Definitions
- the present invention relates to an ion implanter operating in pulsed plasma mode.
- the field of the invention is that of ionic implants operating plasma immersion mode.
- the ion implantation of a substrate consists of immersing it in a plasma and polarizing it into a negative voltage, from a few tens of volts to a few tens of kilovolts (generally less than 100 kV), in order to create a electric field capable of accelerating plasma ions to the substrate.
- the penetration depth of the ions is determined by their acceleration energy. It depends on the one hand on the voltage applied to the substrate and on the other hand on the respective nature of the ions and the substrate.
- the concentration of implanted atoms depends on the dose expressed in the number of ions per cm 2 and the depth of implantation. For reasons related to the physics of plasmas, it is created, in nanoseconds after the application of the voltage, an ionic sheath around the substrate. The potential difference responsible for the acceleration of ions towards the substrate is found at the terminals of this sheath.
- I current density
- ⁇ o vacuum permitivity
- e ion charge
- V 0 potential difference across the sheath
- s thickness of the sheath.
- the thickness of the sheath is mainly related to the applied voltage, the density of the plasma and the mass of the ions.
- the equivalent impedance of the plasma which conditions the implantation current is directly proportional to the square of the sheath thickness.
- the implantation current therefore decreases very rapidly as the sheath increases.
- Ion implantation in plasma immersion mode has a number of disadvantages.
- pulsed high voltage power supplies are very expensive, often fragile and directly affect the quality of the implementation performed.
- VARIAN has proposed a pulsed plasma process known as "PLAD” (for the English word PLAsma Doping). This process is presented in two articles of the journal Surface and Coatings Technology No. 156 (2002) “Proceedings of the Vlth International Workshop on Plasma-Based Ion Implantation (PBII - 2001), Grenoble, France, 25-28 June, 2001” published by Elsevier Science BV:
- This method also consists in polarizing the substrate with a pulsed high voltage. However, the electric field created between the substrate and a ground electrode located opposite to draw the plasma. The field lines around the substrate allow acceleration and ion implantation.
- the pulsed plasma makes it possible to overcome some of the side effects described above, but the constraints associated with the use of a high-voltage pulse generator are still present.
- the characteristics of the plasma can not be separated from the bias voltage.
- the machine is not very versatile: it has a reduced range of acceleration voltage and it is always difficult to implant non-plasmagene species.
- US 5,558,718 teaches a pulsed-source ion implantation apparatus and method.
- This ion implantation apparatus is devoid of high voltage pulse generator. It uses a pulsed plasma source and a constant voltage applied to the target by a power source.
- a high capacity circuit is connected in parallel with this power source.
- This circuit which has a resistor and a capacitor in series has a number of limitations. First, it consumes a lot of energy. Then, it must be designed to be adapted to the volume of the target to be ionized. Finally, the time constant of this parallel circuit must be greater than the duration of the pulse from the generator.
- DE 195 38 903 proposes an apparatus provided with a plasma source, a substrate-carrying tray and a supply of this tray.
- This apparatus comprises a resistor disposed between the plate and the power supply; a capacitance connected to ground is connected to the common point of power and resistance.
- the resistance which is here provided to limit the arc currents generates a potential drop across its terminals. This potential drop depends on the implantation current and thus seriously disturbs the control of the acceleration voltage that is applied to the substrate holder.
- an ionic implanter comprises a pulsed plasma source, a substrate-carrying plate and a power supply connected directly between this substrate-carrying plate and the ground; in addition, it comprises a capacitor connected between the mass and said substrate-carrying plate.
- this power supply of the plate comprises a DC voltage source connected in series with a load impedance.
- the impedance is a resistance which is between 15 ⁇ s and 500 ⁇ s.
- the capacitance has a value of between 5 nF and 5 ⁇ F.
- the invention also relates to an implementation method implementing such a method comprising periodically repeating the following four phases at least:
- the supply of the tray is a source of direct current.
- the implanter comprises means for the duration of the plasma pulse emitted by the pulsed plasma source to be between
- the capacity has a value of between 5 nF and 5 ⁇ F.
- An implantation method corresponding to this second embodiment is identical to that defined above in relation to the first embodiment. Generally, these methods provide for a plasma ignition time of between 1 ⁇ s and 10 ms.
- these processes include, following the extinction phase, a waiting phase.
- the plasma has a density of 10 8 to 10 10 / cm 3 for a working pressure of 2.10 -4 4 E 5.10 3 mbar.
- the voltage used to power the tray is between -50 V and -10O kV.
- the frequency of the plasma pulses is between 1 Hz and 14 KHz.
- the substrate-holder plate is rotatable about its axis.
- the substrate-carrying plate and the pulsed plasma source of parallel axes have an adjustable offset.
- FIG. 1 represents an implanter in vertical schematic section
- - Figure 2 shows a first tray supply variant
- - Figure 3 shows a second tray supply variant
- an ion implanter IMP comprises several elements arranged inside and outside a vacuum enclosure ENV.
- ENV vacuum enclosure
- metallic elements such as Iron, Chrome, Nickel or Cobalt.
- Silicon or silicon carbide coating may also be used.
- a substrate carrier plate PPS in the form of a horizontal plane disk, movable about its vertical axis AXT 1 receives the substrate SUB to undergo ion implantation.
- a high-voltage electrical passage PET formed in the lower part of the enclosure EPS electrically connects the vertical axis of the plate AXT, and therefore the substrate holder plate PPS, to an ALT tray feed connected to the mass E.
- a capacitance C also connected to the ground E is mounted downstream of this ALT tray feed; in other words, this capacitor C is connected between the substrate holder plate PPS and the mass E.
- Pumping means PP, PS are also arranged at the lower part of the enclosure ENV.
- a primary pump PP is connected at the input to the enclosure ENV by a pipe provided with a VAk valve, and output in the open air by an exhaust pipe EXG.
- a secondary pump PS is connected at the input to the enclosure ENV by a pipe provided with a valve VAi, and output at the input of the primary pump PP by a pipe provided with a valve VAj. The pipes are not referenced.
- the upper part of the enclosure ENV receives the source body CS, cylindrical, vertical axis AXP.
- This body is quartz. It is externally surrounded, on the one hand by confinement coils BOCi, BOCj, and on the other hand by an external ANT radiofrequency antenna.
- This antenna is electrically connected, via a BAC tuning box, to a pulsed radiofrequency power supply ALP.
- the plasmagenic gas inlet ING is coaxial with the vertical axis AXP of the CS source body. This vertical axis AXP encounters the surface of the substrate holder plate PPS on which the substrate to be implanted SUB is placed.
- pulsed plasma source discharge, ICP (for Inductively Coupled Plasma), Helicon, microwave, arc.
- ICP Inductively Coupled Plasma
- Helicon Helicon
- microwave arc
- the choice of the source must make it possible to have a plasma potential close to zero. Indeed, the ion acceleration energy is the difference between the plasma potential and the potential of the substrate. The acceleration energy is then controlled only by the voltage applied to the substrate. This point becomes predominant if one wishes very low acceleration energies, lower than 500 eV, which is the case for applications in microelectronics.
- an RF source formed of a quartz tube is associated with an external radiofrequency antenna ANT and magnetic confinement coils BOCi, BOCj as specified above.
- the independence between the conditions required for the ignition of the plasma and the polarization voltage of the substrate allows a great versatility of the range of usable energies.
- the possibility of a very low bias voltage, less than 50 or 100 volts, for example, is an advantage for the manufacture of ultrafine junctions of electronic components.
- Any plasmagene species can be implanted. It is possible to start from a gaseous precursor such as N 2 , O 2 , H 2 , He, Ar, BF 3 , B 2 H 6 , AsH 3 , PH 3 , SiH 4 , C 2 H 4 , a precursor liquid such as TiCl 4 , H 2 O, or a solid precursor.
- a gaseous precursor such as N 2 , O 2 , H 2 , He, Ar, BF 3 , B 2 H 6 , AsH 3 , PH 3 , SiH 4 , C 2 H 4
- a precursor liquid such as TiCl 4 , H 2 O, or a solid precursor.
- FIG. 2 represents a tray feed module ALTi according to a first embodiment of the invention.
- the tray supply ALTi has a DC voltage source STC in series with a load impedance Z which is provided to limit the current at the beginning of the load of the capacitor C.
- This load impedance is often a resistance. It can also be an inductance whose value is a function of this capacitance C and the impedance of the plasma.
- the parameters commonly used in this mode are:
- a plasma pulse duration of between 15 ⁇ s and 500 ⁇ s
- the implantation method implementing the implanter IMP periodically comprises the repetition of the following four or five phases: a charging phase of the capacitor C (the plasma source SPL being extinguished) by the DC voltage source STC at through load impedance Z until a discharge voltage is obtained,
- a ZEP plasma extension zone consisting of a cloud of ionized gas is formed between the CS source body and the PPS substrate carrier plate.
- the particles strike the substrate to implant SUB with an energy allowing their penetration inside the substrate SUB.
- FIG. 3 represents a second preferred embodiment in which the casing of the tray feed ALT 1 connected to the mass E comprises a direct current source CC.
- a plasma pulse duration of between 15 ⁇ s and 500 ⁇ s
- the implantation method implementing in this case the implanter IMP is similar to the previous one, except for the absence of the load impedance Z.
- a current source, or capacity charger is directly used, and the charging is stopped when the desired voltage across the capacitance is reached.
- the advantage of this second mode is the elimination of the load impedance Z which is a power consumption and fragility element for the machine.
- the primary pump PP and secondary PS ensure the desired vacuum depression of the enclosure ENV after disposal of a SUB substrate on the PPS substrate holder plate.
- the bias voltage can range from zero (no limitation for low voltages) to - 100 KV. Beyond this, the risks of arcage are significant.
- the value of the capacity must be chosen according to what one wishes to achieve.
- a high capacity is necessary to obtain a substrate voltage as stable as possible during the implantation phase.
- the stored charges are much higher than the charges consumed during the implantation phase;
- a low capacity makes it possible to lower the substrate voltage during the implantation phase.
- the stored charges are lower than the charges consumed during the implantation phase, which helps the extinction of the plasma during work under high substrate tension and high pressure.
- the average current of implantation depends on the density of the plasma, the polarization voltage, the frequency and the duration of the plasma pulses. For fixed instant conditions, the current can be adjusted by adjusting the repetition period. For 50 KeV implantations, the current setting range will be 1 ⁇ A to 100mA. For implantations at 500 eV, from 1 ⁇ A to 10 mA.
- the minimum voltage value of the substrate depends on the discharge time, equivalent to the plasma ignition time, and the value of the capacitance.
- the maximum voltage value of the substrate depends on the load of the capacitor.
- FIG. 1 An additional characteristic of the implanter shown in FIG. 1 makes it possible to standardize the implantation for a large substrate.
- the substrate SUB rests on a substrate tray PPS generally discoidal and movable about its vertical axis AXT.
- the plasma diffusion will be maximum along this axis, and will have a distribution gradient with respect to this axis.
- the dose implanted in the SUB substrate will have a non-homogeneous distribution.
- the rotation of the substrate holder plate PPS makes it possible to move the SUB substrate with respect to the axis AXP of the plasma source.
- the dose implanted in the substrate SUB will have a distribution whose homogeneity will be substantially improved.
