Description

  The present invention relates to a substrate processing method for processing a substrate, a substrate processing apparatus, and a droplet holding jig for holding droplets attached to the surface of the substrate. In particular, the present invention relates to a substrate processing method, a substrate processing apparatus, and a droplet holding jig characterized by a method and configuration for processing the surface of a substrate with droplets.

A substrate processing method is implemented to process the surface of a substrate with droplets.
A substrate processing apparatus is used to process the surface of the substrate with droplets.
A droplet holding jig is used to hold droplets attached to the surface of the substrate when the substrate is processed.
When the surface of the substrate is hydrophobic to the droplet, the droplet attached to the surface of the substrate is held by an existing droplet holding jig.
When the surface of the substrate is hydrophilic, the droplets try to spread along the surface of the substrate, so that it is difficult to hold the droplets adhering to the surface of the substrate as one unit.
When the surface of the substrate is rough due to an etching process or the like, the droplets are caught by fine irregularities on the surface of the substrate, so it is difficult to hold the droplets adhering to the surface of the substrate as one unit, It is difficult to move the droplet along the surface of the substrate.
For example, a substrate processing apparatus is used in a semiconductor or liquid crystal manufacturing facility or inspection facility.
The substrate processing apparatus is an apparatus that processes a substrate. For example, the substrate is a substrate such as a semiconductor wafer, a sapphire wafer, or a liquid crystal substrate. The semiconductor wafer is a wafer of silicon, gallium, silicon carbide or the like.
A substrate processing apparatus is used when accurately measuring the amount of impurities such as sodium, potassium, and iron contained in the surface of a semiconductor wafer or the like.

For example, the purpose and method for accurately measuring impurities on the surface of a semiconductor wafer will be briefly described.
If an impurity is contained in a thin film such as an oxide film or a nitride film formed on the surface of a semiconductor wafer, even if the amount of the impurity is very small, the electrical characteristics of the semiconductor element are greatly affected.
Accordingly, there is a demand for suppressing the contamination of impurities from the wafer surface as much as possible in a semiconductor device manufacturing facility.
For this purpose, the amount of impurities present on the surface of the semiconductor wafer is accurately measured.

Instead of secondary ion mass spectrometry, Auger spectroscopy, or neutron activation analysis, which has recently been used to measure the amount of impurities present on the wafer surface, it has a fluoride solution, and the amount of impurities Measure. For example, the fluoride solution is an aqueous HF (hydrogen fluoride) solution.
After the oxide film on the surface of the silicon wafer is dissolved in an HF (hydrogen fluoride) aqueous solution, the HF (hydrogen fluoride) aqueous solution is collected and the impurities in the HF (hydrogen fluoride) aqueous solution are analyzed. Done. When the amount of the collected HF (hydrogen fluoride) aqueous solution is small, the impurity concentration increases, and the measurement accuracy is improved.
For example, after exposing the substrate to the vapor of HF (hydrogen fluoride) aqueous solution and dissolving the oxide layer of the substrate, a droplet of HF (hydrogen fluoride) aqueous solution is dropped on the surface of the substrate, and the droplet is applied to the substrate. Move while attached to the surface. Impurities in the oxide film are collected in the droplets. The amount of impurities on the substrate surface is inspected by measuring the amount of impurities in the droplet.
For example, the amount of impurities in a fluoride solution droplet is measured by an ICP mass analyzer.

In the above case, the substrate processing apparatus is used to drop droplets on the surface of the substrate, and a jig or the like is used to scan the droplets on the surface of the substrate, thereby dissolving the oxide layer on the surface of the scanned region.
Since the silicon wafer and the HF (hydrogen fluoride) aqueous solution have a hydrophobic relationship, droplets of the HF (hydrogen fluoride) aqueous solution become spherical on the surface of the silicon wafer. When the spherical droplet is held and moved by a jig, the droplet can be moved along a predetermined locus on the surface of the substrate very easily.

However, if the surface of the silicon wafer is after the etching process, there are fine irregularities on the surface, making it difficult to hold and move the droplets on the surface of the substrate.
In addition, when the substrate and the droplet are in a hydrophilic relationship, it becomes more difficult to move the droplet while holding the droplet on the surface of the substrate.
For example, the surface of a sapphire wafer is hydrophilic.
In consideration of the above circumstances, the inventor applied droplets adhering to the surface of the substrate without being affected by differences in hydrophobicity and hydrophilicity and differences in surface roughness of the substrate. An attempt was made to devise a method and structure capable of holding, and an attempt to devise a method and structure capable of relatively moving droplets along the surface of the substrate.

Next, the substrate processing method concerning 1st embodiment of this invention is demonstrated based on figures.
FIG. 14 is a flowchart of the substrate processing method according to the first embodiment of the present invention.

  The substrate processing method according to the first embodiment includes a preparation step S10, an adhesion step S20, a scanning step S40, a recovery step S50, and a measurement step S60.

  The preparation step S10 is a step of preparing the droplet holding jig 10, the liquid supply device 20, and the scanning device 30.

The attaching step S20 is a step of attaching droplets to the surface of the substrate.
For example, in the state where the opening O is directed toward the surface of the substrate 5 and the substrate recovery jig is held, when the gas is ejected from the opening O toward the surface of the substrate 5, the surface of the substrate passes through the through hole H. Drop droplets on
The droplet P adheres to the surface of the substrate 5.
The amount of the liquid that forms the droplet P is an amount that does not protrude from the space surrounded by the opening O.
An appropriate amount of the liquid that forms the droplet P is affected by the state of the surface of the substrate, the viscosity of the liquid, or the wettability between the surface of the substrate and the liquid.
For example, when the droplet holding jig according to the first embodiment is used, the droplet adheres to the end surface S of the end surface portion.
For example, when the substrate inspection jig according to the fourth embodiment is used, the droplet holding jig does not contact the droplet.

The scanning step S40 holds the jig so that the droplets attached to the surface of the substrate are surrounded by the opening when viewed from the direction orthogonal to the surface of the substrate, and the jig is mounted on the substrate while blowing gas from the opening to the surface of the substrate. It is the process of making it move relatively along the surface.
When the droplet holding jig 10 according to the fifth to sixth embodiments is used, the jig is further moved along the surface of the substrate 5 while the C-shaped opening O is moved relative to the jig. Position it behind the trajectory.
According to a predetermined procedure, the rotating device 32 rotates the substrate, and the swing device 34 moves the droplet holding jig 10 in the radial direction of the substrate.
The droplet P moves along the surface of the substrate 5.
If the droplet is a liquid that treats the substrate, the surface of the substrate 5 is treated.

In the collecting step S50, the droplets adhering to the surface of the substrate 5 are collected.
For example, droplets adhering to the surface of the substrate 5 are sucked up using a dropper-like device.
For example, in the state where the opening O is directed toward the surface of the substrate 5 and the substrate recovery jig is held, when the gas is ejected from the opening O toward the surface of the substrate 5, the surface of the substrate passes through the through hole H. Collect droplets adhering to.
Further, for example, the droplet holding jig 10 is retracted from the surface of the substrate, and the droplets adhering to the surface of the substrate 5 are sucked up using a dropper-like device.

The measurement step S60 is a step of measuring a droplet.
For example, measure the amount of metal atoms contained in a droplet

Next, the substrate processing method concerning 2nd embodiment of this invention is demonstrated based on figures.
FIG. 15 is a flowchart of the substrate processing method according to the second embodiment of the present invention.

  The substrate processing method according to the second embodiment includes a preparation step S10, an adhesion step S20, an initial step S30, a scanning step S40, a recovery step S50, and a measurement step S60.

  The preparation step S10 is a step of preparing the droplet holding jig 10, the liquid supply device 20, and the scanning device 30.

The attaching step S20 is a step of attaching droplets to the surface of the substrate.
For example, the substrate recovery jig is held with the opening O facing the surface of the substrate 5, and when the gas is blown out from the opening O toward the surface of the substrate 5, the liquid passes through the through hole H and reaches the surface of the substrate. Add drops.
Further, for example, the droplet holding jig 10 is retracted from the surface of the substrate, and the droplet is dropped at a desired position on the surface of the substrate.
The droplet P adheres to the surface of the substrate 5.

  In the initial step S30, the end surface S is brought close to the surface of the substrate 5 with the opening O facing the surface of the substrate 5, and the end surface S is brought into contact with the droplet attached to the surface of the substrate.

The scanning step S40 holds the jig so that the droplets attached to the surface of the substrate are surrounded by the opening when viewed from the direction orthogonal to the surface of the substrate, and the jig is mounted on the substrate while blowing gas from the opening to the surface of the substrate. It is the process of making it move relatively along the surface.
According to a predetermined procedure, the rotating device 32 rotates the substrate, and the swing device 34 moves the droplet holding jig 10 in the radial direction of the substrate.
The droplet P moves along the surface of the substrate 5.
If the droplet is a liquid that treats the substrate, the surface of the substrate 5 is treated.

In the collecting step S50, the droplets adhering to the surface of the substrate 5 are collected.
For example, droplets adhering to the surface of the substrate 5 are sucked up using a dropper-like device.
For example, when the droplet holding jig 10 is held with the opening directed toward the surface of the substrate and the gas ejected from the opening is sprayed onto the surface of the substrate, the droplets adhering to the surface of the substrate are removed from the through hole H. Pass through and collect,
Further, for example, the droplet holding jig 10 is retracted from the surface of the substrate, and the droplets on the surface of the substrate are collected.

The measurement step S60 is a step of measuring a droplet.
For example, measure the amount of metal atoms contained in a droplet

If the substrate processing apparatus, the substrate processing method, and the droplet holding jig 10 according to the above-described embodiment are used, the following effects are exhibited.
Since the jig is held so that the droplet P adhering to the surface of the substrate 5 is surrounded by the annular opening, and the gas is blown from the opening O to the surface of the substrate, the jig is relatively moved along the surface of the substrate. The droplet P attached to the surface of the substrate 5 moves relative to the surface of the substrate 5. Therefore, if the droplet is a liquid for processing the substrate, the region where the droplet on the surface of the substrate is relatively moved can be processed.
An end face S is brought into contact with the droplet P adhering to the surface of the substrate 5 and the jig is held so as to surround the droplet P with an annular opening, and the jig is applied while blowing gas from the opening O onto the surface of the substrate 5. Since the relative movement is performed along the surface of the substrate 5, the droplet P attached to the surface of the substrate relatively moves along the surface of the substrate. As a result, if the droplet is a liquid for processing the substrate, the region where the droplet on the surface of the substrate is relatively moved can be processed.
While holding the jig so that the droplets adhering to the surface of the substrate 5 are surrounded by the C-shaped opening O and blowing the gas from the opening O to the surface of the substrate, the jig is moved relatively along the surface of the substrate. Since the opening O is positioned behind the relative movement path of the jig, the droplets adhering to the surface of the substrate relatively move along the surface of the substrate. As a result, if the droplet is a liquid for processing the substrate, the region where the droplet on the surface of the substrate is relatively moved can be processed.
The end surface S is brought into contact with the droplet attached to the surface of the substrate 5, the jig is held so that the droplet is surrounded by the C-shaped opening O, and the jig is mounted while blowing gas from the opening O onto the surface of the substrate. Since the opening O is positioned behind the locus of relative movement of the jig while relatively moving along the surface of the substrate, the droplets adhering to the surface of the substrate relatively move along the surface of the substrate. As a result, if the droplet is a liquid for processing the substrate, the region where the droplet on the surface of the substrate is relatively moved can be processed.
Holding the jig so that the droplets adhering to the surface of the substrate are surrounded by a plurality of openings arranged along a circular imaginary line, and blowing the gas ejected from the plurality of openings onto the surface of the substrate Therefore, the droplets attached to the surface of the substrate can be relatively moved along the surface of the substrate.
Further, when the gas is blown from the opening O to the surface of the substrate 5, the droplet p passes through the through hole H and drops onto the surface of the substrate, so that the droplet P passes through the inside surrounded by the opening O. The position is stabilized by being pushed by the gas attached to the surface of the substrate and ejected from the opening toward the surface of the substrate.
Further, when the gas is blown from the opening O to the surface of the substrate 5, the droplet p passes through the through hole H and collects the droplet attached to the surface of the substrate, so that it is ejected from the opening toward the surface of the substrate. It is possible to collect a droplet whose position is stabilized by being pushed by the gas, and to suppress the scattering of the droplet.
Further, when the jig is held so as to surround the droplet P adhering to the surface of the substrate 5 with the opening, the outer peripheral portion where the end N of the inner peripheral portion 13b forming the inner periphery of the opening O forms the outer periphery of the opening Since the edge of the substrate is closer to the surface of the substrate, the droplets adhering to the surface of the substrate are stabilized.
Further, when the jig is held so that the droplets adhering to the surface of the substrate 5 are surrounded by the opening, the end surface S of the end surface portion 13a that forms the inner periphery of the opening is more than the end portion of the outer peripheral portion that forms the outer periphery of the opening. Since it is close to the surface of the substrate, the droplets attached to the surface of the substrate are stabilized.
In addition, since the end surface S is brought close to the surface of the substrate with the opening O facing the surface of the substrate and the end surface is brought into contact with the droplet attached to the surface of the substrate, the droplet is sandwiched between the surface and the end surface of the substrate. .
Further, since the concave contour in which the end surface S is concave substantially coincides with the convex contour that is the degree of swelling of the free surface of the droplet P when the droplet P is attached to the surface of the substrate 5, The droplet P is stably sandwiched between the surface and the end surface of the substrate 5.
In addition, since a plurality of concave and convex shapes that are sufficiently smaller than the size of the end surface S are present on the end surface S of the end surface portion 13a, there is no uneven shape when the droplet P is sandwiched between the surface of the substrate 5 and the end surface S. Compared to the case, the contact area between the end face and the liquid increases.
Further, even when the surface of the substrate is rough, it is possible to move the droplet with the droplet attached to the surface of the substrate, and to treat the surface of the substrate with the droplet.
Further, even when the surface of the substrate and the droplet are in a hydrophilic relationship, the droplet with the droplet attached to the surface of the substrate can be moved, and the surface of the substrate can be treated with the droplet.
Further, when the liquid droplet is attached to the end face, the evaporation of the liquid droplet can be suppressed.

The present invention is not limited to the embodiments described above, and various modifications can be made without departing from the scope of the invention.
In the droplet holding jig 10 according to the first embodiment, the end surface portion has been described as forming the inner periphery of the opening O. However, the present invention is not limited to this. For example, the inner periphery portion is located away from the outer periphery of the end surface portion. And the inner periphery may form the inner periphery of the opening O.
In addition, although the description has been given of the relative movement of the droplet holding jig with respect to the substrate using the rotating device and the swinging device, the present invention is not limited to this, for example, the droplet holding device using the XY moving device. The jig may be scanned.
Further, although the liquid droplet holding jig has been described as being used in a substrate processing method for processing a substrate, the present invention is not limited to this, and can be used to hold liquid droplets attached to the substrate for other purposes.
