Description
従来の半導体デバイスの微細化はデバイスの回路の構造を2次元的に微細化することにより、半導体ウエハ1枚当りで製造できる素子の数を増加させて素子1個を製造するに要するコストを低下させると共に、配線長を短縮してデバイスの演算、信号の入出力の単位時間当たりの量や消費電力の低減等の性能の向上も図れてきた。しかし、このような2次元的なデバイスの回路の構造の微細化は限界が近づいているといわれており、近年では新材料や3次元的な素子構造を適用する等の別の技術の開発が為されている。一方で、このような材料や回路の構造の変更により、半導体デバイスの製造の難易度は増し、製造コストの増大が深刻な問題となっている。
特に、特性を固定した円偏波発生器の取り付け位置を最適化して、円偏波の軸比を検出したものである。
