Aspects of the present disclosure relate to determining a layout of a racetrack that forms part of a radio frequency (RF) isolation structure of a packaged module and forming the resulting RF isolation structures. Based on electromagnetic interference data for a module, an area of the module that is less sensitive to external radiation is identified. A racetrack layout can be determined based on identifying the area that is less sensitive to external radiation. The racetrack layout can include a narrowed section in the area that is less sensitive to external radiation or a break in the area that is less sensitive to external radiation.

대표청구항 ▼

1. A method of determining a racetrack layout, the method comprising: obtaining electromagnetic interference data for a module, the electromagnetic interference data being associated with an electromagnetic probe;identifying an area of the module that is less sensitive to external radiation than another area of the module based on the electromagnetic interference data, the module including a radio frequency component coupled to a major surface of a substrate; anddetermining a racetrack layout based on said identifying, the racetrack being disposed such that the major surface of the substrate is between the racetrack and the radio frequency component, the racetrack and a conductive layer forming a portion of a radio frequency isolation structure around the radio frequency component, and the radio frequency component being disposed between the conductive layer and the major surface of the substrate. 2. The method of claim 1 wherein the racetrack layout includes a narrowed section in the area of the module that is less sensitive to external radiation. 3. The method of claim 1 wherein the racetrack layout includes a break in the area of the module that is less sensitive to external radiation. 4. The method of claim 1 wherein said identifying includes identifying areas of the module that are more sensitive to external radiation and areas of the module that are less sensitive to external radiation based on the electromagnetic interference data. 5. The method of claim 1 wherein said identifying includes identifying a second area of the module that is less sensitive to external radiation than the another area of the module. 6. The method of claim 5 wherein the racetrack layout includes at least one of a break or a narrowed section in the second area. 7. The method of claim 5 wherein the racetrack layout includes a break in the first area and a narrowed section in the second area. 8. The method of claim 1 wherein said obtaining includes performing the electromagnetic probe. 9. The method of claim 1 wherein the electromagnetic interference data corresponds to the module without the radio frequency isolation structure. 10. The method of claim 1 wherein the electromagnetic interference data corresponds to the module with a different racetrack layout than the racetrack layout. 11. The method of claim 1 further comprising iterating said identifying and said determining. 12. The method of claim 1 further comprising determining a second racetrack layout based on said identifying, the second racetrack being disposed in a different layer of the substrate than the racetrack. 13. The method of claim 1 further comprising forming the racetrack layout. 14. The method of claim 8 wherein the racetrack layout has at least one of a break or a narrowed section in the area of the module that is less sensitive to external radiation. 15. The method of claim 14 further comprising forming the racetrack layout. 16. The method of claim 8 wherein the racetrack layout has a break in the area of the module that is less sensitive to radiation. 17. The method of claim 8 wherein the racetrack layout has a narrowed section in the area of the module that is less sensitive to radiation. 18. A non-transitory computer readable medium comprising instructions that, when executed by a one or more processors, causes a method of determining a racetrack layout to be performed, the method including: obtaining electromagnetic interference data for a module, the electromagnetic interference data being associated with an electromagnetic probe;identifying an area of the module that is less sensitive to external radiation than another area of the module based on the electromagnetic interference data, the module including a radio frequency component coupled to a major surface of a substrate; anddetermining a racetrack layout based on said identifying, the racetrack being disposed such that the major surface of the substrate is between the racetrack and the radio frequency component, the racetrack and a conductive layer forming a portion of a radio frequency isolation structure around the radio frequency component, and the radio frequency component being disposed between the conductive layer and the major surface of the substrate. 19. The non-transitory computer readable medium of claim 18 wherein the racetrack layout has at least one of a break or a narrowed section in the area of the module that is less sensitive to external radiation. 20. The non-transitory computer readable medium of claim 18 wherein the method further includes iterating said identifying and said determining.
