Patent number: 9865635Abstract: An image sensor and a method of fabricating the same are disclosed. The image sensor may include a substrate including an active region defined by a device isolation layer, a photoelectric conversion layer, a well impurity layer, a floating diffusion region, and a transfer gate. When viewed in a plan view, a lower portion of the transfer gate may include a first surface in contact with the device isolation layer, a second surface substantially perpendicular to the first surface, and a third surface connected to the first and second surfaces. The third surface may face the floating diffusion region. A first portion of a gate insulating layer may be adjacent to the third surface and thinner than a portion adjacent to the first surface or the second surface, and this may facilitate more efficient transfer of an electron from the photoelectric conversion layer to the floating diffusion region.Type: GrantFiled: January 17, 2017Date of Patent: January 9, 2018Assignee: SAMSUNG ELECTRONICS CO., LTD.Inventors: Donghyuk Park, Seungwon Cha, Cheolju Kang, Yitae Kim, Jongeun Park, Jungchak Ahn, Yujung Choi

Patent number: 9001442Abstract: Technologies are described herein for detecting adjacent track interference in a storage device using a size-adjustable sliding window. A value for an inter-track interference factor associated with at least one adjacent track is determined for a first area of a data track of the storage device. The first area may encompass a plurality of sectors of the data track. Next, it is determined whether the value of the calculated inter-track interference factor is greater than a threshold value, and if so, an indication of inter-track interference corresponding to the first area is stored in the storage device.Type: GrantFiled: March 15, 2013Date of Patent: April 7, 2015Assignee: Seagate Technology LLCInventors: Donghyuk Park, Seungyoul Jeong, Joowon Cho

Patent number: 8976473Abstract: Technologies are described herein for cancelling adjacent track interference in a storage device using an ITI predictor determined from predetermined data patterns in adjacent tracks. A first signal is read from a first portion of a data track, the first portion containing a first predetermined data pattern. Next, a value for an inter-track interference predictor associated with an adjacent track is determined based on the first signal, the first predetermined data pattern, and a second predetermined data pattern contained in a corresponding portion of the adjacent track. A second signal is read from a second portion of the data track, and inter-track interference from the adjacent track in the second signal is cancelled utilizing the value for the inter-track interference predictor.Type: GrantFiled: May 21, 2014Date of Patent: March 10, 2015Assignee: Seagate Technology LLCInventors: Donghyuk Park, Mansik Shim, Jiyoung Lee, Taehoon Lee
