Semiconductor articles assume you know the factory map

A technology article says:

先端半導体の量産には、露光装置、微細化技術、材料、パッケージング、歩留まり改善が不可欠である。

The words are short, but the process is complex. Semiconductor Japanese mixes engineering, manufacturing, corporate strategy, supply chain, and policy.

The key principle is:

Semiconductor Japanese must be read by process stage and company role.

A company may make chips, design chips, provide equipment, supply materials, package chips, or operate a foundry. The same article may move among all of these.

半導体

半導体

means semiconductor.

It may refer to:

  • semiconductor materials,
  • chips/devices,
  • semiconductor industry,
  • manufacturing technology,
  • policy field.

Related:

半導体産業 semiconductor industry

半導体不足 semiconductor shortage

先端半導体 advanced semiconductors

Learner action: identify whether 半導体 means material, chip, industry, or policy topic.

ウエハー

ウエハー

means wafer.

Related:

シリコンウエハー silicon wafer

ウエハー工程 wafer process

前工程 front-end process

The wafer is the substrate on which many chips are formed.

Learner action: wafer language usually belongs to fabrication/front-end process.

露光

露光

means lithography/exposure.

Related:

露光装置 lithography equipment

EUV露光 EUV lithography

フォトレジスト photoresist

露光 is a core process for patterning circuits.

Learner action: if 露光 appears, the article is likely about advanced manufacturing capability.

微細化

微細化

means miniaturization / making features finer.

Related:

微細化技術 miniaturization technology

回路線幅 circuit line width

プロセス技術 process technology

微細化 is tied to performance, power efficiency, cost, and manufacturing difficulty.

製造装置 and materials

製造装置

means manufacturing equipment.

材料

means materials.

Semiconductor production depends on specialized equipment and materials:

洗浄装置 cleaning equipment

成膜装置 deposition equipment

エッチング装置 etching equipment

レジスト材料 resist material

Learner action: equipment and material companies are part of the semiconductor ecosystem even if they do not make chips.

ファウンドリ

ファウンドリ

means foundry, a company that manufactures chips for other companies.

Related:

受託製造 contract manufacturing

設計 design

ファブレス fabless

A fabless company designs chips but does not manufacture them in its own fabs. A foundry manufactures.

Learner action: identify whether the company role is design, manufacturing, equipment, materials, or packaging.

パッケージ

パッケージ

in semiconductor context means package/packaging, not consumer packaging.

Related:

後工程 back-end process

先端パッケージ advanced packaging

実装 mounting/implementation/packaging context

Packaging connects the chip to the outside system and affects performance, heat, integration, and cost.

Learner action: do not translate パッケージ as retail package in semiconductor articles.

歩留まり

歩留まり

means yield.

In semiconductor manufacturing, yield is critical because tiny defects can ruin chips.

Related:

歩留まり改善 yield improvement

不良 defect

量産立ち上げ ramping up mass production

Learner action: yield tells whether a process is commercially viable, not just technically possible.

量産

量産

means mass production.

Related:

量産開始 start of mass production

量産体制 mass-production system/capacity

試作 prototype/trial production

A technology can exist in prototype but not be ready for mass production.

Learner action: distinguish demonstration, pilot line, and mass production.

Supply-chain and policy language

Semiconductor articles often include:

供給網 supply chain

経済安全保障 economic security

国内生産 domestic production

補助金 subsidy

調達 procurement

This is why semiconductor Japanese is also policy Japanese.

Example bank walkthrough

半導体

Learner action: material, chip, industry, or policy?

露光

Lithography/exposure.

Learner action: patterning process.

微細化

Miniaturization.

Learner action: advanced process concept.

パッケージ

Semiconductor package/packaging.

Learner action: back-end process, not retail packaging.

ウエハー

Wafer.

Learner action: fabrication substrate.

製造装置

Manufacturing equipment.

Learner action: equipment supply role.

歩留まり

Yield.

Learner action: production viability metric.

ファウンドリ

Foundry.

Learner action: contract chip manufacturer.

材料

Materials.

Learner action: supply-chain input.

量産

Mass production.

Learner action: commercial production stage.

Semiconductor article map

When reading semiconductor Japanese:

  1. Process stage: design, front-end, back-end, packaging, testing?
  2. Company role: fabless, foundry, equipment, material, IDM, government?
  3. Technology: lithography, miniaturization, packaging, material.
  4. Product: memory, logic, sensor, power semiconductor?
  5. Production status: prototype, pilot, mass production?
  6. Metric: yield, capacity, node, investment, subsidy.
  7. Supply-chain issue.
  8. Policy/security implication.
  9. Market/customer implication.

Semiconductor process-chain table

Semiconductor Japanese becomes clearer when mapped to process stage.

Stage/layerTermsWhat to ask
material材料, シリコンwhat inputs?
waferウエハーsubstrate stage

miniaturization微細化node/performance/cost issue
equipment製造装置who supplies tools?
yield歩留まりproduction efficiency
packagingパッケージ, 後工程assembly/integration
mass production量産commercial scale?
foundryファウンドリcontract manufacturing role

This prevents news articles from becoming a pile of technical nouns.

Company-role distinction

Semiconductor articles may mention:

ファウンドリ contract manufacturer

製造装置メーカー equipment maker

材料メーカー materials supplier

設計会社 design company

IDM integrated device manufacturer

A company’s role matters more than whether it is simply “in semiconductors.”

技術 and policy layer

Semiconductor Japanese often jumps from technical terms to industrial policy:

量産体制 mass-production system

供給網 supply chain

経済安全保障 economic security

補助金 subsidy

When reading, classify each paragraph as technology, production, company strategy, supply chain, or policy.

A strong tool for this article would classify semiconductor terms by supply-chain and process stage.

Suggested functions:

  1. Process-stage labels: design, wafer, lithography, packaging.
  2. Company-role classifier.
  3. Equipment/material glossary.
  4. Yield and mass-production status flags.
  5. Policy-term detector: 補助金, 経済安全保障.
  6. Plain article summary.
  7. Technical caution label.

Final rule

Semiconductor Japanese is process-stage language.

半導体 names the field. ウエハー starts the fabrication surface. 露光 patterns. 微細化 advances. 材料 and 製造装置 enable. ファウンドリ manufactures. パッケージ connects. 歩留まり decides viability. 量産 makes it real.

Read the factory map behind the headline.
