Abstract

Semiconductor devices, and in particular solar cells or other photosensitive devices, are fabricated from amorphous material which comprises at least one elemental semiconductor and at least one halogen. Specific examples are elemental germanium or a germanium/silicon compound. One method of deposition is plasma aided chemical vapour deposition from a mixture of gases, e.g. germane or germane and silicon with a halogen bearing gas.

Description

SPECIFICATION Semiconductor devices This invention relates to the fabrication of semiconductor devices, and finds particular application in solar cells and other photosensitive devices.

The use of plasma aided chemical vapour deposition techniques (also known as r.f. glow discharge) enables both elemental and alloyed semi-conductor materials to be deposited in amorphous states on suitable substrates. The choice of semiconductor materials depends on the particular application. For example, in solar cells it is necessary to match the absorption characteristics of the material to the solar spectrum whilst providing a satisfactory energy band gap to make devices with the hightest possible efficiency.

According to the present invention there is provided a methof of fabricating semiconductor devices including the step of depositing a layer of amorphous material being a alloy of at least one elemental semiconductor and at least one halogen on a conducting substrate.

In a preferred example of the invention the elemental semiconductor is germanium.

In another example of the invention the semiconductor material is a alloy of elemental germanium and silicon.

Germanium and germanium/silicon alloys deposited by glow discharge from germane or germane/silane mixtures (and hence including hydrogen), even with rather small germanium content, show negligible photo-conductivity compared with pure silicon. This can be interpreted in terms of the Ge-H bond being weak compared with the Si-H bond, with the result that dangling bonds on germanium atoms are not stably hydrogenated in amorphous germanium and its alloys, and with the further consequence that these materials have a large density of states in the gap. It would therefore not be possible to prepare solar cells from them even though their absorption edge could be well matched to the solar spectrum.Clearly this situation would alter if a stronger bonding element, such as a halogen, were used to satisfy germanium dangling bonds. (Even the Ge-l bond is far more stable than Ge-H).

The deposition of amorphous germanium or germanium/silicon alloys from germane or a germane/silane mixture is readily accom plished by plasma aided chemical vapour de position. The introduction of a further gas, bearing a halogen, for example fluorine, enables a halogenated amorphous semiconductor to be deposited.

Other deposition techniques, such as sputtering, for example in a hydrogen/halogen mixture, may also be used. The proportions of the starting materials are chosen to give absorption characteristics tailored to the wave lengths of the incident radiation.

The invention is not limited to photosensitive devices since, with a p-n junction region in the deposited material rectification is present. Used in a non-optical context the halogenated amorphous material can be fabricated as a semiconductor diode.

The term "alloy" refers in this specification to an intimate mixture of the elements concerned deposited by the method given and may or may not have chemical bonding.
