Patent number: 9659866Abstract: Dielectric pedestal structures embedded in a sacrificial material layer is formed between a substrate and an alternating stack of insulating layers and spacer material layers. After memory openings are formed through the alternating layer, a cavity is formed by removal of the sacrificial material layer selective to the dielectric pedestal structures. A memory film, a semiconductor channel layer, and a dielectric core are sequentially formed in the volume including the cavity and the memory openings. A backside trench is formed through the alternating stack in an area that straddles the dielectric pedestal structures. By recessing the dielectric pedestal structures selective to the semiconductor channel layer, planar regions and vertical regions of the semiconductor channel layer can be physically exposed, which are converted into source regions. Contact resistance can be lowered due the increased contact area provided by vertical source portions.Type: GrantFiled: July 8, 2016Date of Patent: May 23, 2017Assignee: SANDISK TECHNOLOGIES LLCInventor: Toru Ishigaki

Patent number: 8095050Abstract: A developer level control blade is provided which can form a developer layer on a developer carrying member in a proper thickness and in a uniform state and can keep the developer, in particular, color toner particles from melt-adhering to the charge control face so that faulty images such as lines and non-uniformity can be kept from occurring. Also provided is a process for manufacturing this developer level control blade. The process for manufacturing the developer level control blade is characterized by having the steps of extruding a blade member material melted to liquefy, covering therewith a support member thin-plate metal member at an edge portion thereof to join the both together, and cooling the blade member material to solidify, followed by cutting in a preset length.Type: GrantFiled: March 19, 2008Date of Patent: January 10, 2012Assignee: Canon Kasei Kabushiki KaishaInventors: Kazuaki Iwata, Naohiko Nakano, Toru Ishigaki

Patent number: 7995394Abstract: Program disturb is reduced in a non-volatile storage system during a program operation for a selected word line by initially using a pass voltage with a lower amplitude on word lines which are adjacent to the selected word line. This helps reduce charge trapping at floating gate edges, which can widen threshold voltage distributions with increasing program-erase cycles. When program pulses of higher amplitude are applied to the selected word line, the pass voltage switches to a higher level to provide a sufficient amount of channel boosting. The switch to a higher pass voltage can be triggered by a specified program pulse being applied or by tracking lower state storage elements until they reach a target verify level. The amplitude of the program voltage steps down when the pass voltage steps up, to cancel out capacitive coupling to the selected storage elements from the change in the pass voltage.Type: GrantFiled: July 30, 2009Date of Patent: August 9, 2011Assignee: SanDisk Technologies Inc.Inventors: Yingda Dong, Toru Ishigaki, Ken Oowada

Patent number: 7876611Abstract: Capacitive coupling from storage elements on adjacent bit lines is compensated by adjusting voltages applied to the adjacent bit lines. An initial rough read is performed to ascertain the data states of the bit line-adjacent storage elements, and during a subsequent fine read, bit line voltages are set based on the ascertained states and the current control gate read voltage which is applied to a selected word line. When the current control gate read voltage corresponds to a lower data state than the ascertained state of an adjacent storage element, a compensating bit line voltage is used. Compensation of coupling from a storage element on an adjacent word line can also be provided by applying different read pass voltages to the adjacent word line, and obtaining read data using a particular read pass voltage which is identified based on a data state of the word line-adjacent storage element.Type: GrantFiled: August 8, 2008Date of Patent: January 25, 2011Assignee: SanDisk CorporationInventors: Deepanshu Dutta, Jeffrey W.

Patent number: 7305405Abstract: An information storage unit stores pieces of information that are classified on the basis of their relationships. An information providing unit provides a client terminal with information stored in the information storage unit via a communication network in response to an access request from the client terminal. An access frequency acquiring unit acquires access frequencies, for respective classification items of the pieces of information, of accesses to the pieces of information. An information generating unit generates prescribed information so that pieces of information of plural classification items will be displayed in the client terminal in such a form as to be based on histories of the access frequencies.Type: GrantFiled: April 29, 2004Date of Patent: December 4, 2007Assignee: Fuji Xerox Co.
