The sealing ring structure provided by the invention can prevent hydrosphere from penetrating, can reduce influence on an integrated circuit from the noises transferred by the sealing ring, can reduce noise coupling, and can prevent an electromagnetic signal from interfering the operation of a sensitive circuit and the like; and the structure is simple, the processing is convenient, and the sealing ring structure has strong practicability and can be widely popularized and applied.
Description
Technical field
The present invention relates to a kind of seal ring structure, specifically, relate to a kind of seal ring structure that is used for IC chip.
Background technology
Integrated circuit all is on silicon chip or other semiconductor material substrate, to make usually, carries out packaging and testing then.When encapsulation, must cut (saw) to integrated circuit earlier.The mechanical force of cutting possibly cause edge to form micro-fractures, especially near edge.Formed slight crack may advance towards the central circuit zone of integrated circuit and cause circuit region wherein to damage.In order to protect the circuit region of IC Center, generally can on the IC chip between circuit region with and Cutting Road between, configuration sealing ring (seal ring).Sealing ring can prevent that any slight crack (slight crack that for example, is caused because of the stress (stress) of cutting during integrated circuit) from invading the circuit region of IC interior.In addition, sealing ring also can avoid moisture to infiltrate, or avoids other chemical substance to get into and the circuit region of damage IC interior.
Traditional sealing ring is by the substrate that mixes, the circulus that metal connecting line and through hole and dielectric material are formed.Though this sealing ring can prevent slight crack and moisture that chip cutting produces and infiltrate; But it may conduct noise to other circuit in the different circuit regions or conduct the integrated circuit of external disturbance electromagnetic riveting machine signal to chip internal, and then has influence on the running of whole integrated circuit.As far as radio frequency chip, because it has low noise amplifier (LNA), the The noise of being come pressure sealing ring to propagate more easily.
In order to suppress propagation of noise, used the sealing ring of some intermittent interruption to solve this problem at present; Though it helps to reduce propagation of noise, there is certain risk in reliability.Especially under some rigorous environment conditions, the inside that aqueous vapor can get into IC chip via the interruptions of sealing ring makes the chip accelerated ageing.
Summary of the invention
To the problems referred to above that prior art exists, the purpose of this invention is to provide and a kind ofly both can prevent penetrating of aqueous vapor, can reduce the noise that comes the pressure sealing ring transmission the seal ring structure that is used for IC chip again to the integrated circuit influence.
For realizing the foregoing invention purpose, the technical scheme that the present invention adopts is following:
A kind of seal ring structure that is used for IC chip; It is characterized in that: at least one side of said sealing ring is a bilateral structure, and the inner side edge at least one bilateral structure (side adjacent with the integrated circuit on the chip) is provided with at least 1 opening.
As a kind of preferred version, the adjacent dual-side of said sealing ring is bilateral structure, and is equipped with 2 openings on the inner side edge in each bilateral structure.
As another kind of preferred version, the relative dual-side of said sealing ring is bilateral structure, and is equipped with 2 openings on the inner side edge in each bilateral structure.
As further preferred version, said sealing ring is a twin nuclei, and outer shroud wherein is a closed loop, and interior ring wherein adopts said structure.
As further preferred version, the section that is disconnected because of opening at least one inner side edge is connected with ground pads through metal wire.
Compared with prior art, the present invention is made as bilateral structure through at least one side with sealing ring, and with chip on adjacent at least one inner side edge of integrated circuit on be provided with at least 1 opening; Realized both can preventing penetrating of aqueous vapor, can reduce again and come the influence of noise that pressure sealing ring transmits, can reduce coupling noise integrated circuit; Prevent that electromagnetic riveting machine signal from disturbing sensitive circuit running etc., and simple in structure, easy to process; Have extremely strong practicality, but wide popularization and application.
