    • A photoconductive isotype heterojunction impedance-matched infrared detector has blocking contacts (66 and 68) which are positioned on the bottom side of the detector. Blocking contacts (66 and 68) prevent transfer of minority carriers from active region (42a) of the detector, thereby extending the lifetime of these carriers. The detector is formed by first fabricating active layer (42) followed by isotype blocking layer (44) on growth substrate (40). These layers are etched and appropriate passivation layers (93) and contacts (98 and 100) are applied. Mechanical supporting substrate (90) is applied to the detector and growth substrate (40) is removed. Etch stop holes (48 and 50) are formed which extend into active layer (42) of the detector. A precision thickness of active layer (42), required in an impedance-matched detector design, is produced by thinning active layer (42) in an etching process until the surface of active layer (42) reaches etch stop hole (48 and 50).
    • 光导同种异质结阻抗匹配红外检测器具有位于检测器底部的阻挡触点(66和68)。 阻塞触点(66和68)防止少数载流子从检测器的有源区(42a)传递,从而延长这些载体的寿命。 检测器通过首先在生长衬底(40)上制造活性层(42),随后同型阻断层(44)形成。 蚀刻这些层并施加适当的钝化层(93)和触点(98和100)。 将机械支撑衬底(90)施加到检测器,并移除生长衬底(40)。 形成延伸到检测器的有源层(42)的蚀刻停止孔(48和50)。 在阻抗匹配检测器设计中所需的有源层(42)的精密厚度是通过在蚀刻工艺中减薄有源层(42)直到活性层(42)的表面到达蚀刻停止孔(48和50) 。
