- Line 9 may have an exhaust valve for adjusting the exhaust flow rate or for adjusting the pressure in the deposition chamber 2.
- steps (i) to (iv) form one cycle, which can be repeated multiple times depending on the desired film thickness.
- the process conditions are as follows: Starting compound: (3,3-dimethyl-1-butyne) dicobalt hexacarbonyl: Raw material compound gas flow rate: 0.003 scc (Standard Cubic Sentimeters)/cycle x 5 cycles Reactive gas: hydrogen Reactive gas flow rate: 14 scc/cycle x 3 cycles Carrier gas: nitrogen Carrier gas flow rate: 5 ccpm Evaporator set temperature: 70°C Temperature setting in film formation chamber: 200° C.
- ⁇ Common Process> The raw material compound as the raw material liquid is heated to a set temperature while being stirred. At the same time, the film formation chamber is heated to a set temperature. A carrier gas is supplied at a set flow rate (5 sccm) by a mass flow controller. The valve 25 is opened for 10 seconds to remove the gas phase from the evaporator. Then, the valve 25 is closed.
- Example Process After the above common process, the following steps are performed. (1) Repeat the following five times. Open valve 21 ⁇ close valve 21 after 1 second ⁇ open valve 22 after 0.75 seconds ⁇ close valve 22 after 1 second. (2) 0.25 seconds after (1), valve 25 is opened, and 2 seconds after (1), valve 25 is closed. (3) Two seconds after (1), repeat the following three times. Open valve 23 -> close valve 23 after 1 second -> open valve 24 after 0.75 seconds -> close valve 24 after 1 second (4) (3) and then return to (1) again 5 seconds later.

Open valve 21 ⁇ close valve 21 after 1 second ⁇ open valve 22 after 0.75 seconds ⁇ close valve 22 after 1 second (2) (1) The following is repeated three times two seconds after (1). Open valve 23 ⁇ close valve 23 after 1 second ⁇ open valve 24 after 0.75 seconds ⁇ close valve 24 after 1 second. (3) Return to (1) again 5 seconds after (2).
- the small fluctuations near the saturated vapor pressure in Fig. 2 are pressure fluctuations during pulse supply in Example Process (1). After the pulse supply is completed, impurities due to thermal decomposition are removed by evacuating to about 100 Pa in Example Process (2). Thereafter, the evaporation of the raw material proceeds quickly by providing a raw material stirring mechanism, and after the reactive gas is supplied in Example Process (3), the raw material vapor pressure recovers to near the saturated vapor pressure, and when the raw material is supplied again in pulse supply in Example Process (4), it can be supplied at a constant pressure. This confirmed that a stable ALD process can be performed.
- the evaporation of the raw material proceeds quickly due to the stirring mechanism, but the decomposition products accumulate in the container because the impurities are not removed by vacuuming.
- the pressure inside the container greatly exceeds the saturated vapor pressure, and the pressure during the pulse supply of the raw material (small fluctuation part) continues to rise with each cycle. This means that the raw material cannot be supplied at a constant pressure, and the impurity ratio in the raw material also continues to rise, confirming that a stable ALD process cannot be performed.
- the film formation method disclosed herein can efficiently form thin films with high purity, and can therefore be used for a variety of applications, such as the manufacture of circuit boards.

原料化合物:(3,3-ジメチル-1-ブチン)ジコバルトヘキサカルボニル:
反応性ガス:水素 反応性ガス流量:14scc/サイクル×3サイクル
キャリアガス:窒素
キャリアガス流量:5ccpm
蒸発器の設定温度:70℃
成膜室の設定温度:200℃
原料液体としての原料化合物を、攪拌しながら、設定温度にて加熱する。同時に、成膜室を設定温度に加熱する。キャリアガスをマスフローコントローラーにより設定流量(5sccm)にて供給する。バルブ25を10秒開けて、蒸発器の気相を除去する。その後、バルブ25を閉じる。

(3)(2)の5秒後に再度(1)に戻る。
一方、比較例プロセスにおいては、撹拌機構により速やかに原料の蒸発は進むものの、真空引きによる不純物の除去がないために、分解物が容器内に蓄積する。図3に示すように、容器内圧力は飽和蒸気圧を大きく超え、原料のパルス供給時(小刻みな変動部分)の圧力はサイクルを重ねるごとに上昇し続けている。これは、一定圧力にて原料が供給できていないことに加え、原料中の不純物比率も上がり続けることを意味しており、安定的なALDプロセスを行うことができていないことが確認された。
