Definitions
- the present invention relates to a semiconductor device and a manufacturing technique thereof, and more particularly to a manufacturing technique of a nonvolatile semiconductor memory device in which the redundancy efficiency of an NOR flash memory is improved.
- Flash memory which is a non-volatile semiconductor memory device, has features of RAM (Random Access Memory) that can rewrite data, and RM (Read Only Memory) that can retain data even after the power is turned off.
- RAM Random Access Memory
- RM Read Only Memory
- This is a non-volatile semiconductor memory device that has the features described above.
- the smallest unit of storage in a memory device is called a cell, and one cell stores one bit.
- SRAM and DRAM a single cell is composed of multiple elements, whereas a single cell in flash memory is composed of only one transistor, which is the minimum number of elements.
- a plurality of single cells of such a flash memory are doubled to form one sector (block), and a storage area is configured as a set of these sectors. Data erasure in this storage area is performed in units of sectors (or in one chip).
- Flash memories are roughly classified into NAND type and N0R type.
- NAND flash memory uses 8-bit or 16-bit memory cells connected in series to a single data line, and uses the Fowler-Nordheim tunnel phenomenon that uses the entire surface of the silicon substrate and floating gate for writing and erasing.
- NOR-type flash memory has individual memory cells connected in parallel to a single data line, and uses hot electrons for writing and Fowler-Noredheim tunneling for erasing.
- FIG. 1 is a schematic cross-sectional view for explaining a connection state between an NR flash memory cell and a bit line.
- One NOR type flash memory cell 10 includes a semiconductor substrate 11, a floating gate 12 and a word line 13 formed in an insulating layer 17 provided thereon, and a contact portion 14 formed in the insulating layer 1 1. (Consisting of a contact hole and a conductive member therein) and a semiconductor substrate 11 (specifically, an impurity formed on the insulating layer 17 via the contact portion 14. A bit line 15 in contact with the diffusion layer.
- Each cell 10 of the NOR type flash memory can identify the presence or absence of information by storing electrons injected by applying a voltage from the word line 13 in the floating gate 12.
- the word line 13 and the contact portion 14 may be electrically short-circuited due to the presence of any defect 16 to cause malfunction.
- the word line 13 still shorts the contact portion 14 connected to the redundant bit line 15. Therefore, a sufficient voltage cannot be supplied to the word line 13 at the time of data writing, reading, and erasing, and the malfunction is not solved.
- FIG. 2 is a diagram for explaining a circuit configuration of the NOR type flash memory. As shown in this figure, one memory cell 10 is connected between the word line 13 and the bit line 15, and when any one of the memory cells 10 connected to the bit line becomes conductive, the bit line 15 The electric potential of will be the lower force S.
- the threshold voltage of a cell that is only erased but not programmed gradually becomes a negative value, and a current flows even when the gate voltage is 0V.
- N ⁇ R flash memory cell Is detected as the current flowing in the bit line, but the current in the cells connected to the non-redundant bit lines (15 _0, 15-2, 15-3) is the redundant word line 13— It is affected by the current of the cell connected to 1. For this reason, it is difficult to accurately read the current of the selected cell.
- the malfunction caused by the electrical short circuit between the word line 13 and the contact portion 14 induced by the defect cannot be redundant and cannot be remedied.
- the present invention has been made in view of a serious problem, and an object of the present invention is to eliminate a malfunction caused by a defect located between a word line and a contact hole only by bit line redundancy. It is an object of the present invention to provide a method for manufacturing a nonvolatile semiconductor memory device that can be remedied by the above-described method, and to contribute to an improvement in manufacturing yield.
- the exposure system of the present invention includes an inspection device that detects a defect on the surface of a semiconductor substrate, and a control unit that stores physical coordinates of the defect on the semiconductor substrate. And an exposure apparatus in which exposure conditions are controlled by the control unit, and a region corresponding to the physical coordinates of the defect is dummy-exposed to form no contact hole in the region.
- the dummy exposure is defocus condition exposure or color exposure.
- the exposure apparatus is a scanner type electron beam exposure apparatus.
- the present invention also includes a step of detecting defects on the surface of the semiconductor substrate prior to contact hole formation, and a step of storing physical coordinates of the defects detected in the first step on the semiconductor substrate. Then, exposure is performed to form a contact hole in a predetermined region on the surface of the semiconductor substrate, while a region corresponding to the physical coordinates stored in the storing step is dummy exposed to form a contact hole in the region. And a step of manufacturing a semiconductor device.
- the dummy exposure in the exposing step is defocus condition exposure or color exposure.
- the exposing step forms a contact hole according to the NOR type memory cell arrangement. Further, it is preferable that the method further includes a step of replacing a bit line including the region related to the defect with a redundant bit line.
- the present invention provides a semiconductor substrate, an insulating layer formed on the semiconductor substrate, and the insulation A bit line formed on the layer; a contact portion formed in the insulating layer to form a contact between the bit line and the semiconductor substrate; a floating gate and a word line formed in the insulating layer; The contact portion is regularly arranged, and the semiconductor device includes a portion in which the contact is not formed in the regular arrangement. In this semiconductor device, the bit line including the region related to the defect is replaced with a redundant bit line.
- a contact hole is not formed in a region where a defect exists, a word line (control gate) and a bit line are short-circuited through the contact hole, although it becomes a defective cell. There is nothing that can be done, but it is possible to relieve by simply applying the bit line redundancy used in the past.

- FIG. 2 is a diagram for explaining a circuit configuration of a NOR type flash memory.
- FIG. 3 is a block diagram for explaining a state of linking a defect inspection apparatus that performs defect inspection before forming a contact hole and a scanner type exposure apparatus that performs exposure for forming a contact hole. .
- FIG. 4 is a flowchart for illustrating and explaining a part of a series of processes from a defect inspection process to an exposure process.
- FIG. 5A is a first diagram for explaining the components of the transistor formed by the process of the flowchart shown in FIG. 4, and FIG. 5B is formed by the process of the flowchart shown in FIG.
- FIG. 5C is a third diagram for explaining the state of the components of the transistor formed by the process of the flowchart shown in FIG.
- FIG. 5D is a fourth diagram for explaining the state of the components of the transistor formed by the process of the flowchart shown in FIG.
- FIG. 6A is a top plan view for explaining a conventional method for avoiding a short circuit between a word line and a contact hole by not forming a contact hole
- FIG. 6B is a contact hole.
- FIG. 6 is an upper plan view for explaining the method of the present invention for avoiding a short circuit between the word line and the contact hole by not forming the gate.
- the root cause of the above-described malfunction is that defects (for example, particles adhering to the wafer (semiconductor substrate)) generated in the manufacturing process of the nonvolatile semiconductor memory device are normal in the subsequent processes. This is an obstacle to the formation of a proper contact hole. In addition, an electrical short circuit between the contact hole and the word line creates a situation in which redundancy is impossible. However, since such a defect can be detected by inspecting the defect prior to the contact hole formation process, if the contact hole is not formed at the location where the defect exists, it is possible to connect the word line via the contact hole. There is no short circuit of the bit line, and it can be remedied by simply applying the bit line redundancy used conventionally. In other words, by converting “defects such as particles” into the form of “defects that do not have contact holes”, it is possible to apply the conventional redundancy method and relieve malfunctions.
- defects for example, particles adhering to the wafer (semiconductor substrate)
- the defect inspection process before the contact hole formation and the exposure process for forming the contact hole are linked. Specifically, the position (physical coordinates) on the wafer of the defect detected in the defect detection process before forming the contact hole is stored, and exposure (dummy exposure) is performed under the condition that no contact hole is formed at the location. ).
- dummy exposure refers to, for example, exposure under defocusing conditions so that contact holes are not formed, and “color exposure” (no exposure beam exposure) in which no exposure is performed at that location.
- this dummy exposure will be described as exposure under a defocus condition, but the present invention is not limited to such a dummy exposure mode, and is detected in a defect detection process before contact hole formation. As described above, it is sufficient that the contact hole is not formed at the position (physical coordinate) of the defect on the wafer.
- the position of such a defect is specified by pattern recognition that compares images of adjacent circuit patterns, and in that case, not only physical coordinates but also the spatial extent (size) of the defect can be measured. it can.
- the exposure apparatus used in the present invention is of a “scanner type” (for example, EB exposure apparatus) that can set exposure conditions for each contact hole. If there is a defect in the contact hole formation region, dummy exposure is performed so that the exposure condition is consciously defocused and no actual exposure is performed.
- FIG. 3 is a block diagram of an exposure system for explaining a state of linking a defect detection apparatus that performs defect inspection before contact hole formation and a scanner type exposure apparatus that performs exposure for contact hole formation.
- 310 is a surface inspection device
- 320 is a scanner type exposure device
- both are provided with stages (311, 321) on which a wafer 301 is placed.
- physical coordinate information of defects (for example, particles) 302 on the wafer 301 detected by the defect inspection before contact hole formation by the surface inspection device 310 is transmitted to the controller (for example, a personal 'computer) 330 and stored. .
- the above-described surface inspection is performed by a general method.
- laser light is obliquely incident on the surface of the wafer 301, and the scattered light is monitored by the detection unit 312. This is done by analyzing the turn.
- the detection unit 312. This is done by analyzing the turn.
- the wafer that has undergone such surface inspection is subjected to exposure for forming a contact hole.
- a contact hole is formed at the coordinate position on the wafer 301 where the defect 302 exists. If this happens, it will not be possible to relieve defects only by bit line redundancy. Therefore, the controller 330 transmits a signal for defocusing the exposure condition to the exposure unit 322 when the exposure apparatus 320 performs exposure of the area on the wafer 302 corresponding to the defect 302.
- a signal for not performing exposure on the area on wafer 302 corresponding to defect 302 is transmitted to exposure unit 322. Is done.
- FIG. 4 is a flowchart for illustrating and explaining a part of a series of processes from the defect inspection step to the exposure step.
- 5A to 5D are diagrams for explaining the state of the components of the transistor formed by the flow chart process shown in FIG.
- step S201 After the second gate etching process (step S201) is completed, the presence or absence of defects on the wafer is confirmed by a defect inspection device (step S202). If a defect is detected here, Physical coordinate information corresponding to the position of each individual defect is transmitted to the controller and stored (step S203). Further, deposition for forming a sidewall is executed (step S204), and after this process, defect inspection is executed in the same manner as described above (step S205), and the result is stored in the controller (step S206).
- the floating gate 12 and the control gate 13a are provided on the surface of the substrate 11 on which the source 11a and the drain l ib are formed, and side walls are provided on the side surfaces of these gates. Assume that 17 is formed. Originally, a contact hole is formed between the sidewalls 17 of the drain rib region. However, if there is a defect 16 in this area, it is necessary to avoid forming contact holes in this area. Therefore, the physical coordinate information of the defect 16 detected in step S205 is transmitted to and stored in the controller (step S206) and used as a position to be defocused in the force adjustment in the subsequent exposure process. . As already described, when “color exposure” is used instead of defocus exposure, information on the physical coordinates of the defect 16 is used as a position or position without performing exposure.
- step S207 Following the mask process (step S207) for introducing impurities into the source 11a and the drain l ib and ion implantation (step S208), deposition for loading the gate is performed (step S209), A photoresist mask for forming a contact hole is formed on the buried layer (step S210).
- FIG. 5B shows a state of the photoresist mask 18 exposed so that a contact hole is not formed at a location where the defect 16 exists.
- the photoresist mask 18 is formed by exposing so that only the region corresponding to the contact hole forming position of the photoresist uniformly coated on the gate loading layer 19 is opened.
- the region indicated by 18a in FIG. 5B originally corresponds to a region where an opening for forming a contact hole is to be provided, but a defect 16 exists at this position.
- the controller transmits the physical coordinate information of the defect to the exposure apparatus so as not to form an opening at the position (step S211), and the exposure apparatus determines the exposure condition for the defect existing area based on this information. Dummy exposure is performed so that a contact hole is not formed as a focus.
- FIGS. 6A and 6B are top plan views for explaining a situation where a short circuit between a word line and a contact hole is avoided by not forming a contact hole.
- the contact portion 14 In the conventional method in which the contact portion 14 is formed regardless of the presence or absence of the defect 16 (FIG. 6A), the contact portion 14 formed in the region where the defect 16 is present short-circuits the word line 13 and the bit line 15. As a result, the defect cannot be remedied with only bit line redundancy.
- the contact portion 14 (more specifically, a contact hole) is not formed in the region where the defect 16 exists.
- this flash memory is formed on the semiconductor substrate 11, the insulating layer 17 formed on the semiconductor substrate 11, and the insulating layer 17 A bit line 15 formed in the insulating layer 17, a contact portion 14 forming a contact between the bit line 15 and the semiconductor substrate 11, and a floating gate 12 and a word line 13 formed in the insulating layer 17.
- the contact portion 14 is regularly arranged, and includes a portion (a portion corresponding to reference numeral 16) in which the outside of the contour is not irregularly formed in the regular arrangement. Redundancy processing is applied to the bit line where the contact portion is not formed. According to the present invention, since it is possible to cope with only bit line redundancy, it is possible to provide a semiconductor device in which an operation failure is efficiently remedied.
- defect inspection is performed twice after the second gate etching step and after the sidewall deposition step, but it is appropriate depending on the process design of the device to be manufactured. Needless to say, it is provided only once.
