Description

Wafer surface LD type development linear photoresist defect monitoring method and monitoring system
Technical Field
The invention relates to the field of semiconductor production and manufacturing, in particular to a wafer surface LD type development linear photoresist defect monitoring method in a semiconductor development process. The invention also relates to a wafer surface LD type development linear photoresist defect monitoring system in the semiconductor development process.
Background
The increase in memory density of memory devices is closely related to the progress of semiconductor manufacturing processes. As the aperture of a semiconductor manufacturing process becomes smaller, the memory density of a memory device becomes higher. In order to further increase the memory density, a memory device of a three-dimensional structure (i.e., a 3d memory device) has been developed. The 3d memory device includes a plurality of memory cells stacked in a vertical direction, can increase integration in multiples on a unit area of a wafer, and can reduce cost.
With the gradual development of the 3d process, the thickness of the photoresist needs to be increased in the step process to improve the step number which can be manufactured by a single etching process, thereby improving the process stability and reducing the process load and the process cost. As the photoresist thickness increases, the development requirements also increase. At present, the developing process is mainly performed by using an LD type developing nozzle through a forward scanning method. The LD type nozzle starts from one side of the wafer, scans from the other side at a constant speed, and continuously sprays liquid. An Iline machine is generally selected at a level with larger line width, an LD type spray head is selected when the line width is matched with a Track machine for developing, and the uniformity in the plane is adjusted simply and is easy to control. However, the photoresist used in the operation of the iline machine is relatively thick, the LD-type nozzle is relatively close to the wafer during the development process, and is easily contaminated, and linear photoresist defect residues are formed on the surface of the wafer during the development process, as shown in fig. 1, which affects the yield of the product. The existing LD type development defect monitoring is machine PDM monitoring, which is post-monitoring, that is, the residual of linear photoresist defects is deduced reversely by finding the defects of products. The existing monitoring method is not beneficial to production, and can cause a large amount of defective products in high-speed production.
Disclosure of Invention
In this summary, a series of simplified form concepts are introduced that are simplifications of the prior art in this field, which will be described in further detail in the detailed description. This summary of the invention is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter.
The invention aims to provide a wafer surface LD type developing linear photoresist defect monitoring method which can carry out active monitoring on linear photoresist defect residues in advance.
Another technical problem to be solved by the present invention is to provide a wafer surface LD type developed linear photoresist defect monitoring system capable of performing active monitoring on linear photoresist defect residues in advance.
In order to solve the above technical problems, the method for monitoring the defects of the LD-type developed linear photoresist on the surface of the wafer according to the present invention comprises:
s1, triggering automatic optical detection to the developing LD type nozzle periodically; the detection period is selected according to actual production requirements;
s2, judging whether the LD type spray head is polluted or not through automatic optical detection, and if not, normally producing the machine;
s3, if the pollution happens, triggering the LD type spray head to clean;
and S4, performing automatic optical detection again after cleaning, judging whether pollution occurs, if no pollution occurs, triggering the machine to produce, otherwise, performing cleaning again until the automatic optical detection is pollution-free.
AOI (Automated Optical Inspection abbreviation) is called automatic Optical Inspection, and is an automatic Inspection based on the principle that when an apparatus for inspecting defects of production equipment is automatically inspected, a machine automatically scans through a camera, acquires images, inspects the defects through image processing, and displays/marks the defects through a display or an automatic mark for repair personnel to repair.
Optionally, the method for monitoring the defects of the wafer surface LD type developing linear photoresist is further improved, and if the contamination is still detected after more than three times of cleaning of the LD type spray head, an alarm is triggered and manual review is carried out.
If the LD type sprayer is still detected to be polluted after more than three times of cleaning, the pollution is probably not caused by the sprayer pollution and is probably caused by other reasons, so that the machine needs to be stopped for manual review, and the larger loss is avoided.
Optionally, the method for monitoring the LD-type developed linear photoresist defects on the wafer surface is further improved, and if the total time for executing the method for monitoring the LD-type developed linear photoresist defects on the wafer surface is longer than a preset threshold, an alarm is triggered and manual review is performed.
If the total time of the method for monitoring the LD type developed linear photoresist defects on the surface of the wafer is longer than a preset threshold (for example, the time for completely performing the pollution detection plus three times of cleaning), the monitoring of the invention still finds that the pollution starts the cleaning cycle to be performed, which indicates that the pollution may not be caused by the pollution of the spray head, and may be caused by other reasons, so that the machine needs to be stopped for manual review, and the larger loss is avoided.
Optionally, the method for monitoring the LD-type developed linear photoresist defects on the wafer surface is further improved, and is suitable for vacuum cavity wafer transfer structures of semiconductor production machines with processes of 130nm, 90nm, 65nm, 55nm, 45nm, 40nm, 32nm, 28nm, 65nm and less than 22 nm.
Optionally, the method for monitoring the LD type developed linear photoresist defects on the surface of the wafer is further improved, and is suitable for vacuum cavity wafer transmission structures of logic semiconductor devices, storage semiconductor devices, radio frequency semiconductor devices, analog semiconductor devices, MEMS, CIS, Flash and eFlash process semiconductor production machines.
In order to solve the above technical problems, the present invention provides a wafer surface LD type developed linear photoresist defect monitoring system, which is integrated in a semiconductor manufacturing machine, comprising:
an automatic optical inspection unit (AOI) disposed beside the LD type showerhead for inspecting whether contamination occurs in the LD type showerhead;
a detection control unit for controlling the automatic optical detection unit to periodically perform detection on the LD-type head, which decides whether to trigger the LD-type head cleaning according to the detection structure of the automatic optical detection unit;

and an LD type head cleaning unit controlled by the detection control unit to perform cleaning on the LD type head.
Optionally, the system for monitoring the defects of the LD-type developed linear photoresist on the wafer surface is further improved, and if the automatic optical detection unit still detects contamination after the LD-type nozzle cleaning unit performs LD-type nozzle cleaning for more than three times, the detection control unit triggers an alarm to perform manual review.
Optionally, the wafer surface LD type developed linear photoresist defect monitoring system is further improved, and if the total time of single operation of the defect monitoring system is greater than a preset threshold, an alarm is triggered and manual review is performed.
Optionally, the system for monitoring the LD type developed linear photoresist defects on the wafer surface is further improved, and is suitable for vacuum cavity wafer transmission structures of semiconductor production machines with the processes of 130nm, 90nm, 65nm, 55nm, 45nm, 40nm, 32nm, 28nm, 65nm and below 22 nm.

The invention improves the scheme of obtaining wafer linear photoresist defect residues by backward derivation of after-monitoring in the prior art into actively monitoring the LD type spray head pollution in advance, can actively find the source of linear photoresist defect residues, and cleans in advance to avoid the linear photoresist defect residues to the maximum extent.
