Description
Electrical Isolation of Regions within Semiconductor
Bodies
The present invention relates to the electrical isolation of regions within a body of a semiconductor substance as a step in the production of micro electronic devices.
In order to prqduce micro electronic devices it is necessary to isolate adjacent elements of the electrical circuit concerned and to provide isolation between active devices and underlying substrate material. It has been shown that this can be done by producing one or more buried layers of high-resistivity or dielectric material within a silicon substrate body by implanting sufficient ions of oxygen or nitrogen to create a continuous layer of silicon oxide or nitride where the ions come to rest in the silicon. However, the ion doses required are very high G1018 ions cm~2) and the process is a difficult one to carry out economically due to the need for high fluxes of ions at energies of 150-200 KeV. It is desirable therefore to find alternative techniques that can be more attractive economically.
It is known that when high doses ( > 10l7 ions cm~2) of inert gas ions are implanted into a body of silicon, bubbles of gas are formed within the silicon. If the silicon is then subjected to a post-implantation anneal, there is a tendency both for the bubbles to migrate through the silicon and for the inert gas to diffuse through the silicon and escape from the surface of the silicon so leaving voids in the silicon. It has been found, furthermore, that if oxygen is implanted into the silicon after the inert gas, then, either at the time of bombardment or during a subsequent anneal, it will migrate to the bubbles, associate with them and stop their migration when the silicon is annealed.
According to the present invention there is provided a process for producing a buried dielectric or highresistivity layer within a body of semiconductor material comprising the operations of implanting ions of hydrogen or an inert gas into the body at an energy and dose such as to form a layer of discrete bubbles and/or voids within the body of semiconductor material and subsequently implanting ions of oxygen or nitrogen into the semiconductor material at an energy and dose such as initially to stabilise the bubbles and/or voids within the semiconductor material and then form a layer of oxide or nitride of the semiconductor material bridging the gaps between the said bubbles and/or voids.
Suitable ion doses and energies for the formation of the bubbles and/or voids are at least 1014 ions cm~2 and the range 10-100 KeV, respectively. The ion energy required depends on the depth at which it is desired to produce the buried layer of dielectric or high-resistivity material. It is to be noted that the implantation energy required to produce any given penetration for hydrogen is about half that required for helium. Also if hydrogen is implanted to form the bubbles or voids, then the implantation temperature should be kept below about 7000K.
Suitable ion doses for the implantation of the oxygen or nitrogen are at least 1014 ions cm 2 The energy required is about twice that for helium ions and five times that required for hydrogen.
Preferably the semiconductor material is silicon.
The invention will now be described by way of example with reference to the accompanying drawing which illustrates the steps involved in producing a buried dielectric layer by a process embodying the invention.
Referring to the drawing, a body 1 of single crystal silicon is subjected to bombardment with a beam 2 of helium ions at an energy of about 75 KeV until a dose of about 1015 ions cm~2 is implanted. The temperature of the body 1 of silicon is maintained at about 6000K so that recrystallisation of the surface region 3 of the body 1 of silicon occurs continuously as the implanted helium ions pass through it. As a result of this bombardment an array of buried helium-filled bubbles 4 is formed as shown at (a) in the accompanying drawing.
The body 1 of silicon is then subjected to further bombardment with a beam 5 of ions of oxygen having an energy of 200 KeV until a dose of about 1015 ions cm 2 has been implanted. This time the temperature of the body 1 of silicon is maintained at between 800 and 9000K so as to facilitate the migration of the oxygen through the crystal lattice to the surfaces of the array of bubbles and/or voids 4. (Voids are now present because some of the helium will have diffused out of the bubbles as a result of the heating of the body 1 of silicon). Also, a layer 6 of silicon oxide is formed which bridges the gaps between the bubbles and/or voids 4, thus providing a continuous buried dielectric layer 7, as shown at (b) in the accompanying drawing.
Finally, the body 1 of silicon is annealed in an inert environment such as dry nitrogen in order to stablilise the structure and to remove any residual strain and/or disorder which may be present in the region of the body 1 of silicon above the buried dielectric layer 7.
If desired, the helium ions may be replaced by hydrogen ions and the oxygen ions by nitrogen ions. If the helium is replaced by hydrogen, then although the ion dose remains about the same, the energy required for a given depth of penetration is reduced by a factor of 2. The temperature of the body 1 of silicon needs to be reduced to about 5000K. The implantation energy and dose of the oxygen or nitrogen remains the same as before.
It should be noted that there is an upper limit to the ion dose of the hydrogen or helium arising from the need to prevent the bubbles and/or voids from being so densely packed that they may coalesce to form a continuous defect which will allow the upper region of silicon to become detached. This ion dose varies with temperature but in general is above 1018 ions cm' 2 Also, if required the ion implantations can be carried out through masks which define specific areas of the body of silicon which require to be provided with buried isolation.
As this practice is standard in the art of micro electronic device production it is not thought necessary to describe such a variation of the process according to the invention, specifically.
The invention is not restricted to the details of the foregoing example. For instance, the process might also be applied to other semiconducting materials, such as germanium, gallium arsenide, or layered structures of more than one semiconducting material, for the purpose of providing buried isolation.
