SEMICONDUCTOR TECHNOLOGY

Semiconductor Technology

HBM, advanced packaging, AI inference architecture, and the system-level tradeoffs behind modern chips.

AI Comic Classroom #1: LLM Tokens and KV Cache

A six-page classroom that starts with a simple question: how does an LLM keep writing one piece at a time? We begin with next-token prediction, then move into tokens, vectors, K/V notes, KV Cache, and the memory cost that appears when conversations get long.

HBM Classroom 2: Base Die and Repair Evolution

A six-page classroom on the base die at the bottom of an HBM stack. It explains why the base die is more than wiring, how traditional DRAM repair changes in a 3D stack, and why repair can protect the value of the whole AI package.

Semiconductor Packaging Classroom: From CoWoS to ABF

A seven-page classroom on advanced packaging as the work of moving chips closer together. It compares CoWoS, silicon interposers, CoPoS, ABF substrates, and PCBs by the distance, density, bandwidth, and yield problems they solve.
