Definitions
- the invention relates to a susceptor for supporting a substrate within a vacuum process chamber, comprising a flat surface for placing the substrate thereon such that the substrate is in thermally conductive contact with the surface. More precisely, the invention relates to establishing a highly uniform substrate temperature on large area substrate surfaces.
- the invention describes a high uniformity heating system for the substrate having preferably a non-circular shape in a vacuum environment. This heating system can be applied to many coating or substrate treatment processes working at temperatures higher than room temperature.
- Thin film deposition or coating processes are well known in the art. Since then, deposition uniformity is an important criterion, especially in the production of large area coatings.
- layer properties realized on small scale need to be extended to large area substrates.
- a typical example is the IC industry, where several thin film layers are adjusted to each other. This adjustment needs to be maintained over the whole substrate area, which requires good uniformity on all involved layers in all their critical properties over the whole wafer.
- Thin film solar cell application is a similar example.
- the cell properties allowing high efficiency need to be applied over the whole integrated module. Areas with properties “out of specification” will deteriorate individual cells. Such a cell will exhibit a lower efficiency causing a higher resistance in the serial connection. As a consequence, areas of bad cell properties reduce the overall performance of the complete solar module.
- Prior art systems use a hot plate or a susceptor, whereby the hot plate respectively the susceptor means an essentially flat surface fit for accommodating a substrate and transferring heat to the substrate such that a.m. requirements in terms of uniform heat distribution are being met. That surface can be established as one surface of a plate having at least the size of the substrate area to be heated or temperature controlled.
- a hot plate may contain several independent heating zones with different heat inputs.
- the perimeter of the hot plate i.e. edges and corners, needs to be heated to a higher temperature than the centre to overcome the heat losses due to higher thermal radiation of the hot plate and the substrate at the periphery.
- a solution known in the art for heating is attaching electrical heating elements to the hot plate or to integrate the heating elements such as a resistance heating.
- a more sophisticated method of controlling the temperature on a hot plate is to observe the substrate heat uniformity by thermo-camera measurements.
- the heating zones are tuned accordingly, so that a uniform temperature reading is seen over the whole substrate. That approach allows the generation of a uniform temperature profile without influencing other parameters.
- the temperature of the hot plate can be tuned after investigating layer properties resulting from a manufacturing process using the hot plate.
- This method is widely used in commissioning of vacuum equipment.
- the coating property uniformity is not only influenced by the temperature but also by the gas flow and geometry of the deposition equipment. So flow non-uniformities may be compensated by the temperature tuning of the hot plate.
- Heating rectangular substrates is challenging, as, in particular, the substrate corners and edges are more strongly affected by thermal radiation to the surrounding cooler chamber. One would expect that this can easily be compensated by increasing the heat input into such regions. However, it is difficult to get sufficient heat into the hotplate corner region by simply wiring a denser heating pattern, of resistor heating elements, e. g., compared to the other parts of the hot plate. Changing such heating patterns means substantial, i.e. mechanical, changes of the hot plate which is expensive and time-consuming. One solution to this problem would be to individually heat the corner zones and thus electrically adjusting the heat emission into the hot plate. This approach has turned out to be impractical.
- susceptor or hot plate materials are conductive materials and they should conduct the heat of the heating wires or heating elements to the substrate as efficiently possible.
- Al, Cu or Carbon are commonly used as susceptor material.
- Less conductive materials would require a more dense wiring of heating elements to get uniform heating.
- the well-conducting material is basically smearing out local heat maxima generated by the heater wire location. This effect however is counterproductive on the edges and the corners of the susceptor. There strong heat maxima are needed to compensate the edge and corner heat losses of the substrate. Simply overheating the edge and corner zones will increase the temperature of the centre heat zone as well.
- FIG. 1 An example can demonstrate this effect, as shown in Figure 1 and 2.
- a susceptor 1 containing four independently operating and controlled heating wires 2, 3, 4 is used. All heating wires 2, 3, 4 are mounted on a one-piece hot plate, i.e. on the substrate 1.
- the four heating wires 2, 3, 4 are forming 4 different zones 5, 6, 7.
- the first zone 5 is the centre zone heating most of the substrate 9.
- the second zone 6 is an optional intermediate zone equalizing the temperature differences between the first zone 5 and the second zone 6.
- the third zone 7 is heating the substrate 9 edge.
- the heating wires 2, 3, 4 are mounted from below the hot plate 1 as indicated in Figure 2, wherein the second zone 6 has been omitted.
- the centre zone 5 has a wider spacing in wiring 2 than the edge zone 7.
- the rim heater zone 8 with heat element 4 is arranged on top of the hot plate 9, but recessed from the heating surface. It is secured by an edge bar 10 on the hot plate 9 and protected from contamination by the CVD process.
- the substrate 9 is slightly larger than the susceptor 1 surface so that the edge of the substrate 9 is overlapping and thus heated by the edge bar 10.
- the following table shows the temperatures set by the operator and the temperature actually reached by the hot plate 9 as indicated by thermocouples attached within the specific zones 5, 6, 7, 8.
- Operator set point Actual temperature reading First zone 5 180 °C 181 °C Second zone 6 185 °C 195 °C Third zone 7 195 °C 195 °C Rim zone 8 210 °C 210 °C
- the second zone 6 is overheated above its target temperature, due to the influence of the temperature settings of the first zone 5 and the third zone 7. Accurate heating of the second zone 6 area is not possible due to the cross talk of the heating zones 5, 6, 7, 8.
- edge and rim zone 8 temperatures well above the center zone’s 5 temperature, since otherwise the substrate 9 edge temperature is too low to allow uniform growth.
- a solution to the problem of crosstalk of heat between different zones 5, 6, 7, 8 would be the manufacturing of the susceptor 1 from several thermally isolated pieces. It could be foreseen that a centre zone plate 5 is installed surrounded by a separate rim zone 8 frame which is also independently heated.
- this solution has several drawbacks. First, it is not manufactured from one piece of susceptor 1 material. This makes the manufacturing difficult and expensive since the tolerances between the different susceptor 1 plates have to be low enough to allow the uniform substrate 9 heating. Secondly, it is very difficult to have a smooth temperature profile over the gaps between centre zone 5 and rim zone 8. Depending on the substrate 9 thickness a desirable smearing between the two zones 5, 8 may not be sufficient to compensate the heat losses due to the interface of centre zone 5 and rim zone 8.
- the object is achieved by a susceptor for supporting a substrate within a vacuum process chamber, comprising a flat surface for placing the substrate thereon such that the substrate is in thermally conductive contact with the surface, whereby the susceptor comprises at least three adjacent zones, an outer zone, a middle zone and an inner zone, the zones arranged concentrically around each other and extending along the surface, the outer zone completely surrounds the middle zone and the middle zone completely surrounds the inner zone, the inner zone comprises at least one inner heating element affecting the inner zone, the outer zone comprises at least one outer heating element affecting the outer zone, and the middle zone exhibits a maximal thickness that is smaller than the minimal thickness of the inner zone and smaller than the minimal thickness of the outer zone, each thickness extending perpendicular to the surface.
