基板
解説 Definition
substrates は substrate（基板、基質、下地）の複数形です。電子部品や生物学、化学などで、何かを支えたり反応の土台になったりする材料や物質を指します。
Substrates are supporting base materials or surfaces on which electronic components, circuits, or sensors are formed or mounted. The word is the plural of substrate and may refer to several materials whose properties affect a device’s performance.
覚え方のコツ Memory Tip
substrate の規則的な複数形で、語尾に -s を加え、発音は /ˈsʌbstreɪts/ と最後が /s/ になります。sub-「下」＋strate「層」の構成から、部品や反応を下で支える土台を連想します。電子分野では circuit や sensor を載せる複数の基板という語義に絞って覚えます。
Break substrate into sub-, “under,” and a part related to stratum, “a laid-down layer.” A substrate is therefore the supporting layer underneath something else. Substrates is its regular plural, made by adding -s; because substrate ends in the voiceless sound /t/, the plural ending is pronounced /s/: /ˈsʌbstreɪts/. In electronics, picture several flat base materials carrying circuits, components, or sensors. Learn combinations such as circuit substrates, ceramic substrates, and different substrates. The singular names one base; the plural refers to two or more bases or material types.
例文
The engineer tested several substrates for the new circuit.
技術者は新しい回路用にいくつかの基板を試験しました。
These substrates must stay clean during production.
これらの基板は製造中ずっと清潔に保たなければなりません。
Different substrates can change the performance of a sensor.
基板が異なると、センサーの性能が変わることがあります。

substrates の語源・成り立ち Etymology
substratesはラテン語substratum「下に敷かれたもの」由来で、sub-「下」＋stratum「敷かれた層」から成ります。もともと「下にある土台・層」の感覚があり、そこから基板や基層の意味に発展しました。関連語はstratum, stratify。
Substrates is the plural of substrate. Substrate comes from Latin substratum, meaning “something laid underneath,” formed from sub-, “under,” and a form related to sternere, “to spread or lay down.” Stratum is likewise a laid-down layer. The word first expressed the general idea of an underlying layer or foundation and later acquired specialized senses in electronics, biology, and chemistry for a supporting material or a substance on which a process occurs.
