The CDTI transfer register offers a charge transfer inefficiency lower than 10\u22124 and a low dark current o 0.11nA\/cm2 at room temperature. In this work, the timing diagram is adapted to use this CDTI transfer register in an electron multiplication mode. The results highlight some limitations of this device in such an EM configuration: for instance, an unexpected increase in the dark current is observed. A design modification is then proposed to overcome these limitations and rely on the addition of an electrode on the top of the register. Thus, this new device preserves the good transfer performance of the register while adding an electron multiplication function. Technology computer-aided design (TCAD) simulations in 2D and 3D are performed with this new design and reveal a very promising structure.<\/jats:p>","DOI":"10.3390\/s23239518","type":"journal-article","created":{"date-parts":[[2023,11,30]],"date-time":"2023-11-30T09:37:54Z","timestamp":1701337074000},"page":"9518","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Development of a Charge-Multiplication CMOS Image Sensor Based on Capacitive Trench for Low-Light-Level Imaging"],"prefix":"10.3390","volume":"23","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1829-3465","authenticated-orcid":false,"given":"Olivier","family":"Marcelot","sequence":"first","affiliation":[{"name":"ISAE-SUPAERO, Universit\u00e9 de Toulouse, F-31055 Toulouse, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2230-5027","authenticated-orcid":false,"given":"Marjorie","family":"Morvan","sequence":"additional","affiliation":[{"name":"ISAE-SUPAERO, Universit\u00e9 de Toulouse, F-31055 Toulouse, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Antoine","family":"Salih Alj","sequence":"additional","affiliation":[{"name":"ISAE-SUPAERO, Universit\u00e9 de Toulouse, F-31055 Toulouse, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stephane","family":"Demiguel","sequence":"additional","affiliation":[{"name":"Thales Alenia Space, 5 All.
