Semiconductor/Solid-State Device Manufacturing TRIZ Cases

An aqueous nitric-phosphoric etchant speeds tungsten and TiN recess while limiting aluminum oxide damage in 3D NAND processing.

Plasma surface treatment removes impurities and neutralizes charge on amorphous silicon, improving photoresist adhesion and pattern transfer accuracy.

Backside crack formation cleaves semiconductor wafers while keeping residual stress away from element structures to reduce chipping and reliability loss.

Pressure-equalized sealed substrate carriers protect wafers from particulates and reactive gases during transport and tool docking.

A lift-off patterned aluminum oxide hard mask resists erosion in deep reactive ion etching, preserving high-resolution feature dimensions.

Partial wafer loading from a heated multi-slot retainer cuts chamber temperature loss and shortens semiconductor processing time.

Two patterned mask layers jointly define smaller etch openings, pushing DRAM feature scaling past photolithography resolution limits.

An As-containing epitaxial barrier blocks P diffusion into the channel and limits out-gassing during metallization in FinFET source/drain regions.

Using silahydrocarbon precursors, this case shows stoichiometric SiC film growth with low hydrogen and no post-deposition annealing.

A slow-diffusing implanted capping layer contains phosphorus up-diffusion in vertical MOSFET epitaxy, lowering Rds(on) and stabilizing dopant profiles.

Gradual stress-transition films flatten bowed substrates with sloped interfaces, improving photolithography overlay accuracy and reducing yield loss.

Epitaxial collector and emitter links to the substrate create thermal exit paths that cut self-heating and support higher fT/fmax in lateral HBTs.

Rapid thermal oxidation forms a fully oxidized gate oxide layer that improves ROX scalability, breakdown voltage, and hot-carrier reliability.

Narrow, segmented support pillars with spigot positioning reduce film thinning near columns while preserving substrate support strength.

Sidewall insulation covers exposed high-k dummy pattern edges at isolation steps, preventing detachment and re-adhesion during semiconductor processing.

Selective oxygen implantation enables low-temperature p-type activation, avoids etching loss, cuts leakage current, and raises breakdown voltage.

A rear trench and laser-formed reformed portion guide uniform crack propagation, reducing chipping, surplus material, and split-chip defects.

Laser-formed modification layers enable cleaner stacked substrate thinning after bonding, cutting energy use and avoiding radioactive shielding.

A halosilane and ammonia or hydrazine cycle enables selective silicon nitride growth on target surfaces while preserving etch resistance without plasma.

Gas blown at the substrate underside before chamber entry removes residual liquid, shortening supercritical processing and reducing defects.

A material-layer etch mask splits photoresist patterns into sub-patterns, increasing template density while pushing line widths below 100 nm.

Cyclic carbon deposition, oxygen surface modification, and B/Si/Al passivation suppress sidewall bowing in high-aspect-ratio dielectric etching.

Embedding nickel during silicon carbide grinding and then laser annealing forms low-resistance ohmic contacts with fewer process steps.

Wider hard masks on LNA metal gates expand gate area to cut noise figure and gate-to-body capacitance in high-k transistor fabrication.

Masked dual-trench interconnect formation limits over-etching and short-circuit risk while preserving dense semiconductor routing.

A planar inner heater and coil outer heater share one ceramic plate to reduce inner-zone temperature variance and keep wafer heating uniform.

A zinc precursor and thermal soak form a self-forming barrier at the liner-dielectric interface, improving adhesion and lowering interconnect resistivity.

Deformable films and incompressible fluid apply uniform pressure and temperature control for stable multi-substrate semiconductor bonding.

Raised epitaxial source and drain regions plus a nitride-covered drain extension cut electric field and improve SOI high-voltage breakdown.
