Definitions
- the invention relates to semiconductor photosensitive devices, specifically to semiconductor avalanche photodiodes with an internal signal strength.
- the proposed microchannel avalanche photodiode can be used to detect ultra-weak light pulses, up to single photons, as well as gamma quanta and infected particles as part of medical gamma tomography, radiation monitoring, and nuclear physics experiments.
- a device / 1 / including a semiconductor substrate, a matrix of semiconductor regions of the opposite type of conductivity substrate, separated from the field translucent electrode by a buffer-resistive layer with a certain conductivity.
- the avalanche amplification of photoelectrons occurs at the boundaries of the substrate with semiconductor regions. In this case, an avalanche current flows to a translucent electrode through a resistive layer located above these regions.
- the disadvantage of this device is the low quantum yield in the visible and ultraviolet regions of the spectrum due to the low transparency of both the buffer layer and highly doped semiconductor regions.
- the photoelectrons formed between the semiconductor regions do not have the ability to amplify, which leads to a decrease in the sensitivity of the device.
- a device / 2 / comprising a p-type semiconductor substrate and an p-type epitaxial layer of conductivity separated from the substrate by resistive and dielectric layers. Inside the dielectric layer, stand-alone p-type semiconductor regions are formed having an exit from the one side to the resistive layer and from the opposite side to the epitaxial layer. Highly doped p-type regions of conductivity provide localization of the avalanche process in pn junctions separated from each other by regions of the dielectric layer.
- the photosensitive layer in which photoelectrons are created is the epitaxial layer grown on the surface of foreign materials - dielectric and resistive layers. Therefore, the main disadvantages of the device are the complexity of the manufacturing technology of such epitaxial layers and a high level of dark current, leading to a deterioration in the sensitivity and signal-to-noise ratio of the device.
- the disadvantage of this device is the presence, as well as the formation during operation of 'local uncontrolled micro-breakdowns in the border zone of semiconductor regions where amplifications are made photoelectrons. The fact is that the semiconductor regions are located directly at the interface of the pn junction formed at the substrate-semiconductor layer interface.
- the semiconductor regions have a charge and current connection with each other either through the electrically neutral part of the semiconductor layer, or through the substrate, depending on their type of conductivity. That is, the device does not carry out local current limitation in certain areas where the avalanche process takes place. One or more areas with a reduced breakdown potential does not allow raising the voltage on the device in order to achieve a high level of the avalanche process over the entire area of the device. Thus, the gain of the avalanche process is limited in the device, which is an indicator of the sensitivity level of the avalanche photodiode.
- an avalanche photodiode including a semiconductor substrate and semiconductor layers with different electrophysical parameters, form at least one matrix consisting of separate solid-state regions with high conductivity, surrounded on all sides by a semiconductor material of the same type of conductivity. Solid-state regions are located between two additional semiconductor layers having increased conductivity with respect to the semiconductor layers with which they share a common interface. At the same time, at least one of the additional semiconductor layers with increased conductivity does not have a common interface with solid-state regions. Semiconductor regions are arranged along the common interface of the semiconductor layers.
- solid-state regions with increased conductivity are formed from the same material as the semiconductor layers, but with different types of conductivity, from a narrow-gap semiconductor with respect to the material of the semiconductor layers, as well as from a metal material. This leads to the formation in the device of either alternating pn junctions, or heterojunctions, or metal-semiconductor junctions in the direction perpendicular to the plane of the substrate.
- At least one two-dimensional matrix of individual potential wells located between additional semiconductor layers with increased conductivity is formed in the device.
- the formation of two or more matrices of individual solid-state regions with increased conductivity leads to a greater improvement in the sensitivity and stability of the signal amplitude of the device.
- FIG. 1 shows cross sections of a microchannel avalanche photodiode with one (A) and two (C) arrays of solid-state regions located between additional semiconductor layers with high conductivity.
- the device is made on the basis of a semiconductor substrate 1, for example, silicon p-type conductivity with a resistivity of 1 ohm * cm.
- a first additional p-type semiconductor layer 2 with a specific resistance of 0.1 Ohm * cm is formed by local diffusion doping with phosphorus.
- a p-type silicon semiconductor layer 3 is grown on the surface of the substrate by molecular epitaxy with a resistivity in the range of 1-100 Ohm * cm, forming a pn junction with a first additional semiconductor layer.
- Solid states with increased conductivity 4 are formed by ion doping of the semiconductor layer with phosphorus atoms. The doping dose is selected in the range of 5-100 ⁇ KL * cm. " After annealing of the defects at a temperature of 900 ° C, regions are formed inside the semiconductor layer — n-type conductivity islands with a specific resistance of about 0.01 Ohm * cm, surrounded on all sides by p-type semiconductor material conductivity with a resistivity in the range of 1-100 Ohm * cm.
- a second additional semiconductor layer 5 is formed with a specific resistance of about 0.01 Ohm * cm. This leads to alternating rp junctions in the device volume in a direction 6 perpendicular to the substrate plane, with alternating rn junctions located between two additional semiconductor layers with increased conductivity.
- solid-state regions with increased conductivity also form germanium or titanium clusters surrounded by silicon material.
- the dose of doping with germanium or titanium is selected above 1000 ⁇ Kl * cm. " In this case, alternating heterojunctions or metal-semiconductor transitions, respectively, or metal-semiconductor transitions are formed in the direction perpendicular to the plane the substrate.
- the transverse dimensions of the solid-state regions and the gap between them are determined by a special photomask, with which they open the windows in the photoresist, or in a special mask for local doping of the semiconductor layer.
- the ion energy during doping is selected depending on the required depth of the embedded atoms.
- known elements of the device are made, such as guard rings, or deep grooves around the working area, as well as contact electrodes.
- avalanche amplification of the photocurrent occurs only at the boundaries of solid-state regions with semiconductor layers, which are independent channels of multiplication of charge carriers coinciding in direction 6. This is due to the fact that the regions of alternating potential barriers in direction 6 are surrounded by regions p p - junction, located in direction 7.
- a voltage with a polarity corresponding to lunch is applied to the upper electrode of the semiconductor layer eniyu semiconductor substrate from the main carriers.
- the average transition in the multiplication channel is shifted in the forward direction, and the two external transitions - in the opposite direction.
- the regions of the pn-junction located between the multiplication channels are also shifted in the opposite direction.
- the first additional semiconductor layer with increased conductivity limits the propagation of the electric field into the substrate, thereby reducing the dark generation current and achieving an avalanche process only in the working area of the device.
- the second additional semiconductor layer with increased conductivity limits the electric field from the outside and ensures uniformity of potential along the photosensitive surface of the device. As a result of this, a form of potential distribution inside the device is achieved that facilitates the collection of photoelectrons formed in the upper photosensitive semiconductor layer to potential micro-wells formed by solid-state regions.
- the photoelectrons are amplified in the first transition from the top of the multiplication channel, and the next transition, shifted in the forward direction, acts as a potential well with a depth of about 0.5-1 V, in which the multiplied electrons are collected.
- the accumulation of electrons in the mentioned potential well during a few nanoseconds leads to a sharp decrease in the electric field in the avalanche region (i.e., in the near-boundary region of the first transition), and as a result, the avalanche process in this multiplication channel stops. Then, within a few tens of nanoseconds after the end of the avalanche process, the accumulated electrons go into the substrate, due to the sufficient leakage of the third transition.
- avalanche amplification of photoelectrons is carried out in independent multiplication channels, not having a charge connection with each other. This improves stability and increases the sensitivity of the avalanche photodiode.
