Semiconductor/Solid-State Device Details TRIZ Cases

An ALD dielectric over chip passivation and contact pads blocks moisture and mobile ions, improving HTRB stability in molded packages.

An outwardly curved resin cover secures the light transmissive component against removal while maintaining luminance and reducing glare.

A dual-boiling-point solvent resin composition improves step embedding on narrow coil patterns, keeping insulation films flat during drying and curing.

A conductive metal pillar bridges the FET chip and mother board to improve heat dissipation, cut source inductance, and protect amplifier gain.

Combining ALD with CVD or PVD forms NAND conductive interconnects with lower tensile stress while balancing deposition speed and cost.

Varying-pitch conductive layers and a matched interposer reduce wafer warpage and package thickness in stacked semiconductor packaging.

Non-circular landing pads and dummy TSVs improve etch uniformity, raise routing density, and reduce epoxy void risk in 3D IC stacks.

A shaped insulating pattern prevents pad dimpling, preserves pad-via design freedom, and improves package electrical and mechanical reliability.

A low-resistance metal common-node connection links split power transistor dies to cut switching and conduction losses while improving reliability.

Grouped ground vias in package substrates suppress crosstalk in high-speed single-ended channels without increasing package size or pin count.

A thin film substrate uses a local reinforcement member around the chip to limit warping, reduce wiring cracks, and improve mounting alignment.

A thicker local insulator and shared BEOL vias integrate thin film resistors with memory while reducing etch misalignment and copper diffusion.

Selective masking lets mold material protect IC package elements while keeping I/O pads exposed on multiple sides for flexible layout.

Air gaps under dielectric regions between dense metal plugs cut parasitic capacitance, reducing semiconductor power loss and signal delay.

A three-step re-etching sequence cuts RDL undercuts in InFO packaging, improving fine-pitch reliability and enabling higher I/O pad density.

Processing IC dies on a dicing sheet enables in-place cleaning, plasma activation, and low-contamination transfer for more reliable bonding.

A localized pressure differential steers bond wave propagation to expel trapped air and reduce wafer bonding voids and edge defects.

Conductive walls and a cap create wafer-level EMI shielding in fan-out packages without costly copper lids or embedded shields.

Embedding grounded Faraday-shielded voltage regulators in the substrate cuts processor power-delivery distance, reducing EMI, losses, and footprint.

Direct hybrid bonding and precise singulation shrink edge exclusion zones, enabling tighter die spacing, higher I/O density, and lower interconnect latency.

Coordinated positioning and grounding before parallel pressurizing prevents stage bending from shifting chip alignment during bonding.

Selective Ni plating blocks solder diffusion into the brazing layer, improving furnace resistance and heat-cycle crack durability.

A split multi-voltage power bus layout cuts top metal track use and lowers voltage drop in compact IC load-circuit routing.

Flux or underfill temporarily holds multiple LED dies for one heating cycle, reducing oxide formation, misalignment, and bonding damage.
