It is about. Background art
- nitride semiconductors are characterized by having a large band gap, and are therefore used for various optoelectronic devices.
- the surface of a P-type nitride semiconductor processed by etching or the like is damaged by the processing. This damage is due to the n-type conductivity, so that even if an ohmic electrode is formed on the surface of the processed p-type nitride semiconductor, good current-voltage (IV) characteristics cannot be obtained (for example, see Non-Patent Document 1; T. Makimoto, K. Kumakura, and N. Kobayashi, Journal of Crystal Growth 221, P. 350-355 (2000), and Non-Patent Document 2; T. Makimoto, K. Kumakura, and N. Kobayashi, phys. S tat. Sol.

- a p-type electrode (base electrode) 25 is formed on the exposed base layer 22.
- an n-type electrode 26 is formed on the emitter layer 21 and the exposed n-type sub-collector layer 24.
- the emitter layer 21 is removed by etching to expose the surface of the base layer 22 in order to form the base electrode 25.
- a base electrode 25 is formed on the exposed surface of the base layer 22. Since the exposed surface of the base layer 22 is subjected to etching damage, the base electrode when the base layer 22 is p-type GaN does not exhibit good I-V characteristics. Furthermore, the fabricated HBT does not exhibit good common-emitter IV characteristics.
- the first method to reduce the effects of damage is to regrow the P-type GaN on the damaged surface (eg, Non-Patent Document 3; LS McCarthy, P. Kozodoy, MJW Rodwel 1 , SP DenBaars, UK Mishra, IEEE Electron Device Letters, Vol.20, No.6, P.277-279 (1999), and Non-Patent Document 4; BS She 11 on, DJH Lambert, Jian Jang Huang , MMWong, U.

- Non-Patent Document 3 the rising voltage in the emitter-grounded IV characteristic is 4 V or more. Furthermore, in Non-Patent Document 4 described above, it is impossible to measure the rising voltage because the reported common-emitter I-V characteristic has a large leakage current.
- regrowth of p-type GaN did not significantly improve HBT properties.
- P-type GaN which is a typical example of a p-type nitride semiconductor
- the properties of HBT were improved because the processing damage at the regrowth interface could not be repaired. Probably not. This indicates that regrown materials are important for producing good HBT.

- the current gain in the emitter-to-I-V characteristic was 5 or less and the rise voltage was 3.5 V or more, and good HBT characteristics were obtained. Absent. In this case as well, it is considered that the HBT characteristics were not improved because the damage existing between the p-type GaN base layer and the p-type GaAs growth layer could not be repaired. Can be This means that simply increasing the hole concentration in the layer regrown on the processed P-type GaN, This indicates that good HBTs cannot be produced.

- the thickness of the InGaN thick film used for the measurement is about 100 to 200 nm.
- the ⁇ -type InG aN is used for the base layer 2, but the lattice constant difference from G aN increases when the In composition of the p-type In G aN increases. Therefore, the defect density increases. As a result, the minority carrier life is shortened, and the current gain may be reduced. Therefore, the In composition of the P-type InGaN in this example used a relatively small value of 7%. On the other hand, when the In composition is small, the influence of processing damage increases (for example, see Non-Patent Document 1), so the relationship between current gain and processing damage is considered to be in a trade-off relation.
- the In composition of the P-type InGaN base layer 2 is about 5% to 30%, and the In composition of the p-type nitride semiconductor layer 8 is p-type InGa It is desirable that the composition be higher than the In composition of the N base layer 2.
- a spike occurs between the base layer 2 and the collector layer 4 due to conduction band discontinuity. This spike prevents electrons injected from the emitter layer 1 into the base layer .. 2 from traveling to the collector layer 4 and thus reduces the current gain.
- a graded In GaN layer 3 in which the In composition was gradually changed was inserted.
- the HBT layer structure shown in FIG. 2 was processed by dry etching (reactive ion etching) using chlorine gas to expose the surface of the base layer 2 and the surface of the sub-collector layer 5.

Thereafter, the Si 2 mask 12 was removed by HF, and each electrode (base electrode 9, collector electrode 10, and emitter electrode 11) was formed by electron beam evaporation.

Kumakura, T. Makimoto and N. Kobayashi, Applied Physics Letters, Vol. 79, No. 16, pp. 2588-2590 (2001 ))).
- the thin p-type InGaN layer serves to reduce the contact resistance with metal, and there is no description of the essential part of the present invention.
- the thickness regrown on the p-type InGaN layer 2 It should be noted that regrowth of a p-type InGaN layer 17 having a thickness of 100 nm and an In composition of 20% is an essential part of the present invention.
- the Mg concentration of the 20% p-type InGaN external base layer 17 is preferably higher than that of the 7% p-type InGaN base layer 2. On the other hand, it has been found that when the Mg concentration is too high, the hole carrier concentration decreases. From the above, M g concentration, 1 X 1 0 1 9 c m- 3 force is desirably between et 2 X 1 0 2 Q cm- 3 . In addition, if the thickness of the 20% p-type InGaN external base layer 17 is small, the effect of regrowth cannot be expected, and if the thickness is large, it may hinder device fabrication. Therefore, it is desirable that the thickness be 1 nm or more and 100 nm or less. Here, as shown in FIG.
- defects caused by etching generate positive charges 16 on the p-type InGaN base layer 2.
- This positive charge 16 is the cause of the poor ohmic characteristics.
- this In composition is 20%, and the p-type InG GaN external base layer 17 is not completely distorted. of! ) It is expected that a certain amount of negative polarization charge 15 will be generated between the type InGaN base layer 2.

- the size of the electrodes is 50mX80m, and the spacing is 20m.
- the regrowth base layer 8 was not regrown. Therefore, all current flows through the interface between the 7% p-type InGaN base layer 2 and the 20% regrown p-type InGaN external base layer 17. Will pass.

Since the conduction band discontinuity of the n-type GaN emitter layer 1 and the p-type In GaN base layer 2 with 7% In composition is 0.2 V, the rise is almost equal to this discontinuity. Voltage was obtained. The deviation of the rise voltage from the expected value is less than 0.1 V.
- the current gain of the HBT of the present embodiment is more than 100 times larger than that of the conventional method, and the deviation of the rising voltage from the expected value is also small. It decreased sharply to 150 or less.
- the p-type InGaN external base layer 8 was used for the regrowth layer. As a result, the characteristics of the HBT can be greatly improved. It is considered that the processing damage was repaired by the I ⁇ atoms contained in the ⁇ -type nitride semiconductor. Industrial applicability
