Avalanche photodiode for use in harsh environments
专利汇可以提供Avalanche photodiode for use in harsh environments专利检索，专利查询，专利分析的服务。并且An aspect of the present invention is directed to an avalanche photodiode (APD) device for use in oil well drilling applications in harsh, down-hole environments where shock levels are near 250 gravitational acceleration (G) and/or temperatures approach or exceed 150° C. Another aspect of the present invention is directed to an APD device fabricated using SiC materials. Another aspect of the present invention is directed to an APD device fabricated using GaN materials. According to an embodiment of the present invention, an avalanche photodiode for detecting ultraviolet photons comprises a substrate (110) having a dopant of a first type; a first layer (111) having a dopant of a first type, positioned on top of the substrate; a second layer (112) having a dopant of a second type, positioned on top of the first layer; a third layer (114) having a dopant of a second type, positioned on top of the second layer; a passivation layer (116,122) for providing electrical passivation on a surface of the avalanche photodiode; a phosphorous silicate glass layer (124) for limiting mobile ion transport, positioned on top of the third layer; and a pair of metal electrodes (118,120) for providing an ohmic contact wherein a first electrode is positioned below the substrate and a second electrode is positioned above the third layer; wherein the avalanche photodiode comprises a first sidewall and a second sidewall forming a sloped mesa shape; and wherein the avalanche photodiode operates in an environment comprising a temperature approximately equal to 150 degrees Celsius.，下面是Avalanche photodiode for use in harsh environments专利的具体信息内容。
