7.1 DRの基本思想と構造

7.1 Fundamentals and Structure of Design Review (DR)


🎯 本節のねらい|Purpose of This Section

本節では、半導体製品開発における
技術レビュー(Design Review: DR)の基本思想と構造的役割を解説する。

This section explains the fundamental philosophy and structural role of Design Review (DR) in semiconductor product development.

DRは単なる会議ではなく、各フェーズにおける技術的妥当性の合意形成プロセスである。

DR is not just a meeting, but a process to establish technical consensus at each development phase.


🧱 DRの目的と意義|Objectives and Significance of DR

🇯🇵 目的 🇺🇸 Objective 内容/意義
技術妥当性の検証 Technical Validation 設計・プロセスが仕様・信頼性・量産性に合致するか確認
合意形成と責任共有 Cross-Departmental Consensus 多部門でのリスク共有と対応力の強化
節目確認と判断材料化 Milestone Checkpoint フェーズごとの進捗と技術課題を整理し、次工程の判断根拠とする

🔁 DRの3段階構造(代表例)

🔁 Three-Stage Structure of DR (Typical Example)

① 企画DR(Concept / Planning Review)

Clarifies product requirements and specifications with broad departmental input.
Focus on feasibility of cost, schedule, and function.


② 開発DR(Design / Development Review)

Validates design structure and prototype results.
Driven by technical teams with focus on functionality and manufacturability.


③ 量産DR(Production / Manufacturing Review)

Final validation of production readiness.
Focuses on yield, test coverage, process stability, and traceability.

📝 備考|Notes

DR formats vary by organization, but the core goal is always the same:
Ensure technical soundness and product quality through structured collaboration.
