A method of forming plasma used in a process of manufacturing a semiconductor device and a method of forming a layer for a semiconductor device using the plasma are disclosed. The plasma forming method includes forming a plasma region in a sealed space by supplying a plasma source gas into the sealed space at a first flow rate and maintaining the plasma region by supplying a plasma maintenance gas into the sealed space at a second flow rate higher than the first flow rate. The plasma source gas includes a first gas having a first atomic weight, and the plasma maintenance gas includes a second gas having a second atomic weight lower than the first atomic weight. The plasma source gas includes argon and the plasma maintenance gas includes helium. The method may further include forming the layer on a wafer by supplying a source gas into the sealed space.

A chemical vapor deposition apparatus has a showerhead, and temperature control apparatus including a heater and a heat dissipation plate for regulating the temperature of the showerhead. The showerhead includes a bottom plate having gas spray openings, and an upper plate. The heater is disposed on an upper plate of the showerhead. The heat dissipation plate contacts an upper portion of the upper plate of the showerhead above the heater so that heat dissipates from the showerhead through the plate. The temperature control apparatus also includes a coolant system by which coolant is fed into a space defined between the heater and the heat dissipation plate. The temperature of the showerhead is precisely controlled using the heater, the heat dissipation plate and the coolant system.

In an apparatus for forming a layer, the apparatus includes a processing chamber, a chuck, a gas-supplying unit, and a pipe unit. The chuck for supporting a substrate is disposed in the processing chamber. The gas-supplying unit supplies a source gas for forming a layer on the substrate and a purge gas for purging the inside of the processing chamber to the processing chamber. The pipe unit transfers the source gas and the purge gas to the processing chamber at a temperature that falls between the temperature of condensation and a reaction temperature for the source gas so that condensation or deposition reaction does not occur until the source gas enters the processing chamber. A heater located outside of the chamber heats the purge gas that is supplied to the processing chamber to a predetermined temperature.

In a method and an apparatus for depositing a metal compound layer, a first source gas and a second source gas may be provided onto a substrate to deposit a first metal compound layer on the substrate. The first source gas may include a metal and halogen elements, and the second source gas may include a first material capable of being reacted with the metal and a second material capable of being reacted with the halogen element. The first and the second source gases may be provided at a first flow rate ratio. A second metal compound layer may be deposited on the first metal compound layer by providing the first and the second source gases with a second flow rate ratio different from the first flow rate ratio. The apparatus may include a process chamber configured to receive a substrate, a gas supply system, and a flow rate control device.

In methods of manufacturing capacitors, a first metal compound may be deposited on a substrate using first and second source gases. The first and the second source gases may be provided onto the substrate by a first flow rate ratio in which a deposition rate of the first metal compound by surface reaction between the source gases is higher than that by mass transfer between the source gases. A second metal compound may be deposited on the first metal compound and undesired materials may be removed by providing the source gases with a second flow rate ratio different from the first flow rate ratio. Depositing the first and the second metal compounds may be repeated to form a lower electrode. A dielectric layer and an upper electrode may be formed on the lower electrode. Accordingly, permeation of an etching liquid or gas may be reduced during an etching process.
