Abstract
【解決手段】半導体製造方法は、成長基板を提供する工程S11と、前記成長基板に半導体基板を形成する工程S12と、前記成長基板と前記半導体基板との間に複数の溝を有する第一構造を形成する工程S13と、後続の素子の製造を進め、半導体素子を半導体基板に形成する工程S14と、前記成長基板の温度と前記半導体基板を変更する工程S15とを含んでいる。工程S15において、成長基板と半導体基板とは膨張係数が異なるので、応力が集中し、互いに剥離する。このように、レーザ剥離技術によって成長基板を除去する工程を必要としないため、コストを効果的に減少させることができる。
【選択図】図1
Description
第一の実施形態を図1から図5を用いて説明する。
上記第一構造22を形成する方法は、第一の実施形態により提供されるフローチャートに限定されていない。第二の実施形態を図6から図10を用いて詳細に説明する。図6は、本発明の第二実施形態によるフローチャートである。図7から図10は、本発明の第二実施形態による構造を示す図である。第二実施形態には、第一実施形態と同様に、複数の溝を有する第一構造33は、半導体基板31と成長基板1との間の接触面積を減らすために、成長基板1に隣接する場所で形成される。第二実施形態の第一構造33を形成する方法は、第一実施形態と異なり、その手順は以下のように示す。
2 半導体基板
3 半導体素子
4 接合基板
22 第一構造
2a 誘電体層
2a 1第二構造
