Patent number: 7465915Abstract: A method for measuring incident light employing a simple semiconductor structure provided with a single electron-capturing section corresponding to incident light, and a sensor having a spectroscopic mechanism employing the same are provided. A spectroscopic sensor includes a semiconductor substrate (1), a first diffusion layer (2) provided on the semiconductor substrate (1), a second diffusion layer (3)provided at a part of the first diffusion layer (2), and an electrode (7)film provided on the first diffusion layer (2) with an insulating film (4) provided therebetween, the electrode film (7) transmitting the incident light and being applied with a gate voltage. In the spectroscopic sensor, the gate voltage is varied, the depth (position) for capturing electrons generated in the first diffusion layer (2) by the incident light is varied so as to correspond to the gate voltage, and a current indicating the quantity of the electrons is measured.Type: GrantFiled: March 25, 2004Date of Patent: December 16, 2008Assignee: Japan Science and Technology AgencyInventors: Kazuaki Sawada, Makoto Ishida, Yuki Maruyama, Hideki Muto

Patent number: 7345268Abstract: A back-illuminated image sensor has a converting layer 21, charge collecting portions 24, and suppressing regions 23 and 29. The converting layer 21 for converting an incident beam into signal charges is formed on one side of an incident face 8 on which an incident beam is irradiated. The converting layer 21 is provided for each of pixels arranged in two dimensions. The charge collecting portions 24 for collecting signal charges generated in the converting layer 21 extends from the converting layer 21 to a surface 22 opposite to the incident face 8. The suppressing regions 23 and 29 for suppressing the flow of the signal charges from the converting layer 21 to peripheral circuits 26 is formed between the converting layer 21 and the peripheral circuits 26.Type: GrantFiled: December 26, 2003Date of Patent: March 18, 2008Assignees: Shimadzu CorporationInventors: Takeharu Etoh, Hideki Muto
