Publication number: 20140302630Abstract: The present invention discloses a method for inhibiting the electric crosstalk of back illuminated CMOS image sensor. This invention comprises, two ion implanting layers are implanted at the different area of the backside of the pixel unit after the thickness of the backside of CMOS image sensor is reduced. The ion concentrations implanted into the two layers are controlled to decrease progressively from top to bottom. An electric field is formed from top to bottom inside the epitaxial layer. The said electric field absorbs the incident light which arrives at the substrate region outside of the space charge of the photodiode. It reduces the electron diffuses in different pixels. Consequently, it reduces the electric crosstalk of pixels, improves the manufacture process and improve the image quality of the of CMOS image sensor.Type: ApplicationFiled: December 5, 2013Publication date: October 9, 2014Applicant: SHANGHAI HUALI MICROELECTRONICS CORPORATIONInventors: Zhi TIAN, QiuMin JIN

Patent number: 8853670Abstract: In a semiconductor device 100, it is possible to prevent C from piling up at a boundary face between an epitaxial layer 22 and a group III nitride semiconductor substrate 10 by the presence of 30×1010 pieces/cm2 to 2000×1010 pieces/cm2 of sulfide in terms of S and 2 at % to 20 at % of oxide in terms of O in a surface layer 12 with a front surface 10a having a specific plane orientation. Accordingly, a high-resistivity layer is prevented from being formed at the boundary face between the epitaxial layer 22 and the group III nitride semiconductor substrate 10. Consequently, it is possible to improve the emission intensity of the semiconductor device 100.Type: GrantFiled: October 26, 2011Date of Patent: October 7, 2014Assignee: Sumitomo Electric Industries, Ltd.Inventor: Keiji Ishibashi

Patent number: 8815666Abstract: Provided is a power device. The power device may include a two-dimensional electron gas (2-DEG) layer in a portion corresponding to a gate electrode pattern since a second nitride layer is further formed on a lower portion of the gate electrode pattern after a first nitride layer is formed and thus, may be capable of performing a normally-OFF operation. Accordingly, the power device may adjust generation of the 2-DEG layer based on a voltage of a gate, and may reduce power consumption. The power device may regrow only the portion corresponding to the gate electrode pattern or may etch a portion excluding the portion corresponding to the gate electrode pattern and thus, a recess process may be omissible, a reproducibility of the power device may be secured, and a manufacturing process may be simplified.Type: GrantFiled: September 25, 2013Date of Patent: August 26, 2014Assignee: Samsung Electronics Co., Ltd.Inventor: Jae Hoon Lee
