摘要:
A method is disclosed for identifying a physical failure location on an IC without using layout-versus-schematic (LVS) verification tool. In the method, the integrated circuit is tested with one or more test patterns to identify a failure port thereon. Hierarchical information of the failure port is generated through the test patterns. A physical location of the failure port in a layout of the integrated circuit is identified through a relation between the hierarchical information and a floor plan report. Layout information of a routing path associated with the physical location of the failure port is retrieved from a layout database.

First, a wafer with a plurality of defects generated in a first semiconductor process is provided. A defect inspection is performed to detect the defects on the wafer. Then, an automatic defect classification is performed according to a predetermined defect database having a defect classification recipe generated from a second semiconductor process. After that, a verifying process is further performed by comparing the result of the automatic defect classification with that of a manual defect classification to verify the accuracy of the automatic defect classification.
摘要:
A method of fabricating ROM products through the use of embedded flash/EEPROM prototypes is disclosed. This is accomplished by first forming a Flash/EEPROM prototype, performing programming simulations on the prototype, developing a ROM code and mask, and then forming a ROM product in the same manufacturing line by skipping certain Flash/EEPROM steps and then implanting the ROM code into the final ROM product. The method improves turn-around-time in the manufacturing line, and reduces cost to the customer. A method of doing business is also disclosed directed to providing ROM products to a customer without much redesign time and effort on the part of the customer.
