Description
図1は、本発明のSOI基板の製造方法のプロセス例を説明するための図で、図1(A)に図示された基板10は単結晶Si基板、基板20は石英基板である。ここで、単結晶Si基板10は、例えば、CZ法(チョクラルスキ法)により育成された一般に市販されているSi基板であり、その導電型や比抵抗率などの電気特性値や結晶方位や結晶径は、本発明の方法で製造されるSOI基板のSOI層(Si薄膜層)に形成される半導体素子の設計値やプロセスあるいは個々のマイクロチップの面積などに依存して適宜選択される。また、この単結晶Si基板10はその表面(貼り合せ面)に予め酸化膜が形成された状態のものであってもよい。
図3(A)は、本発明のマイクロチップの第1の構成を説明するための断面図で、この図に示されたマイクロチップは、被測定試料からの蛍光や吸収光を分析する半導体素子が搭載されたチップである。この図において、符号12および20はそれぞれ、SOI層および石英基板であり、石英基板20の一方主面には、凹部21が形成され、この凹部21に感応膜22が設けられている。この感応膜22は、被測定試料そのものであったり被測定試料を付着・保持させる膜であったりするもので、例えば、DNA、脂質膜、酵素膜、抗体膜、窒化膜などである。また、被測定試料が抗体である場合は、抗原を予め凹部21に付着させるようにしてもよい。その場合には抗体が「感応膜」となる。
図4は、本発明のマイクロチップの第2の構成を説明するための断面図で、この図に示されたマイクロチップは、被測定試料のもつ電荷量に応じて変化する表面電位(SOI層の表面電位)を検知可能なLAPS(Light Addressable Potentiometric Sensor)を搭載したチップである。
