Abstract

PURPOSE:To make possible the discrimination of the products of semiconductor integrated circuits clearly add simply and to dispense with high technicians by a method wherein patterns for discriminating the products are respectively formed on the surface of each semiconductor integrated circuit. CONSTITUTION:A pattern region 3 for discriminating a product is set at a position, where a region 1 constituting an electronic circuit does not overlap with bonding pad regions 2 in a semiconductor integrated circuit, or at a position which exerts no effect on the constitution of a real pattern within the region 1 and the regions 2. Moreover, in the process treatment of patterns 4 for discriminating the product, a process for clarifying the forms of the patterns is used and the patterns 4 are constituted of discriminable characters or graphic forms by the arrangement of a group of the characters or graphic forms. In such a way, as the patterns for discriminating the product are provided in the integrated circuit, the function and kind of the circuit are judged clearly and simply, high technicians become unnecessary and the flow of the product becomes possible correctly and in a short time.

Description

[Detailed description of the invention] [Industrial application fields] The present invention relates to a pattern shape of a semiconductor integrated circuit.

[Summary of the Invention] The present invention provides a process for manufacturing a semiconductor integrated circuit, in which a pattern remaining on a semiconductor substrate as a result of processing in the manufacturing process includes a pattern for identifying the product, in addition to the pattern constituting the electronic circuit. By incorporating elements that can differentiate products from other products, we have achieved a harmonious combination of human abilities required for product judgment, while at the same time reducing costs by shortening judgment time and improving quality by accurate process flow. It is something.

[Prior Art] In a conventional semiconductor integrated circuit, only a pattern constituting an electronic circuit exists on a semiconductor substrate.

[Problem M to be solved by the invention] However, in the above-mentioned conventional technology, when identifying a semiconductor integrated circuit as a product, it is determined by recognizing part or all of the electronic circuit configured on the semiconductor substrate. However, there are problems in that it takes a lot of judgment time and requires the input of human resources with advanced technology for circuit recognition in order to carry out accurate flow in the manufacture and commercialization of semiconductor integrated circuits.

SUMMARY OF THE INVENTION The present invention is intended to solve these problems, and its purpose is to provide semiconductor integrated circuits that meet product specifications in a short delivery time.

[Means for Solving the Problems] The semiconductor integrated circuit of the present invention includes adding not only a pattern constituting an electronic circuit to a pattern remaining on a semiconductor substrate, but also a pattern that can be clearly identified as a product. Features.

[Embodiment] FIG. 1 is a plan view of a semiconductor integrated circuit showing one embodiment of the present invention.

Reference numeral 1 indicates an area constituting an electronic circuit of a semiconductor integrated circuit, 2 indicates an area of a bonding pad for input/output of the electronic circuit, and 3 indicates a pattern area for identifying a product.

FIG. 2 is an enlarged view of 5 in FIG.

The pattern area for identifying the product shown in FIG. 1 is located at a position that does not overlap with the area constituting the electronic circuit and the bonding pad area in the semiconductor integrated circuit, or the area constituting the electronic circuit and the bonding pad area. Set it in a position that does not affect the actual pattern structure within the pattern.

The pattern for identifying the product shown in FIG. 2 uses a step in which the shape becomes clear during processing, and is made up of characters or patterns that can be identified by the arrangement of a group of figures.

By having a pattern in the semiconductor integrated circuit that identifies the product, the function and type of the semiconductor integrated circuit can be determined clearly and easily, and products can be moved accurately and in a short time without requiring highly skilled personnel. It becomes possible.

[Effects of the Invention] As described above, according to the present invention, by forming a pattern for identifying the product on the surface of the semiconductor integrated circuit, product identification of the semiconductor integrated circuit can be clearly and easily performed. This has the effect of shortening the delivery time due to the reduction in the time required for identification, and lowering costs due to the fact that the personnel engaged in identification does not require advanced technology (reducing personnel expenses).
