The Semiconductor Environment - Part 6

Explore advanced topics in semiconductor materials and technologies, building on fundamentals, business models, production basics, and career opportunities from parts one through five.

Explore Moore's law and transistor counts, from the first transistor to 16 billion on today's chips. See how flops measure performance across Apollo, NES, iPhone 4, and Xbox.

Explore how increasing transistor density and multifactor improvements, such as thinner memory dies, smaller transistors, and packaging advances, drive semiconductor device performance while managing heat and power.

EUV lithography uses 13.5 nanometer light generated by tin plasma and a mirror-based optical system to project patterns onto wafers, enabling single mask patterns down to the two nanometer scale.

The lecture explains advanced grinding to thin wafers with Tycho, enabling higher transistor counts by stacking dice, while addressing bow and warp, handling challenges, and EUV lithography limits.

Reversing the usual flow, the dbg process half-cuts first and then grinds, reducing backside chipping and blade-induced damage to improve die quality.

Apply stealth dicing, a non-abrasive laser technique that weakens silicon at the focus to form a braking area, enabling wafer separation with xy expander guided stress and minimal chipping.

Explore silicon carbide as a material enabling higher breakdown field, wider band gap, and better thermal conductivity for higher voltage, thinner, lower loss power devices, with processing and supply challenges.

Explore the evolution of semiconductor packaging, from the dual in-line package to surface mount technologies, quad flat packages, and ball grid arrays, highlighting connections, protection, heat dissipation, and reliability.

Explore how SoC unifies CPU, GPU, connectivity, and periphery to boost performance while prioritizing power usage, efficiency, low heat, and minimal latency, moving beyond traditional separate chips.

Explore system in package (sip) and flip-chip technology, the most advanced packaging today, enabling flexible, high-performance connections as Moore's Law slows and interposers, 2.5D packaging, and 3D packaging are leveraged.

Explore the interposer, a layer between the substrate and dies that uses tsv, redistribution layers (rdl), ubm, and solder bumps to connect dies and enable compact, efficient signal paths.

Explore 2.5D and 3D packaging as system in package approaches, linking or stacking dies on a silicon interposer to boost performance and transistor density, with active interposers as an option.

Wafer level packaging offers two approaches: fan-out and traditional wafer-level packaging, using RDL layers, solder balls, and molded or unmolded options to protect dies before singulation.

Discover how high bandwidth memory (HBM) boosts bandwidth and reduces power and latency for AI and graphics, enabled by 2.5D/3D packaging with TSVs and stacked memory dies.

Explore how every aspect of semiconductors: design, materials, processes, machines, and packaging evolves. Packaging advances, materials like silicon carbide and gallium nitride, and collaboration boost density, switching speeds, and reliability.
