Support matrix with bonding channel for integrated semiconductors, and method for producing it
View Patent ↗Support matrices for semiconductors are often encapsulated in a region of the bonding leads, the so-called bonding channel. The encapsulation is effected using a dispensable material that can flow onto the support matrix and causes contamination there. In order to prevent this flow, the support matrix for integrated semiconductors has a frame, conductor track structures and at least one bonding channel. In the bonding channel bonding leads or wires for connecting the conductor track structures to the integrated semiconductor are disposed. Disposed along the edge of the bonding channel a barrier for preventing the flow of flowable material from the bonding channel onto the frame and/or the conductor track structures. A method for producing such support matrices is likewise disclosed.
1. A support matrix for integrated semiconductors, comprising:
a frame having at least one bonding channel with an edge formed therein, said frame further having a groove formed therein along said edge of said bonding channel;
conductor track structures disposed on said frame, said groove formed in said frame functioning as a barrier for preventing a flow of a flowable material from said bonding channel onto said frame and onto said conductor track structures, said barrier having a region with a parting agent disposed thereon for repelling the flowable material; and
contacts, selected from the group consisting of bonding leads and wires, connected to said conductor track structures and disposed in said bonding channel, said contacts used for connecting said conductor track structures to an integrated circuit.
2. The support matrix according to claim 1 , wherein said barrier is disposed on all sides of said bonding channel and completely surrounds said bonding channel.
3. The support matrix according to claim 1 , wherein said frame has a surface remote from said bonding leads and said barrier is formed in said surface of said frame which is remote from said bonding leads.
4. The support matrix according to claim 1 , wherein the flowable material is silicone for forming structures on the support matrix.
5. The support matrix according to claim 1 , wherein said barrier has a region with a parting agent disposed thereon for repelling the flowable material.
6. A support matrix for integrated semiconductors, comprising:
a frame having at least one bonding channel with an edge formed therein;
conductor track structures disposed on said frame, said frame and said conductor track structures having a groove formed therein along said edge of said bonding channel, said groove functioning as a barrier for preventing a flow of a flowable material from said bonding channel onto said frame and onto said conductor track structures, said barrier having a region with a parting agent disposed thereon for repelling the flowable material; and
contacts, selected from the group consisting of bonding leads and wires, connected to said conductor track structures and disposed in said bonding channel, said contacts used for connecting said conductor track structures to an integrated circuit.
7. The support matrix according to claim 6 , wherein said groove is formed to extend into said bonding leads.
8. A support matrix for integrated semiconductors, comprising:
a frame having at least one bonding channel with an edge formed therein;
conductor track structures disposed on said frame;
contacts, selected from the group consisting of bonding leads and wires, connected to said conductor track structures and disposed in said bonding channel, said contacts used for connecting said conductor track structures to an integrated circuit; and
a barrier formed along said edge, said barrier having a parting agent disposed thereon for repelling a flowable material from said bonding channel onto said frame and onto said conductor track structures.
