摘要:
A simple method for diminishing the trench width in a photoresist structure to below the resolution limit is provided. A photoresist structure is produced and treated with an agent then contains a bulging constituent that reacts with functional groups of the photoresist structure. The bulging constituent causes a volume increase of the photoresist structure. The extent of the volume increase of the photoresist structures is controllable by varying various parameters.

A semiconductor device includes a semiconductor chip and a metal layer electrically coupled to the semiconductor chip. The semiconductor device includes an array of solder balls coupled to the metal layer and a front side protect material directly contacting the metal layer and laterally surrounding a portion of at least a plurality of solder balls. The front side protect material is configured to become fluid during solder reflow.

A semiconductor device including a chip including an integrated circuit, a conductive layer, a copolymer layer and metal elements. The conductive layer is disposed over the chip and electrically coupled to the integrated circuit. The copolymer is disposed on the conductive layer. The metal elements are electrically coupled to the conductive layer via through-connects in the copolymer layer.

High-temperature-stable polybenzoxazoles are formed from novel poly-o-hydroxyamides. The novel poly-o-hydroxyamides have low dielectric constants, are suitable for exposure at 248 nm or shorter wavelengths, and have hydroxyl groups at least some of which have been protected by tert-butoxycarbonyl protective groups.

The invention relates to a component having two adjacent insulating layers and to a production process therefore. The component has an activated insulating layer, which can be converted into an electrically conductive layer by metallization.
摘要:
A photosensitive formulation for high-temperature-resistant photoresists is based on polyhydroxyamides. The photosensitive formulations display a much higher photosensitivity than the comparable formulations based on quinone azide photoactive components. After conversion to the polybenzoxazole, the novel formulations also display a lower dielectric constant than the quinone azide-based formulations. A film can be made by applying the photosensitive formulation to a wafer and then evaporating the solvent. A method for fabricating electronics and micorelectronics structures a wafer by using the film in photolithography.
摘要:
There are disclosed polybenzoxazole precursors which can be processed by centrifugal techniques, which can be cyclized to polybenzoxazoles on substrates without difficulty, and which after cyclization to polybenzoxazoles exhibit a high temperature stability. In particular, these precursors and the polybenzoxazoles prepared from them possess high resistance against the diffusion of metals.

The invention relates to novel o-aminophenolcarboxylic acids or o-aminothiophenolcarboxylic acids of the following structure in which: A1 to A7 are—independently of one another—H, CH3, OCH3, CH2CH3 or OCH2CH3; T is O or S, and m is 0 or 1; Z is a carbocyclic or heterocyclic aromatic radical.
摘要:
In a process for the preparation of poly-o-hydroxyamides and poly-o-mercaptoamides, a bis-o-aminophenol or a bis-o-aminothiophenol is reacted with a dicarboxylic acid derivative with the following structure: ##STR1## where D=O, S, or NH, and where R* is the parent body of the dicarboxylic acid and at least one of the groups R.sup.1 through R.sup.5 is F or CF.sub.3.
摘要:
In a process for the preparation of poly-o-hydroxyamides and poly-o-mercaptoamides, a bis-o-aminophenol or a bis-o-aminothiophenol is reacted with a dicarboxylic acid derivative with the following structure: M--CO--R*--CO--M where M stands for the residue of an (optionally substituted) 2-hydroxybenzoxazole, 2-hydroxybenzothiazole, or 1-hydroxybenzotriazole or of corresponding mercapto compounds and R* is the parent body of the dicarboxylic acid.
