でおる。When a magnetic field is applied to these crystals, the bandgap changes with the magnetic field strength, and the polarization characteristics of light change, making them unique materials that have attracted much attention in recent years.
一方、故意に添加する不純物の1つがMnである半導体

されることか近年明らかとなっている。On the other hand, Mn-doped ZnS and zn3e are typical semiconductors in which Mn is one of the intentionally added impurities. As is well known, ZnS and ZnS are materials that emit light in the visible region, and are widely used in light-emitting diodes, semiconductor lasers, and panel displays, from crystal growth to device applications. Senkyokumonbatsu is in progress. In recent years, it has become clear that doping Mn separately from these (A) improves the crystallinity and the light emission characteristics.
上に挙げた半導体材料を成長する方法としては、有機金
属気相成長方法(MOCVD)や分子線エピタキシー法
(MBF)か必るが、一般にはMB「が用いられている
。その理由は、次に述べるようである。つまり、従来、
Mnの有機金属原料としては、ジシクロペンタジェニル
マンガン(Mn(C5[」5)2)や1〜リカルボニル
メチルシクロペンタジエ−ルマンカン(C6HB Mn
(Co)3)がおる。前者においては、融点か158

膜か得られないという欠点があった。つまり、従来では
MOCVDを行うのに適したMnの有機金属原料かなか
ったわけで必る。Methods for growing the semiconductor materials listed above include metal organic chemical vapor deposition (MOCVD) and molecular beam epitaxy (MBF), but MB is generally used.The reason is as follows. In other words, conventionally,
Examples of organic metal raw materials for Mn include dicyclopentadienylmanganese (Mn(C5['5)2) and 1-licarbonylmethylcyclopentadiene mankane (C6HB Mn
(Co)3) is here. In the former case, the melting point is 158
Because the temperature is as high as .degree. C., it is difficult to precisely control the amount of transport using the bubbling transport method of metal organics normally used in MOCVD. On the other hand, since the latter is a liquid at room temperature, it is suitable for bubbling, but since the raw material contains oxygen, the grown film will oxidize, making it impossible to obtain a high-quality film. In other words, this is necessary because conventionally there was no Mn organic metal raw material suitable for MOCVD.
ところで、前述した材料であるcd丁eやZnSを結晶
成長するには基板が必要であるが、これらの材料の基板
は非常に高価であり、かつ結晶性が低い。このため、基
板としては安価で結晶性に優れたGaASやInSbな
どの■−■族化合物半導体基板が多く用いられている。Incidentally, a substrate is required for crystal growth of the above-mentioned materials CDD and ZnS, but substrates of these materials are very expensive and have low crystallinity. For this reason, 1-2 group compound semiconductor substrates such as GaAS and InSb, which are inexpensive and have excellent crystallinity, are often used as substrates.
このような基板上に成長する場合には、成長層の結晶性
を高めるため、基板と同一組成のバッファ層を成長し、
連続してQd丁eやZnS等を成長するのが望ましい。When growing on such a substrate, a buffer layer with the same composition as the substrate is grown to improve the crystallinity of the growth layer.
It is desirable to continuously grow Qd, ZnS, etc.
このように、■−■族化合物半導体と■−Vl族化合物
半導体を連続して成長させることは■−V族とn −v
i族がお互いに不純物元素の関係にあることから、成長
室が閉じた系で必るMBEでは非常に難しい。ところか

物半導体を連続成長でき、更には■−v族とIr−Vl
族の多層連続成長も可能である。このようにMOCVD
は上)ホした材料を成長する手法として極めて重要な方
法でおる。In this way, the continuous growth of the ■-■ group compound semiconductor and the ■-Vl group compound semiconductor is similar to that of the ■-V group compound semiconductor and the n-v group compound semiconductor.
Since the i-group members are in a relationship with each other as impurity elements, MBE, which is necessary in a closed growth chamber, is extremely difficult. On the other hand, in MOCVD, since the growth system is an open tube system, each growth gas can be completely exhausted from the growth system. As a result, it is possible to continuously grow the n-vi group compound semiconductor on the ■-v group compound semiconductor buffer layer, and furthermore, the n-vi group compound semiconductor and the Ir-Vl group
Multilayer continuous growth of families is also possible. In this way MOCVD
(above) This is an extremely important method for growing such materials.
本発明の目的は、成長原料のうち少なくとも1種でも有
