Talk:Yoshiaki Hagiwara

Can you explain the recent publication by Yoshiaki Daimon Hagiwara in IEEE EDS NEWSLETTER 2023 Jan Issue ?
SONY and Hagiwara claimes that Hagiwara invented Pinned Photodiode. But Fossum claimed in his 2014 paper that Teranishi invented in 1980. Who is telling the truth on the invention of Pinned Photodiode ??? 111.108.209.27 (talk) 18:52, 27 February 2023 (UTC)
