Definitions
- the invention relates to a method for producing semiconductor wafers with an epitaxial layer in a chamber of a deposition reactor by means of gas phase deposition.
- a process is interrupted from time to time to service the chamber, particularly to clean up material that has deposited on interior walls of the chamber.
- the chamber is in a state that does not yet allow to coat semiconductor wafers therein that meet the expectations, in particular with regard to the required lifetime of minority charge carriers in the epitaxial layer. It is therefore necessary to condition the chamber, which limits the productivity of the process.
- US 20080219824 A1 describes a typical system with which a method for producing semiconductor wafers with an epitaxial layer can be carried out by means of vapor deposition.
- a plant usually includes several deposition reactors, a lock chamber (load lock chamber) and a transfer chamber.
- a deposition reactor includes in particular an upper cover (upper mandrel), a lower cover (lower mandrel), a base ring (base ring) and an upper and a lower clamping ring (upper and lower liner), which belong together to a chamber in which the Vapor phase deposition takes place.
- the chamber houses a susceptor support shaft with support arms, a wafer lift shaft, and a susceptor.
- the susceptor support shaft and disc lift shaft are connected to a rotary lift unit.
- Lamp modules and reflectors are positioned above the top cover and below the bottom cover to provide radiant energy within the chamber during vapor deposition.
- DE 11 2016003399 T5 suggests flushing the chamber of a deposition reactor with nitrogen for the purpose of conditioning in the system, heating the inside of the chamber and measuring the lifetime of minority charge carriers of test wafers to decide whether to continue the production of semiconductor wafers with an epitaxial layer can be.
- the object of the present invention is to reduce such a restriction and to propose a particularly effective conditioning.
- the object of the invention is achieved by a method for producing semiconductor wafers with an epitaxial layer in a chamber of a deposition reactor of a plant, comprising the repeated deposition of an epitaxial layer on a substrate wafer in the chamber of the deposition reactor, a first number of semiconductor wafers with an epitaxial layer being produced , and meanwhile conditioning a spare chamber of the off-site deposition reactor by purging the spare chamber with a purge gas; interrupting the repeated deposition of an epitaxial layer on a substrate wafer; replacing the chamber with the spare chamber; and continuing to repeatedly deposit an epitaxial layer on a substrate wafer in the spare chamber of the deposition reactor, resulting in a second plurality of epitaxial layer semiconductor wafers.
- the time of limited productivity due to the conditioning of the chamber is significantly reduced when using the method according to the invention and is due in particular to the time it takes to replace the chamber with the spare chamber.
- the chamber replaced by the spare chamber once replaced, itself becomes a spare chamber that can be conditioned off-site.
- the attachment comprises a deposition reactor, preferably at least one further deposition reactor.
- a replacement chamber preferably includes as components a top cover, a bottom cover, a base ring, top and bottom clamp rings, a susceptor support shaft with support arms, a disc lift shaft, a susceptor, a bottom lamp module with bottom reflectors, and a rotary hub -Unit for the waves. These components are assembled during conditioning of the replacement chamber in the same manner as during vapor deposition.
- An optional upper lamp module with upper reflectors may also be part of the spare chamber.
- the conditioning of the spare chamber is carried out outside the plant on a conditioning stand and includes flushing the spare chamber with a flushing gas and preferably one or two other measures.
- the purge gas is directed through the spare chamber from at least one gas inlet to at least one gas outlet.
- the proportion of water in the flushing gas when the flushing gas enters the replacement chamber is preferably less than 100 ppm, particularly preferably less than 50 ppm.
- the flushing gas is preferably free of particles, in particular free of metallic particles.
- the purge gas is nitrogen, hydrogen, helium, argon or a mixture of at least two of the gases mentioned. Nitrogen is preferably used as the flushing gas. When flushing the spare chamber, it should be ensured that there are as few dead spots as possible inside the spare chamber where the flow rate of the flushing gas decreases to such an extent that it disappears.
- Other measures include increasing the temperature inside the replacement chamber compared to the temperature surrounding the replacement chamber, for example by means of IR radiation, heating mats or heat exchangers or a combination thereof.
- the temperature at points of the components of the replacement chamber where there is contact with the interior of the replacement chamber is more than 21°C, preferably more than 65°C.
- the upper limit for the temperature is basically only the temperature resilience of the material being heated.
- the other measures also include changing the pressure in the interior of the replacement chamber during conditioning, with the pressure change being able to be carried out in two different ways. Either by lowering the pressure inside the spare chamber compared to the pressure at the conditioning stand, or by increasing the pressure inside the spare chamber compared to the pressure at the conditioning stand. Valves and/or a vacuum pump at the gas outlet of the spare chamber can be used to lower the pressure.
- a combination of the two types of pressure changes can also be carried out, for example by first increasing the pressure of flushing gas in the interior of the spare chamber and then lowering it to below the pressure at the conditioning stand by sucking off the flushing gas at the gas outlet.
- the conditioning of the replacement chamber is carried out for a predetermined period of time or preferably until the proportion of water in the flushing gas when leaving the replacement chamber has reached or fallen below a predetermined threshold value.
- the humidity in the flushing gas can be measured, for example, at the gas outlet of the replacement chamber.
- the replacement chamber can be closed to prevent the ambient atmosphere from entering the interior of the replacement chamber during transport to the plant.
- the pressure difference between the pressure in the interior and the pressure in the vicinity of the closed replacement chamber should be as small as possible during the transport of the replacement chamber to the facility in order to avoid a possible implosion of the replacement chamber.
- Replacing the chamber with the conditioned replacement chamber should then be done under an atmosphere of dry purge gas to avoid introducing moisture into the replacement chamber when changing the chambers.
- the transport to the plant and the replacement of the chamber can also be carried out with continued flushing of the replacement chamber with dry flushing gas, so that there is no pressure difference between the interior and the environment.
- a flow rate of 3 Nl/min to 8 Nl/min is recommended in this case.
- the semiconductor wafers produced according to the invention preferably consist of silicon or comprise substrate wafers made of silicon with at least one epitaxial layer made of silicon germanium or with at least one epitaxial layer made of gallium nitride.
- the diameter of the semiconductor wafers is preferably at least 200 mm, particularly preferably 300 mm.
- FIG. 1 shows a flow chart for the conditioning of a replacement chamber on a conditioning stand according to an embodiment of the invention.
- the replacement chamber 1 includes as components an upper cover, a lower
- a gas supply 4 dry flushing gas is passed through the spare chamber 1, the amount of gas flow being adjusted by valves 5 at the gas inlet and the power of a pump 6 at the gas outlet.
- the schedule provides for the temperature in the interior of the replacement chamber 1 to be increased by means of a heater 7 and for the humidity of the flushing gas to be determined after it has left the replacement chamber 1 by means of a measuring apparatus 8 .
