...The substrate is the single crystal material on which transistors and ICs are formed. Usually, the elemental semiconductor silicon is used, but for high-performance ICs, the compound semiconductor gallium arsenide GaAs is used. After the required wafer processing steps, the ICs are cut into small pieces with sides of a few mm to 3 cm. These are called chips or dies. ... *Some of the terminology that mentions "wafer" is listed below. Source | Heibonsha World Encyclopedia 2nd Edition | Information |
…ここで基板substrateというのは,トランジスターやICがその上に形成される単結晶素材で,通常は元素半導体であるシリコンが使用されるが,高性能ICに対しては,化合物半導体であるガリウムヒ素GaAsが使用される。ICは所定のウェーハー処理工程の後,1辺が数mm~3cm程度の単位ごとの小片に切断される。これをチップchipまたはダイdieと呼ぶ。… ※「ウェーハー」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
