Definitions
- the present invention relates to a method for treating an inner wall surface of a micro-vacancy.
- the depth of through-holes required for TSV is a narrow and deep hole with a aspect ratio of 10 or more (high aspect ratio hole).
- a dry etching method which has been recently employed for forming a microcircuit pattern of half micron to quarter micron, and an oxygen plasma ashing method for resist removal.
- a polymer deposited due to dry etching gas, resist, etc. is generated in the periphery of the hole to be formed and remains in and around the hole, resulting in high resistance and electrical short circuit. It causes a decrease in invited yield.
- wet cleaning is required to remove the remaining deposited polymer and clean the inside of the hole. Therefore, the expectation for the wet etching / cleaning process as before is increasing also in TSV.
- Patent Document 1 A technique has been proposed in which pressure reduction and pressurization are repeatedly performed when polycrystalline silicon for solar cells having a plurality of complicated and fine holes is cleaned using ultrasonic vibration (see Patent Document 1).
- the technique disclosed in Patent Document 1 uses ultrasonic vibration, in a high aspect ratio hole pattern such as TSV that is the subject of this case, the wall thickness of the wall surface constituting member forming the hole is Since the height of the wall is extremely high, there arises a problem that the wall surface constituting member collapses (pattern collapse) due to ultrasonic vibration. This problem becomes more prominent as the aspect ratio of the hole becomes higher and the hole pattern becomes finer.
- the present invention has been made by diligent research in view of the above points.
- the object of the present invention is to quickly treat the processing liquid into the hole even if the hole provided in the substrate to be processed is a narrow and deep hole. It is an object of the present invention to provide a hole inner wall surface processing method that can reliably perform etching and cleaning without breaking the hole pattern by entering and filling.
- One aspect of the present invention includes a surface to which a processing solution is applied and a micro vacancy having an opening on the surface, and the aspect ratio (l / r) of the micro vacancy is 5 or more or the aspect ratio Is reduced to a depressurizable processing space in which a substrate having a V / S of less than 5 and V / S (V: volume of micro-vacancy, S: area of opening) is 3 or more, and then the depressurized processing space
- the processing liquid is introduced into the micro-vacancy to treat the inner wall surface of the micro-vacancy.
- etching and cleaning can be performed reliably by the processing liquid quickly entering and filling the hole.
- FIG. 1 is a schematic explanatory view for explaining a situation in which bubbles exist in a narrow and deep hole (hole) provided in an SOI substrate and the processing liquid does not penetrate to the bottom of the hole.

- 108 is an inner wall surface (108-1, 108-2)
- 109 is an inner bottom wall surface

- the so-called aspect ratio is represented by “l / r”.
- the conditions under which the bubbles 105 are formed in the holes 104 are the surface tension, viscosity, liquid composition, surface smoothness of the side wall surface 108, wettability of the processing liquid used, and the size and aspect of “r” and “l”. There are many parameters such as ratio, and it is difficult to discuss them in general.
- the inventors first formed various holes in the SOI substrate of the structural material as shown in FIG. 1 without limiting the inner structure of the hole 104 to a cylinder, and formed bubbles by using ultrapure water as a treatment liquid. I tried to verify the trend.
- the inner structure of the hole 104 is not limited to a cylindrical shape, but is a purse shape (the lower part of the opening extends in a bag shape or a tapered shape), a rectangular shape (a square shape such as a square, rectangle, or rhombus opening), a triangular shape It was created in various sizes as hexagonal, elliptical, super-elliptical, and star-shaped.
- the SiO 2 layer 102 constituting the inner bottom wall surface 109 was etched using hydrofluoric acid and buffered hydrofluoric acid, respectively, instead of ultrapure water.
- hydrofluoric acid even when the value of “V / S” was near “3”, the formation of bubbles was relatively small (the value of 300 holes with the value of “V / S” being “3”). Among them, about 15 bubbles were formed), but in the case of buffered hydrofluoric acid, bubbles were formed at a rate of 80% (240), and etching was not sufficient. Therefore, the present inventors performed the above-mentioned verification under a reduced pressure (30 Torr) by preparing a processing chamber capable of reducing the pressure.
- the inner space of the hall is hereinafter referred to as “micro vacancy”.
- the value of “r” in the case of a structure in which the micro vacancy is not a cylinder is based on the non-cylindrical “S” by regarding the micro vacancy as a cylinder.
- “l” is a depth (maximum depth) from the position of the opening to the position of the inner wall surface of the back of the micro-vacancy.
- the effect of reduced pressure in the present invention is that the aspect ratio (l / r) is 5 or more, or the aspect ratio is less than 5 and V / S (V: volume of micro-vacancy, S: area of opening) is 3 or more. Become noticeable in the case.
- the treatment liquid is buffered hydrofluoric acid and the object to be treated is an SOI substrate, a more remarkable effect can be obtained.

- the ejection diameter and the number of the gas ejection ports 702 are designed to be a predetermined gas ejection flow rate.
- the gas jetting (blowing) flow rate from the gas jetting port 702 is determined in advance at the time of design so as not to cause a stirring action or a turbulent action in the processing chamber as much as possible by the gas jetting. It is desirable to determine the optimum value in the preliminary experiment of gas ejection.
- the degree of stirring action or turbulent action due to gas ejection depends on the gas exhaust speed, and in the present invention, preferably 0.1 to 5.0 m / sec, more preferably 0.5 to 3.0 m. / sec, optimally around 2.0 m / sec.
- N 2 gas For example, when 20 nozzle holes 702 having a diameter of 2 mm are provided on the semicircular circumference as shown in the drawing, it is desirable to flow N 2 gas into the reduced pressure processing chamber 600 at an amount of 200 cc / min. At this time, the flow rate of the N 2 gas is 2.0 m / sec.
- the treatment liquid is sufficiently deaerated beforehand in order to enhance the gas absorption ability.
- N 2 gas or atmospheric gas has been exemplified as the atmospheric gas. However, if CO 2 gas is used instead of these gases, the amount dissolved in the treatment liquid can be reduced. Since it can increase, it is preferable.
- FIG. 8 is a graph showing a saturated vapor pressure curve of water.
- the horizontal axis indicates temperature (° C.), and the vertical axis indicates pressure (Torr).
- the processing solution is introduced while reducing the pressure in the processing chamber.
- the degree of the pressure reduction is preferably set to 30 Torr in order to avoid boiling of the processing solution. If pressure is applied after supplying the treatment liquid onto the surface of the substrate to be treated under reduced pressure, even if bubbles remain in the tail hole, it is desirable because the volume of the bubble is reduced by pressurization and easily escapes from the hole. For example, when the pressure is reduced from 30 Torr to 760 Torr, the volume of the bubbles becomes about 1/25. Therefore, in the present invention, it is also a preferable aspect to reduce the pressure and supply the treatment liquid sufficiently and then pressurize. Furthermore, this decompression and pressurization may occur repeatedly.
- the technology of the present invention is not limited to TSV, and can be applied to technical fields such as MEMS as long as it requires a high aspect ratio hole. .

Abstract
Description
しかし、その基本技術の一つである露光技術の停滞により、微細化による高集積化に限界説が云われ始めている。また、基本電子素子の微細化はLSIデバイス化した際のデバイスの温度上昇や電子漏洩の潜在的問題もある。最近は、微細化に依らない高集積化の技術開発もされ始めている。その一つがLSIの3次元化(3DI:3 Dimensional Integration)の技術である。この技術の実現に必要な技術の一つが、TSV(Through Silicon Via)の技術である。この技術を用いた3D集積化LSIデバイスは、ワイヤーボンディング技術を用いるパッケージレベルの3D集積化デバイスとは異なり、集積している一つ一つのデバイス間の電気的相互接続特性の飛躍的向上も期待され、次世代の高集積化デバイスとして有力である。
