Definitions
- This disclosure relates to high-frequency circuits and semiconductor devices.
- Patent Document 1 discloses a filter in which a microstrip line is formed.
- This filter comprises a dielectric substrate, a microstrip conductive metal film formed on the front surface of the dielectric substrate, and a back surface metal film formed over the entire back surface of the dielectric substrate. Directly below the microstrip conductive metal film inside the dielectric substrate, multiple internal spaces are formed at predetermined intervals along the extension direction of the microstrip conductive metal film.
- One method of miniaturizing microwave and millimeter wave circuits is to make the substrate thinner.
- the substrate is thinned from 100 ⁇ m to 50 ⁇ m, for example, the width of the microstrip lines on the top surface of the chip can be reduced for the same characteristic impedance. This allows the area occupied by the matching circuit to be reduced.
- the conductive resin may creep up onto the top surface of the chip. This may make it difficult to mount with a high yield. Furthermore, conductive resin that creeps up onto the top surface of the chip may unintentionally short out the pattern, preventing the chip from functioning. Furthermore, conductive resin adhering to the pads may cause problems such as insufficient wire bond strength being obtained.
- the objective of this disclosure is to obtain a high-frequency circuit and semiconductor device that can prevent bonding material from creeping up onto the top surface of the substrate.
- the high-frequency circuit according to the present disclosure comprises a substrate and a signal line provided on an upper surface of the substrate, and a first protrusion is formed on the outer periphery of the back surface of the substrate opposite the upper surface along at least two opposing sides of the substrate.
- the first convex portion when the high-frequency circuit is mounted using a bonding material, can increase the distance from the application surface of the bonding material to the top surface of the substrate. This can therefore prevent the bonding material from creeping up onto the top surface of the substrate.

- Fig. 1 is a cross-sectional view of a high-frequency circuit 50 according to a first embodiment.
- Fig. 2 is a diagram for explaining the configuration of the back side of the high-frequency circuit 50 according to the first embodiment.
- the high-frequency circuit 50 is, for example, a micro/millimeter wave band MMIC (Monolithic Microwave Integrated Circuit) chip.
- the high-frequency circuit 50 includes a substrate 10 and a signal line 14 provided on an upper surface 11 of the substrate 10.
- the substrate 10 is, for example, a SiC substrate.
- the signal line constitutes, for example, a microstrip line.
- protrusions 16 are formed along each of the two opposing sides of the substrate 10.
- the substrate 10 is thinned, leaving only the portions along the two opposing sides that are the periphery of the circuit.
- no protrusions are formed along the other two sides of the outer periphery of the back surface 12 of the substrate 10 other than the two sides on which the protrusions 16 are formed.
- the length of one side of the high-frequency circuit 50 is, for example, 5 mm or less.
- the thickness of the thick portion of the substrate 10 is, for example, 100 ⁇ m to 200 ⁇ m.
- the thickness of the thinned portion of the substrate 10 is, for example, 50 ⁇ m or less, specifically 10 ⁇ m to 50 ⁇ m.
- the width of the protrusion 16 is, for example, about 50 to 200 ⁇ m.
- Pads 18 are provided on the side surfaces 17 of the substrate 10 corresponding to the two sides on which the protrusions 16 are formed.
- the pads 18 are DC or RF pads.
- the rear surface 12 of the substrate 10 is covered with a conductor layer 20 that serves as GND.
- FIG. 3 is a cross-sectional view of a high-frequency circuit 50a according to a first comparative example.
- FIG. 4 is a cross-sectional view of a high-frequency circuit 50b according to a second comparative example.
- the substrate 10a of the high-frequency circuit 50a has a thickness of 100 ⁇ m.
- a signal line 14 is provided on the upper surface of the substrate 10a.
- a conductor layer 20 serving as GND is provided on the rear surface of the substrate 10a.
- the substrate 10b of the high-frequency circuit 50b has a thickness of 50 ⁇ m.
- a signal line 14 is provided on the upper surface of the substrate 10b.
- a conductor layer 20 serving as GND is provided on the rear surface of the substrate 10b.
- the width of the signal line 14 will be smaller in the high-frequency circuit 50b, which has a thinner substrate 10b, and W1>W2.
- low-impedance lines are generally used for the output combining circuit in the final stage of a power amplifier. If the line width of the matching circuit can be reduced while maintaining the same characteristic impedance, the area of the output combining circuit can be reduced. This makes it possible to achieve a smaller overall MMIC.
- the convex portion 16 can increase the distance from the application surface of the bonding material, such as conductive resin, to the top surface 11 of the substrate 10.
- the substrate 10 is gripped by the two thick sides, ensuring the distance from the tip of the tweezers, collet, etc. to the application surface of the conductive resin. This can prevent the bonding material from creeping up onto the top surface 11 of the substrate 10 via the tweezers, collet, etc.
- the substrate 10 can be made thinner to reduce the size of the high-frequency circuit 50, and the high-frequency circuit 50 can be mounted with a high yield.
- the spread of the conductive resin can be confirmed from the two sides of the substrate 10 where the protrusions 16 are not formed. Therefore, it is possible to visually confirm that the die bonding has been performed reliably. Furthermore, by providing the pads 18 for DC or RF extraction on the side surface 17 of the substrate 10 instead of the top surface 11, the MMIC chip can be further miniaturized.
- the signal line will branch into multiple lines, such as a T-branch structure or a cross-branch structure, at the area where the characteristic impedance changes, specifically at the boundary between the locally thinned area and the thick part of the substrate. In such a case, parasitic components are added, and it may be difficult to achieve the performance in a terahertz wave band circuit.
- the central portion of the substrate 10 where the circuit is formed is uniformly thinned, as in this embodiment.
- a part of the signal line 14 is disposed directly above the convex portion 16.
- the signal line 14 directly above the convex portion 16 is a line or pad for applying a DC bias
- the effect of the change in the characteristic impedance of the signal line 14 on the circuit characteristics is generally small. This is because the RF signal component of interest is appropriately processed in the circuit or in a peripheral circuit outside the MMIC.
- the change in the characteristic impedance that is, the change in the distance between the signal line 14 and the GND conductor, may affect the characteristics. For this reason, it may be necessary to grasp the effect in advance by electromagnetic field simulation or the like and to carry out an appropriate design such as changing the signal line width.
- the convex portion 16 may be provided to avoid the portion where the circuit is formed, particularly the main line through which an RF signal passes or the RF probe pad.
- the signal line 14 directly above the protrusion 16 may be a line or pad for applying a DC bias.
- the heat dissipation of the transistors can be improved.
- the VH (via hole) diameter can be reduced, making it easier to further miniaturize the circuit.
- VHs are usually excavated by dry etching. For this reason, if the amount of excavation, i.e. the substrate thickness, is small, the VH diameter can be made smaller.
- FIG. 5 is a perspective view for explaining the configuration of the semiconductor device 100 according to the first embodiment.
- FIG. 6 is a side view of the semiconductor device 100 according to the first embodiment.
- FIG. 6 is a view of FIG. 5 as viewed from the A direction.
- the semiconductor device 100 includes a high-frequency circuit 50, a mounting substrate 60, and a protrusion 62 provided on the mounting substrate 60.
- the protrusion 62 is fitted between the convex portions 16 of the high-frequency circuit 50.
- the protrusion 62 has a shape corresponding to the recess in the rear surface 12 of the substrate 10.
- the upper surface 63 of the protrusion 62 is the bonding surface with the rear surface 12 of the high-frequency circuit 50, that is, the portion coated with the conductive resin.
- the mounting substrate 60 is also called a die-bond substrate.
- the semiconductor device 100 can ensure a large distance between the top surface 63 of the protrusion 62 and the top surface 11 of the substrate 10 of the high frequency circuit 50. This can prevent the conductive resin from being sucked up by tweezers or the like, allowing for high mounting yields.
- the height of the protrusion 62 is preferably about 50 ⁇ m longer than the recess dimension on the back surface 12 of the high frequency circuit 50. This allows most of the conductive resin that protrudes outside the chip to creep up on the mounting substrate 60 around the protrusion 62, rather than toward the tip of the tweezers or the like. This can sufficiently reduce the risk of the conductive resin creeping up onto the top surface of the chip.
- FIG. 7 is a perspective view explaining the configuration of a wafer 80 according to the first embodiment.
- FIG. 7 shows the state before the substrate 10 of this embodiment is separated into chips.
- the wafer 80 has protrusions 81 and 82, which are thick portions of the wafer 80.
- the protrusion 81 corresponds to the protrusion 16 of the high-frequency circuit 50.
- the width of the protrusion 81 is, for example, 100 to 400 ⁇ m.
- the protrusion 82 is a dummy portion provided for the purpose of reinforcing the strength and warping of the wafer 80.
- the width of the protrusion 82 is, for example, 100 to 400 ⁇ m.
- the wafer may warp, making it impossible to fix the wafer to the stage when inspecting its characteristics in the wafer state. In addition, it may become difficult to attach the wafer to tape and perform wafer dicing. Furthermore, if the wafer is fixed to a flat stage or the like in a warped state, the wafer may break or crack, resulting in a decrease in yield.
- the substrate thickness may be set to 30 ⁇ m or less. Achieving this substrate thickness with a wafer of 4 inches or more in diameter is even more difficult because, in addition to the problems of conductive resin creeping up and wafer warping, the wafer may crack when handled due to reduced strength.
- FIG. 8 is a diagram illustrating the state of the convex portion 81 of the wafer 80 according to the first embodiment before dicing.
- FIG. 9 is a diagram illustrating the state of the convex portion 81 of the wafer according to the first embodiment after dicing. In dicing, a dimension equivalent to the width of the dicing blade 90 used to cut the wafer 80 is removed. The width of the convex portion 81 in the wafer state is approximately the sum of the width of two convex portions 16 after dicing and the width of the dicing blade 90.
- the substrate 10 may be formed from a material other than SiC.
- the high frequency circuit 50 is not limited to an MMIC, but may be a matching circuit, a filter, etc.
- the bonding material for bonding the high frequency circuit 50 and the protrusion 62 is not limited to conductive resin, but may be solder, etc.
- the convex portions 16 are not limited to being formed on the two opposing sides of the substrate 10, but may also be formed on other sides. In other words, it is sufficient that the convex portions 16 are formed at least along each of the two opposing sides of the substrate 10.
- Fig. 10 is a cross-sectional view of a high-frequency circuit 250 according to the second embodiment.
- Fig. 11 is a diagram for explaining the configuration of the back surface side of a high-frequency circuit 250 according to the second embodiment.
- the location where the convex portion 216 is formed is different from that of the first embodiment.
- the other configurations are similar to those of the first embodiment.
- the convex portion 216 is formed along the four sides of the substrate 210 on the outer periphery of the back surface 12 of the substrate 210.
- the annular convex portion 216 is formed on the outer periphery of the substrate 210.
- the protrusions 216 can increase the distance from the surface on which the conductive resin is applied to the top surface of the substrate. This can prevent the bonding material from creeping up onto the top surface of the substrate 210. This allows the substrate 210 to be made thinner, the high frequency circuit 50 to be made smaller, and the high frequency circuit 250 to be mounted with a high yield. Note that in this embodiment, the outer periphery of the substrate 210 is made thick on all four sides, so the spread of the conductive resin can be confirmed by the conductive resin spilling out of the substrate 210. The conductive resin spilling out appears on the mounting substrate 60.
- FIG. 12 is a perspective view for explaining the configuration of a semiconductor device 200 according to the second embodiment.
- FIG. 13 is a side view of the semiconductor device 200 according to the second embodiment.
- the convex portion 216 provided along the four sides of the substrate 210 surrounds the protrusion 62 on the mounting substrate 60. This allows the high-frequency circuit 250 to be positioned, improving the positional accuracy of mounting.
- the direction in which the chip is gripped can be selected from two directions. Therefore, the effect of this embodiment can be obtained even when the direction in which the chip is gripped is restricted, such as when the mounting space is narrow.
- convex portions 216 are formed along the four sides of the substrate 210. Therefore, both convex portions 81 and 82 in the wafer 80 shown in FIG. 7 form convex portions 216.
- Fig. 14 is a cross-sectional view of a high-frequency circuit 350 according to the third embodiment.
- Fig. 15 is a diagram for explaining the configuration of the back side of the high-frequency circuit 350 according to the third embodiment.
- This embodiment differs from the second embodiment in that the pads 18 are not provided on the side surfaces of the substrate 210.
- the other configurations are the same as those of the second embodiment. In such a case, the pads 18 are disposed on the upper surface 11 of the substrate 210. Even if the pads 18 are not provided on the side surfaces 17, the effect of suppressing the creeping up of the resin is maintained.
- pads 18 are not provided on the side surface 17 of the substrate 210 in embodiment 2, but pads 18 do not have to be provided on the side surface 17 of the substrate 10 in embodiment 1.
- Embodiment 4. 16 is an enlarged view of a radio frequency circuit 450 according to the fourth embodiment.
- an RF pad 418 is provided directly on the protrusion 16, not on the side surface 17 of the substrate 10.
- the other configurations are the same as those of the first embodiment. This makes it possible to reduce the capacitance between the RF pad 418 and the conductor layer 20, thereby improving the accuracy of on-wafer measurement.
- the RF pad 418 becomes the electrode pad of the transistor.
- the performance of the transistor can be improved by reducing the pad capacitance.
- pads may be provided both on the side surface 17 of the substrate 10 and directly above the protrusion 16.
- Fig. 17 is an enlarged view of a high-frequency circuit 550 according to the fifth embodiment.
- the convex portion 16 is formed inside the outermost periphery of the rear surface 12 of the substrate 510.
- the substrate 510 has a thinned inner recess 522 outside the convex portion 16.
- the inner recess 522 is a portion indicated by a length L1 in Fig. 17.
- the other configurations are the same as those of the fourth embodiment.
- the substrate 510 can be made thinner at the cut portion by dicing. Therefore, dicing can be easily performed.
- the distance from the tip of the tweezers, collet, etc. to the surface to which the conductive resin is applied can be further increased. Therefore, creeping up of the conductive resin can be further suppressed.
- Embodiment 6. 18 is a diagram illustrating the configuration of the back side of a high-frequency circuit 650 according to embodiment 6.
- a convex portion 624 is further formed in the center of the back surface 12 of the substrate 610.
- the other configurations are similar to those of embodiment 1.
- the convex portion 624 extends from one convex portion 16 to the other convex portion 16, for example, in the center of the substrate 610 in the longitudinal direction.
- the effect of suppressing warping of the wafer can be improved. According to this embodiment, it is possible to suppress a decrease in the strength of the chip, particularly when the thinned region is large. Furthermore, when the aspect ratio of the length and width of the chip is large, it is possible to suppress a decrease in the strength of the chip by forming a protrusion 624 midway along the long side of the chip.
- FIG. 19 is a diagram illustrating the configuration of the back side of a high-frequency circuit 750 according to a modified example of embodiment 6.
- a convex portion 624 is formed in the center of the back side 12 of the substrate 710.
- the convex portion 624 of this embodiment is not limited to the convex portion 16 of embodiment 1, and may be combined with the convex portion 216 of embodiment 2.
- Fig. 20 is a cross-sectional view of a high-frequency circuit 850 according to the seventh embodiment.
- Fig. 21 is a diagram for explaining the configuration of the back side of the high-frequency circuit 850 according to the seventh embodiment.
- a hole 826 is formed on the back surface 12 of the substrate 810 directly below the edge of the signal line 14.
- the hole 826 is filled with a metal 828.
- the other configuration is the same as that of the second embodiment.
- the hole 826 has a diameter of, for example, 15 ⁇ m.
- the multiple holes 826 are formed at intervals of approximately 35 ⁇ m.
- the substrates according to the first to sixth embodiments are sufficiently thin except for the peripheral portions.
- holes 826 are further formed directly under the edge of the signal line 14 where the electric field concentrates in the microstrip line, and the substrate 810 is engraved. This further increases the capacitance between the substrate 810 and the signal line 14, allowing the low characteristic impedance line to be used as a matching circuit.
- the 1/4 wavelength is approximately 250 ⁇ m. In this case, by arranging five pairs, or 10 or less holes 826, a matching circuit using a 1/4 wavelength ultra-low impedance microstrip line can be realized.
- holes 826 filled with metal 828 are arranged, but it is also possible to adjust the characteristic impedance by using holes 826 that are not filled with metal 828. Note that holes 826 may be formed in the substrate 10 of embodiment 1, not limited to embodiment 2.
