Publication number: 20240159789Abstract: The present invention enables automatic detection of failure in a plunger in a syringe pump unit by an automated analysis device, which includes a sample dispensing mechanism; a reagent dispensing mechanism; and a control unit for controlling operation of the sample dispensing mechanism and the reagent dispensing mechanism and analyzing the sample. The sample dispensing mechanism and the reagent dispensing mechanism each have a plunger for suctioning in and expelling liquid, and a plunger drive unit for driving the plunger. The control unit controls operation with the plunger drive unit of the reagent dispensing mechanism so that the plunger moves reciprocally by a backlash distance a predetermined number of times. Failure of the plunger is detected by detecting, using the liquid level sensing function, the amount of liquid discharged into the liquid storage container.Type: ApplicationFiled: December 3, 2021Publication date: May 16, 2024Applicant: HITACHI HIGH-TECH CORPORATIONInventors: Yuichi Iwase, Takushi Miyakawa, Shunsuke Miyamoto, Masafumi Miyake

Publication number: 20230230853Abstract: A manufacturing apparatus of a semiconductor device includes a stage, a mounting tool, a pressing mechanism, and a controller. The pressing mechanism moves the mounting tool in a vertical direction and applies a load to a chip. The controller is configured to perform a first process and a detection process. In the first process, after bringing the chip into contact and until a bump melts, the chip is heated by the mounting tool and a command position of the pressing mechanism is constantly updated so that a positional deviation is constant. In the detection process, melting of the bump is detected based on a decrease in the pressing load.Type: ApplicationFiled: June 14, 2021Publication date: July 20, 2023Applicant: SHINKAWA LTD.Inventors: Daisuke TANI, Takahiro SHIMIZU, Masafumi MIYAMOTO

Patent number: 9935124Abstract: Split memory cells can be provided within an alternating stack of insulating layers and word lines. At least one lower-select-gate-level electrically conductive layers and/or at least one upper-select-level electrically conductive layers without a split memory cell configuration can be provided by limiting the levels of separator insulator structures within the levels of the word lines. At least one etch stop layer can be formed above at least one lower-select-gate-level spacer material layer. An alternating stack of insulating layers and spacer material layers is formed over the at least one etch stop layer. Separator insulator structures are formed through the alternating stack employing the etch stop layer as a stopping structure. Upper-select-level spacer material layers can be subsequently formed. The spacer material layers and the select level material layers are formed as, or replaced with, electrically conductive layers.Type: GrantFiled: July 26, 2016Date of Patent: April 3, 2018Assignee: SANDISK TECHNOLOGIES LLCInventors: Masatoshi Nishikawa, Masafumi Miyamoto, Hiroyuki Ogawa

Patent number: 9935123Abstract: An alternating stack of sacrificial material layers and insulating layers is formed over a substrate. Replacement of sacrificial material layers with electrically conductive layers can be performed employing a subset of openings. A predominant subset of the openings is employed to form memory stack structures therein. A minor subset of the openings is employed as access openings for introducing an etchant to remove the sacrificial material layers to form lateral recesses and to provide a reactant for depositing electrically conductive layers in the lateral recesses. By distributing the access openings across the entirety of the openings and eliminating the need to employ backside trenches for replacement of the sacrificial material layers, the size and lateral extent of backside trenches can be reduced to a level sufficient to accommodate only backside contact via structures.Type: GrantFiled: July 26, 2016Date of Patent: April 3, 2018Assignee: SANDISK TECHNOLOGIES LLCInventors: Masatoshi Nishikawa, Masafumi Miyamoto, James Kai

Patent number: 9837431Abstract: A vertical memory device including dual memory cells per level in each memory opening can have dielectric separator dielectric structures that protrude into a facing pair of sidewalls of the memory stack structure within the memory opening. A pair of inactive sections of a vertical semiconductor channel facing the dielectric separator dielectric structures is laterally recessed from control gate electrodes. Control of the threshold voltage of such a vertical memory device can be enhanced because of the dielectric separator dielectric structures. The fringe field from the control gate electrodes is weaker due to an increased distance between the control gate electrodes and the inactive sections of the vertical semiconductor channel. The memory stack structure can have concave sidewalls that contact the dielectric separator dielectric structures and convex sidewalls that protrude toward the control gate electrodes.Type: GrantFiled: January 28, 2016Date of Patent: December 5, 2017Assignee: SANDISK TECHNOLOGIES LLCInventors: Masatoshi Nishikawa, Hiroaki Iuchi, Masafumi Miyamoto
