Status of p-on-n Arsenic-Implanted HgCdTe Technologies

Abstract: In this paper recent developments made by the French Atomic Energies and Alternative Energies Commission (CEA) at the Electronics and Information Technology Laboratory (LETI) on the fabrication of planar p-on-n HgCdTe photodiodes are reported. Results obtained on long-wavelength infrared (LWIR) liquid-phase epitaxy (LPE) and mid-and short-wavelength infrared (MWIR/SWIR) molecular beam epitaxy (MBE) have been previously published. For these photodiodes, p-type doping is obtained by arsenic implantation followed… Show more

“…Measurements of majority carriers mobility are up to 110×10 3 cm 2 /V/s for LWIR detectors, confirming the high quality of In-doped MCT [4]. pon-n photodiodes are manufactured by ion-implantation of Arsenic [11]. Two steps of annealing after implantation are necessary: one to repair defects resulting from ion bombardment and activate As and the other one, under Hg overpressure vapor, to restore n-type doping of the base layer.…”

“…The p-on-n photodiodes are manufactured by ion-implantation of arsenic. 11 Two steps of annealing after implantation are necessary: one to repair defects resulting from ion bombardment and activate As and the other, under overpressure of Hg vapor, to restore n-type doping of the base layer. Hall and maximum entropy mobility spectrum analysis (MEMSA) 12 measurements show that As activation is greater than 50%.…”

“…В частности, не всегда может быть реализована диодная p−n-структура, обеспечивающая эффективную инжекцию электронов и дырок в активную область. Например, существуют технологические трудности при создании полупроводниковых слоев с p-типом проводимости в материалах HgCdTe или AlGaN [6][7][8][9]. Как альтернатива прямой токовой накачке может использоваться оптическая накачка или накачка электронным лучом, что не всегда эффективно или же может значительно усложнять систему.…”
