Abstract
The performance of semiconductor devices having p-n junctions is often impaired by current leakage across the junction at the surface of the device where the p-n junction is exposed. Coating the junction with a conventional insulator, such as silicon, aluminium or titanium oxide is not very successful for reducing this leakage and whilst nitride and oxide layers deposited on InP and InGaAsP semiconductors make good insulators, charge accumulation at the oxide/ semiconductor interface can cause adverse effects on performance. It is thus proposed to use the group III-V ternary compound AlAsSb or AlGaAsSb as a semi-insulating passivating medium (22) for InP and InGaAsP devices and as an insulating material in MIS devices. <IMAGE>
Description
SPECIFICATION
Coatings for semiconductor devices
This invention relates to coatings for semiconductor devices and particularly to coatings for the insulation and passivation of semiconductor devices.
The performance of semiconductor devices having p-n junctions is often impaired because leakage currents shunt the junction at the surface of the device where p-n junction(s) are exposed.
The leakage path is probably due to minority carrier recombination at surface states and conduction due to surface contaminants. Coating with conventional insulators such as silicon oxides, silicon nitride, boron nitride, Al2O3, Ti2O3, etc. is normally only marginally successful in suppressing and passivating against such current leakage.
Nitride and oxide layers deposited on InP and
InGaAsP semiconductors make good insulators but charge accumulation at the oxide/semiconductor interface can cause drifting and other adverse effects.
It is an object of the present invention therefore to provide a coating for a semiconductor which will reduce or prevent such leakage currents without having adverse effects on the performance of the semiconductor.
According to the present invention a coating for a semiconductor comprises a layer of a compound of at least one Group Ill element selected from aluminium and gallium and at least one Group V element selected from arsenic and antimony.
Preferably the compound is a ternary compound.
Thus, the compound may be aluminium arsenide antimonide or gallium arsenide antimonide. Alternatively the compound may be quaternary and comprise aluminium gallium arsenide antimonide.
Preferably the compound has a formula of AlAs1~xSbx whereby the composition can be adjusted to deposit a lattice matched layer of the compound.
Thus, for example, if x=0.35 a lattice matched epitaxial layer of Also 65 So 35 can be deposited on to an InP or an InGaAsP device.
The material with x=0.35 will have an indirect bandgap around 1.95eV and the undoped material will have a high resistivity. The material can be deposited either by established liquid phase epitaxial growth techniques, by Molecular
Beam Epitaxy or by Metallorganic Chemical
Vapour Deposition techniques.
The coating with epitaxial near lattice matched
AlAsSb will make the device effectively more planar, it will cause saturation of surface dangling bonds and therefore reduction of surface states and will protect the exposed junctions from contamination.
Embodiments of the invention will now be described by way of example only with reference to the accompanying drawings in which
Figure 1 is a cross-sectional view through an
InGaAs/lnP p-i-n photodiode having a passivating coating in accordance with the invention
Figure 2 is a cross-sectional view through an
InP or InGaAs/lnP metal insulator semiconductor field effect transistor having a semi-insulating coating in accordance with the invention and
Figure 3 is a cross-sectional view through an
AlAsSb/GalnAsP double heterostructure multilayer for light sources and detectors.
The coating can be used to suppress the current leakage which shunts the device p-n junction by passivating the device against surface contamination and to form an insulating or semiinsulating layer on the surface of the device which would not tend to become charged.
An illustration of the former use is shown in
Figure 1. This shows a laser layer structure comprising an InP substrate 10 having an n type
InP buffer layer 12. On the buffer layer is arranged an InGaAs active laser layer 14, a p type InP layer 16 and a metal contact 18. Further metal contacts 20 are arranged on the opposite side or rear of the substate 10. Extending between the substrate 10 and the edges of the metal contact 18 is a passivating infil 22 of AlAsSb which also covers the sides of the layer 12, 14 and 16. The infil 22 suppresses current leakage from the p-n junction and forms a heterojunction barrier for the laser. This provides heterobarriers of around 1 eV compared to 0.35 eV for a conventional device.
The infil of AlAsSb can be used in both stripe and buried heterostructure laser geometries.
The field effect transistor shown in Figure 2 comprises a semi-insulating InP substrate 24 and an InP or InGaAs n type channel layer 26.
Metallised areas 28 and 30 formed on this layer provide drain and source contacts respectively and between these areas is arranged an AISbAs semi-insulating layer 32. A gate 34 is formed on the layer 32 by metallising a further area. The device shown in Figure 3 is suitable for a light source or detector and consists of an n type InP substrate 36, an n type AlAsSb layer 38, an active
GalnAsP layer 40, a p type AlAsSb layer 42 and a p type GalnAs layer 44.
