the semiconductor device.
