Definitions
- the present invention relates to a method for bonding a first bonding surface of a first, consisting of a first material
- the goal in the permanent or irreversible bonding of solid substrates is to create as strong and, in particular, irrevocable connection, ie a high bonding force, between the two contact surfaces of the solid substrates.
- irrevocable connection ie a high bonding force
- TSVs Through Silicon Vias
- the bonding process must therefore be designed so that active components, such as transistors, which are already present on the structure wafers, are neither affected nor damaged during the processing.
- Compatibility criteria include above all the purity of certain chemical elements (especially in CMOS structures), mechanical strength, especially by thermal stresses.
- recrystallization is meant a structure formation by
- Grain growth The prerequisite for such grain growth are high degrees of deformation, which increase the dislocation density of a material, thus bringing the material into an energetically metastable state, which leads to grain formation when a critical temperature is exceeded.
- massive transformation processes such as rolling, forging, are predominantly used to achieve high degrees of dislocation , Deep drawing twisting, scissors, etc. used.
- the object of the present invention is therefore to provide a method and a device or a chip tool, with which the bonding of two solid substrates for the substrates and any
- Structures on the substrates gentler and more effective executable.
- the basic idea of the present invention is to planarize at least one of the two bond surfaces, preferably both bond surfaces, before contacting in such a way that the surface roughness O of the
- Bond surface (s) is minimized to pass through the basic surfaces
- Recrystallization after contacting optimal to weld or to bond is intended to dispense with chemical-mechanical polishing processes (CMP).
- CMP chemical-mechanical polishing processes
- a metastable microstructure is produced on the bonding surface in order to obtain a high dislocation density and / or an amorphous layer on the bonding surface. Due to the high dislocation density and / or the amorphous layer, the recrystallization process is promoted and / or accelerated. In particular, a smooth surface is provided (reduction of the surface roughness).
- amorphous areas near the surface are provided for improved bonding of the two surfaces.
- Materials are used in industry mainly by vapor deposition of a material on cooled substrates, by bombardment of ions or Irradiation, by extremely strong mechanical deformation, etc.
- the invention disclosed herein discloses a possibility of producing existing near-surface regions with high dislocation densities and / or amorphous regions.
- planarization and generation of the metastable structure are accomplished by a machining process.
- Solid substrates of the following materials are suitable as solid substrates according to the invention:
- Ill-V GaP, GaAs, InP, InSb, InAs, GaSb, GaN, A1N, InN, Al x Ga ,.
- FIGS. 3a and 3b schematically show the influence of the tool speed (FIG. 3a) and the temperature (FIG. 3b) on the breaking strength (T f ) and the sliding resistance (Gf) at
- the breaking strength T f is the resistance that the material opposes to a force which would like to separate the material without plastic deformation, ie, ideally brittle.
- the slip resistance G f is the resistance that the material opposes to a force, more precisely a thrust force, which would like to plastically deform the material.
- the mechanisms of plastic Deformation is mainly the mechanical
- FIGS. 3a and 3b show schematic courses of the sliding and separating breaking strength as a function of the temperature and the tool speed for metals.
- V k a critical velocity empirically determined in each case for the material (in particular considering the thickness)
- the sliding breaking strength Gr has lower values than the breaking strength T f.
- the material is below the critical at tool speeds
- Gleitbruchfesttechniken additionally depend on the material temperature (Figure 3b). At temperatures above the critical temperature Tk, the material failure takes place mainly by sliding, where against below the critical temperature Tk the material fails mainly due to brittle fracture (ie separation fracture). Thus, according to the invention, the "freezing" of the dislocations takes place at low temperatures Dislocation movement as a material-physical process is explicitly dependent on the temperature. The lower the temperature, the lower the dislocation mobility and the harder it is to move the dislocations of the solid substrates. It can be seen from FIGS. 3 a and 3 b that a metal generally breaks brittle the higher the tool speed and the lower the temperature. Around
- Curves (1) require a very high Kerbschl agaille over the entire temperature range and are mainly by
- the low impact energy is due to the fact that any existing or formed crack only needs to apply the energy necessary to continue growth, hence the binding energy between the atoms. In contrast to the deformation fractures, no energy is consumed for dislocation and / or dislocation movement. Therefore, the impact energy is lower. Furthermore, there are materials whose
- Notch energy has a curve (3). This curve shows a clear transition from deformation fracture to separation fracture with decreasing temperature. For materials with this physical
- Recrystallization temperatures are above or below these values.
- a crucial factor influencing the recrystallization temperature is the contamination of alloying additives. So is the example
- Recrystallization temperature of electrol yti sch Taiwan schi edenem copper which is naturally rather impure, but at about 200 ° C.
- Deposition of copper by electrolysis is always associated with organic additives, ions and impurities. Separated copper from CVD and / or PVD processes, however, is highly pure.
- the second condition for recrystallization is an energetic metastable state. This is inventively by a high
- Dislocation density and / or produced by an amorphous-crystalline structure and / or by quasi-crystalline structure Preferably, an amorphous matrix is provided in which partially crystalline phases and / or quasicrystalline phases occur, most preferably micro- and / or nanocrystals with a high dislocation density. Also conceivable is any combination of crystals, quasicrystals and amorphous structural components in any desired volume ratio. In order to clarify the further course of the text, one will primarily speak of crystalline-amorphous structures.
- the contacting of the solid substrates is carried out.
- any unwanted reactions such as oxidation of the functional layer or the surfaces of the solid substrates are minimized.
- the bonding surfaces according to the invention are applied to a
- R q squared roughness
- a seamless transition is understood to mean a polycrystalline structure that extends from one side of the bonded wafer to the other without interrupting the grain structure.
- the generation of such a seamless transition is carried out in particular by recrystallization in the described, in particular empiri sch based on the material of the solid substrates and their dimensions determined parameters.
- Recrystallization is due to a high dislocation density and a
- Recrystallization temperature is insufficient for thermal movement to cause dislocations of the dislocation network to self-start to slide due to the repulsive strain fields.
- the dislocations are virtually "frozen.”
- the temperature exceeds the recrystallization temperature the thermal movement, the dislocation density, is sufficient
- a method according to the invention has the following steps for bonding a first bonding surface of a first solid substrate comprising a first material to a second bonding surface of a second solid substrate comprising a second material, in particular the following sequence:
- 1 ⁇ preferably less than 1 00 nm, most preferably less than 10 nm, most preferably less than 1 nm,
- a corresponding device according to the invention in particular in its most general embodiment, has the following features:
- a cutting tool for machining the first and / or second bonding surfaces for generating a metastable len structure in the at least near-surface region in particular in a Speed v s below a critical speed Vk and at a temperature T s above a critical temperature T k , and up to a surface roughness O of less than 1 ⁇ , preferably less than 100 nm, most preferably less than 10 nm, with the utmost Preference less than 1 nm,
- Solid state substrates for forming a permanent bond caused at least predominantly by recrystallization
- the first and the second material are selected identically. As a result, the recrystallization is favored.
- the first and / or the second material are metallic.
- the present invention is particularly suitable for metallic materials, so that with such an optimal result can be achieved. As far as the formation of the permanent bond at a bonding temperature T B is greater than the critical temperature T k , the formation of the permanent bond is accelerated.
- the machining with the cutting tool takes place in such a way that an amorphous layer and / or an amorphous layer is applied to the first and / or second bonding surface
- Processing speed and temperature are in particular dependent on the material of the solid substrates and their dimensions, in particular their thickness. Suitable parameters can, in particular material-specific, be determined empirically.
- a second processing of the first and / or second bonding surfaces with one, in particular the same, chip tool at a speed v 0 above the critical speed Vk, in particular at a temperature T 0 below the critical temperature T k for reducing the surface roughness O is less than 100 nm, preferably less than 10 nm, more preferably less than 1 nm, most preferably less than 0, 1 nm.
- the fracture fraction is also often referred to in the literature as brittle fracture.
- Intergranular separation fracture the crack runs along the grain boundaries of a grain.
- transcrystalline separation fracture the crack runs transversely through the grain.
- the microstructure of the materials used preferably has grains in the nanometer range, and therefore it has only a roughness in the case of an intercrystalline separation fracture
- Nanometer range can give.
- the invention thus relates to a method by which the recrystallization of a material (material of the solid substrates) at a comparatively low temperature in near-surface regions of the bonding surface by the generation of a metastable state of energy in the
- a metastable energy state is generated only in near-surface regions of the bonding surfaces.
- a cutting tool in particular consisting of several tools, is used, which is or is capable of, by means of frequency, cutting speed,
- Tool geometry, tool temperature and / or cutting insert anglejustste len a specific microstructure on the bonding surface. It is particularly advantageous if the tool parameters and environmental parameters are selected such that the near-surface region or the bonding surfaces have a higher dislocation density after the tool has passed.
- the microstructure is preferably coarser.
- a coarse-grained structure has a very low thermal and especially electrical resistance.
- monocrystalline microstructure are particularly suitable for electrically conductive connections. Since the industry prefers the method according to the invention, but not exclusively for the production of
- Interconnects will use as electrically conductive connections, therefore, the lowest possible electrical resistance and thus a possible coarse-grained structure is usually desirable.
- a fine-grained microstructure is preferred, since this is a higher one especially under thermal cycling
- Bond surface or the near-surface region after the first processing, ie the passage of the tool consists of an amorphous layer in which crystalline regions are provided, which preferably have a very high dislocation density.
- the thickness of the amorphous layer is determined in particular by the - empirically determined - tool speed.
- Another elementary aspect of the invention is the recrystallization over the contact plane or over the near-surface layer of the contact (in particular in the area of the surface roughness O). This is inventively achieved or optimized in particular by the surface roughness O comparatively low
- the surface roughness O can be minimized.
- the minimum surface roughness O will be associated with a high tool speed and a low temperature, because parting surfaces are smoother than surfaces that have undergone a plastic deformation process.
- the lower surface roughness does not physically change the recrystallization, ie the structural transformation, it allows the newly formed grains, the
- the recrystallization temperatures depend on the material used of the solid substrates and this is particularly dependent on the dislocation density of the material. For the purposes of the present
- Recrystallization temperature assumed (homologous temperature of 0.5). According to the invention, it is conceivable to reduce the recrystallization temperature to a minimum by the targeted addition of additives, in particular alloying elements or targeted contamination, with the advantage of using highly pure metals.
- the empirical determination of material-specific parameters can be carried out, in particular by impact strength measurement on bulk materials. Furthermore, the empirical determination of parameters according to the invention can be determined on the basis of the actual design and test series with the device according to the invention. This is particularly preferred because a transmission of the default values of
