Abstract
【解決手段】 第1組の通路は、金属含有前駆ガスを導入することができる。第2組の通路は、窒素含有前駆ガスを供給することができる。第1組の通路と第2組の通路は、金属含有前駆ガスと窒素含有前駆ガスが基板に到達するまで分離するように散在されているのがよい。不活性ガスは、また、通路を通して流されて、通路での反応或いは通路の近くでの反応を分離し続け制限するのを助けることができ、それによって通路上への望ましくない堆積が防止される。

Description
[0001]本発明の実施形態は、一般的には、発光ダイオード(LED)のようなデバイスの製造、特に、水素化物気相エピタキシャル(HVPE)堆積に用いられるシャワーヘッド設計に関する。
[0002]III族窒化物半導体は、短波長発光ダイオード(LED)、レーザダイオード(LD)、高電力、高周波、高温のトランジスタと集積回路を含む電子デバイスのような様々な半導体デバイスの開発と製造において、より重要性が認められている。III族の窒化物を堆積させるために用いられてきた1つの方法は、水素化物気相エピタキシャル(HVPE)堆積である。HVPEでは、ハロゲン化物がIII族の金属と反応して、前駆体を含有する金属(例えば、金属塩化物)を形成する。次いで、前駆体を含む金属は、窒素含有ガスと反応して、III族の金属窒化物を形成する。
HX(気体)+ M(液体金属)→ MX(気体)+H(気体)、
式中、X=Cl、Br、又はI、M=Ga、Al、又はIn。
ハロゲンに対して、式は以下の通りである:
Z(気体)+ M(液体金属)→ MZ(気体)、
式中、Z=Cl2、Br、又はI2、M=Ga、Al、又はIn。
以後、気体金属含有化学種は、“金属含有前駆体”(例えば、金属塩化物)と呼ばれる。
[0058]前述した実施形態において、ソースボート中でハロゲン化物或いはハロゲンガスを金属ソースと混合することによって金属含有前駆ガスを形成したが、金属含有前駆ガスをソースボートを実施せずに形成することができる。このような本発明の実施形態は、ソースボート208の必要を排除することができ、それによって、基板表面全体に金属窒化物の堆積の均一性を維持し且つ望ましくない表面上への堆積を制限しつつ、生産を簡易化することができる。
[0061]前述の実施形態において、前駆ガスを、基板表面で或いはその近くで金属窒化物が形成される処理容積部108に、別々のチューブを通して分配したが、金属含有前駆ガスと窒素含有前駆ガスを、処理容積部、処理容積部の外側であるが処理チャンバの内側、或いは処理チャンバの完全に外側で、摂氏50度と摂氏550度の間に温度制御できる混合域で混合してもよく、処理チャンバは、図1において全体の装置として画成されている。このような本発明の実施形態は、(1)混合の均一性の改善し、(2)設計を簡易化し、(3)表面上の望ましくない堆積と前駆体の減少を最少にする。
