Abstract
Description
・長方形以外のセンサ基板は、センサチップの繊細な圧力感応領域を片持ち支持する。
・長方形以外のセンサ外形によって、(センサ基板を再び方向付けることで)ガイドワイヤの先端に極めてコンパクトにセンサを搭載できる。
・圧力センサにおける精密な切り欠きによって、センサにワイヤを取り付ける又リードワイヤの取り付けのための張力を緩和する簡単な構成を採用できる。
DRIE法とラッピング(機械的基板から過剰なシリコンを除去すること)又はその他のウェーハを薄くする方法を用いて、薄くて精巧なウェーハによって取り付けられたフレームを含む多数のセンサチップの製造が容易に行えるようにした方法について説明する。
