Definitions
- the present invention relates to an electronic device manufacturing method using a plasma reactor processing system suitable for manufacturing an electronic device such as a liquid crystal device or a semiconductor device.
- This type of plasma reactor processing system includes a process chamber containing a plasma generator (eg, parallel plate electrode system, microwave antenna system, etc.), and one or more inert gas sources. (Eg, Ar, Kr, Xe, etc.) and an inert gas supply line connecting each of the process chambers and one or more process gas sources (eg, H2, 02, NF3, C12, SiC14, HBr, SF6, C5F8, CF4, etc.) and a process gas supply line connecting the process chamber and a chamber gas discharge line connecting the process chamber and the exhaust pump.
- a plasma generator eg, parallel plate electrode system, microwave antenna system, etc.
- inert gas sources eg, Ar, Kr, Xe, etc.
- an inert gas supply line connecting each of the process chambers and one or more process gas sources (eg, H2, 02, NF3, C12, SiC14, HBr, SF6, C5F8, CF4, etc.) and a process gas supply line connecting the
- Each inert gas and each process gas supply line is provided with a flow rate regulator capable of adjusting the flow rate of the gas flowing through the line to a set value.
- the discharge pipe has a function to automatically change the opening of the flow control valve in a direction in which the deviation between the given pressure setting value and the pressure measurement value measured via the pressure measurement unit decreases.
- a pressure controller is interposed!
- the present invention has been made by paying attention to the above-mentioned problems, and its object is At the start of the process, in the middle of the process, at the end of the process, etc., the concentration of the atmosphere in the process chamber can be changed instantaneously, and the plasma reaction process required for the production of liquid crystal devices and semiconductor devices can be reduced with high productivity. To provide an electronic device manufacturing method using a plasma reactor processing system that can be realized at a low cost.
- the supply of process gas is started (concentration change) at time t31, and the operation mode of APC4 is changed from the first operation mode (pressure setting mode).
- the operation mode of APC4 is changed from the first operation mode (pressure setting mode).
- Switch to the second operation mode (valve opening setting mode), and at the same time, give the APC4 the valve opening setting value empirically determined to mitigate pressure fluctuations immediately after the change.
- step 1205 setting of the HBr flow rate value for the FCS of the HBr gas (excess amount in Fig. 4).
- the manufacturing method including the concentration changing process of the present invention uses, for example, PLC9, FCS;! To FCS11, solenoid valve SV;! To SV11, APC4, microwave power source 6, RF This can be realized by appropriately controlling the power supplies 7, 8 and the like.
- FIG. 13 shows a flowchart for explaining the effect of the present invention in comparison with the conventional example.
- step 1310 in the conventional manufacturing method, after supplying the process gas (switching from the inert gas to the process gas) (step 1310), After waiting for the process gas concentration and pressure to stabilize at the target values (step 1 311), the plasma power supply is turned on to start the process treatment reaction (step 1312). So At the end of the process treatment reaction, the plasma power is turned off to finish the process treatment reaction (step 1313), and then the process gas supply is stopped (switching from process gas to inert gas) (step 1314). Until the gas concentration and pressure in the process chamber are stabilized at the target values, the process waits for the next process (for example, opening the process chamber door and taking out the substrate) (step 1315). In this case, the time for waiting for the gas concentration and pressure in the chamber to stabilize is a wasteful time without any processing.
- the process gas supply start (step 1320) and the plasma power supply ON (step 1321) may be performed almost simultaneously.
- the plasma power supply OFF (step 1322) and the process gas supply stop (step 1323) may be performed almost simultaneously.
- the process gas may be a mixture of a material gas (a gas used as a material such as a film generated by the process) and an inert gas, or may be only a material gas.
- the process gas supply starts (switching from the inert gas to the process gas). (Step 1331). At the end of the process, the process gas supply is stopped (switching from process gas to inert gas) (step 1332), and then the plasma power supply is turned off (step 1333). Unlike the prior art, this is possible because the gas concentration in the process chamber 1 instantaneously reaches the target value and stabilizes, and the process can be executed from the moment the gas is supplied.
- the process gas supply start switch from the inert gas to the process gas
- the plasma power supply may be turned on almost simultaneously. Switching to gas) and plasma power OFF may be performed almost simultaneously.
- the process gas may be a mixture of a material gas (a gas used as a material such as a film generated by the process) and an inert gas, or may be only a material gas.
- the process gas introduced into the reaction furnace can be immediately converted to plasma and contribute to the plasma reaction process, the use efficiency of the process gas is improved, and the manufacturing cost is correspondingly increased. descend.
- productivity can be improved by shortening the TAT (Tum_Around Time) of the process.
- the supplied process gas does not waste power at the start of the plasma reaction process, thereby improving productivity and reducing process gas.
- a method for manufacturing an electronic device using the plasma reactor processing system of the present invention includes manufacturing a semiconductor device, a solar cell, a large flat display device (liquid crystal display device, organic EL display device, etc.), and other electronic devices. This can be applied to plasma reaction processing (plasma oxidation processing, plasma nitridation processing, plasma CVD processing, plasma etching processing, plasma ashing processing, etc.) of substrates and plasma cleaning processing of chamber inner walls, etc. . That is, the method of the present invention is suitable for use in general production of electronic devices.
