摘要： A memory cell and a non-volatile semiconductor memory device are disclosed. Nitride sidewall layers (32a and 32b) are respectively disposed in a first sidewall spacer (28a) and a second sidewall spacer (28b), to separate a memory gate electrode (MG) and a first select gate electrode (DG) from each other and the memory gate electrode (MG) and a second select gate electrode (SG) from each other. Hence, a breakdown voltage is improved around the memory gate electrode (MG) as compared with a conventional case in which the first sidewall spacer (28a) and the second sidewall spacer (28b) are simply made of insulating oxide films. The nitride sidewall layers (32a and 32b) are disposed farther from a memory well (MW) than a charge storage layer (EC). Hence, charge is unlikely to be injected into the nitride sidewall layers (32a and 32b) at charge injection from the memory well (MW) into the charge storage layer (EC), thereby preventing an operation failure due to charge storage in a region other than the charge storage layer (EC).

摘要： When a memory cell (MC) is downsized by reducing the distance between a drain region (12a) and a source region (12b) on the surface of a fin (S2) with a high impurity concentration inside the fin (S2), the shape of the fin (S2) can be set such that a potential difference between a memory gate electrode (MG) and the fin (S2) is reduced to suppress the occurrence of disturbance. Accordingly, the memory cell (MC) achieves downsizing and suppression of the occurrence of disturbance.

摘要： A non-volatile SRAM memory cell and a non-volatile semiconductor memory device capable of programming SRAM data in a SRAM (15) to a non-volatile memory unit (16) through fast operation of the SRAM (15) are disclosed. A non-volatile semiconductor memory device (1) can achieve reduction in a voltage necessary for a programming operation to program SRAM data to the non-volatile memory unit (16).

摘要： A voltage applied to a bit line (BL1) or a voltage applied to a source line (SL) is reduced to a value that allows a first select gate structure (5) or a second select gate structure (6) to block electrical connection between the bit line (BL1) and a channel layer (CH) or between the source line (SL) and the channel layer (CH), irrespective of a charge storage gate voltage needed to inject charge into a charge storage layer (EC) by a quantum tunneling effect. In accordance with the reduction in voltage(s) applied to the bit line (BL1) and the source line (SL), thickness of a first select gate insulating film (30) of the first select gate structure (5) and thickness of a second select gate insulating film (33) of the second select gate structure (6) are reduced. High-speed operation is achieved correspondingly. In accordance with the reduction in voltage(s) applied to the bit line (BL1) and the source line (SL), thickness of a gate insulating film of a field effect transistor in a peripheral circuit that controls a memory cell is reduced. The area of the peripheral circuit is reduced correspondingly.

摘要： A method for producing a semiconductor integrated circuit device, and a semiconductor integrated circuit device are disclosed. In the method, a first select gate electrode (G2a, G2b) and a second select gate electrode (G3a, G3b) electrically insulated from each other are formed in a memory circuit region (ER1) through a photomask process of forming a logic gate electrode (G5, G6) in a peripheral circuit region (ER2). Thus, even when the first select gate electrode (G2a or G2b) and the second select gate electrode (G3a, G3b) are formed to be separately controllable, an extra dedicated photomask process of fabricating only the memory circuit region (ER1) does not need to be performed in addition to a conventional dedicated photomask process of fabricating only a memory circuit region. Thereby, production cost is reduced accordingly.

摘要： Provided is a non-volatile semiconductor storage device that can surely prevent malfunction of read transistors without an increase in the number of bit lines. In a non-volatile semiconductor storage device (1), a second bit line (BLN1) that is connected to a program transistor (5a) of a first cell (2a) so as to serve for data writing is caused to double as a bit line for reading in another second cell (2b) by switching switch transistors (SWa, SWb), and program transistors (5a, 5b) and erase transistors (3a, 3b) that serve as charge transfer paths at the time of writing data and at the time of deletion of data are provided. This configuration makes it possible to surely prevent malfunction of read transistors (4a, 4b) that occurs when the read transistors are used for writing or deletion of data, without increasing the number of bit lines.

摘要： A semiconductor integrated circuit device, and a method for manufacturing a semiconductor integrated circuit device are disclosed. A first select gate electrode (DG) and a second select gate electrode (SG) are sidewall-shaped along sidewalls of a memory gate structure (4). With this configuration, the memory gate structure (4) is not disposed on the first select gate electrode (DG) and the second select gate electrode (SG). Accordingly, the memory gate structure (4), the first select gate structure (5), and the second select gate structure (6) can have equal heights, thereby achieving reduction in size as compared to a conventional case. In addition, a silicide layer (S1) on the first select gate electrode (DG) and a silicide layer (S2) on the second select gate electrode (SG) can be separated farther from a memory gate electrode (MG) by the thickness of a cap film (CP1). Accordingly, the silicide layers (S1 and S2) on the first select gate electrode (DG) and the second select gate electrode (SG) are unlikely to contact with the memory gate electrode (MG), thereby preventing a short-circuit defect of the memory gate electrode (MG).

摘要： In a semiconductor memory device (1), voltage application from a memory gate electrode (G) of the memory capacitor (4) to a word line can be blocked by a rectifier element (3) depending on values of voltages applied to the memory gate electrode (G) and the word line without using a conventional control circuit. The configuration eliminates the need to provide a switch transistor and a switch control circuit for turning on and off the switch transistor as in conventional cases, and accordingly achieves downsizing. In the semiconductor memory device (1), for example, each bit line contact (BC15) is shared by four anti-fuse memories (2a 6 , 2a 7 , 2a 10 , and 2a 11 ) adjacent to each other and each word line contact (WC12) is shared by four anti-fuse memories (2a 3 , 2a 4 , 2a 7 , and 2a 8 ) adjacent to each other, thereby achieving downsizing of the entire device as compared to a case in which the bit line contact and the word line contact are individually provided to each anti-fuse memory.
