- “Signal that is a source of noise” refers to a signal that contains unwanted noise components and that the signal itself may contain noise, but for other signals the signal becomes noise.
- the “periphery” means a portion where electrode terminals adjacent in the vertical and horizontal directions are arranged when the electrode terminals are arranged in a matrix, and further electrode terminals adjacent in the oblique direction are arranged. Sometimes a location is included.
- the noise component is removed by the electrode terminal having low impedance, and unnecessary signal wraparound to the outside of the electrode terminal having low impedance can be reduced.
- the electrode terminal for inputting / outputting a signal having low noise resistance and the electrode terminal for inputting / outputting a signal as a noise generation source are separated from each other by an electrode terminal having a low impedance. .
- Signals with low noise tolerance means that semiconductor devices are mixed with noise. Means a signal that malfunctions or deteriorates its characteristics. Since the noise component of the signal that is the source of noise is reduced by the low impedance electrode terminal, it is possible to reduce mixing into signals with low noise immunity.
- An electrode terminal having a low impedance may be arranged around an electrode terminal for inputting / outputting a signal having low noise resistance.
- the interval between the electrode terminal for inputting / outputting a signal that is a source of noise and the electrode terminal for inputting / outputting a noise-resistant low-level signal is at least twice the unit interval between adjacent electrode terminals. You may arrange

- a semiconductor device includes a circuit that generates a switching signal.
- a signal that is a source of noise is a switching signal, and a signal with low noise tolerance generates a reference voltage in the semiconductor device. It may be a signal that is necessary to achieve this.
- a circuit block for generating a reference voltage and a block for generating a switching signal may be separately supplied with power supply voltages in consideration of signal wraparound.
- the circuit electrode is stabilized by electrically shielding the electrode terminal for the signal necessary for generating the reference voltage with the electrode terminal for the switching signal and the electrode terminal with a low impedance. Low noise can be achieved.
- the semiconductor device may include a switching regulator control circuit, and the signal serving as a noise generation source may be a switching signal output from the switching transistor of the switch in- glelator.
- the “switching regulator” means that the switching transistor connected in series or in parallel with the input voltage source is turned on and off to control the current supplied to the inductor and the capacitor to perform energy conversion, and to change the input voltage.
- An inductor and a capacitor for performing energy conversion and smoothing an output voltage are often provided as external components, and there is a circuit in which up to a switching transistor is integrated inside a semiconductor device.

- FIG. 1 is a plan view of an electrode terminal side force of semiconductor device 100 according to the embodiment of the present invention.
- the semiconductor device 100 has a BGA structure, and a plurality of electrode terminals for inputting / outputting signals to / from the outside are provided in a matrix.
- the noise generation source electrode terminal 10 is an electrode terminal for inputting / outputting a signal as a noise generation source.
- the low impedance electrode terminal 12 is an electrode terminal that is adjacent to the noise source electrode terminal 10 in the vertical or horizontal direction and has a low impedance.
- the low impedance electrode terminal 14 is an electrode terminal that is adjacent to the noise source electrode terminal 10 in an oblique direction and has a low impedance.
- FIG. 2 is a cross-sectional view taken along line 2-2 of FIG.
- This semiconductor device 100 has a WL-CSP structure in which a connection electrode with the outside is directly formed on a semiconductor wafer.
- the semiconductor device 100 includes a silicon wafer 20, a passivation 22, a pad 24, an insulating resin layer 26, a rewiring 28, a post 30, a solder bump 32, and a sealing resin 34.
- a semiconductor integrated circuit including elements such as transistors is formed on the silicon wafer 20, and a node 24 for signal input / output is provided.
- the pad 24 is usually formed of a material such as aluminum.
- the nosiculation 22 is a silicon nitride film or the like, and is formed by opening the upper part of the pad 24.
- the rewiring 28 routes the signal from the position of the pad 24 to the position of the solder bump 32 that becomes the final electrode terminal formation position, and connects to the post 30.
- the post 30 is formed of copper or the like, and electrically connects the solder bump 32 and the rewiring 28.
- FIG. 3 shows a circuit diagram of an equivalent model of electrode terminals.
- Noise source electrode terminal 10 and low It is assumed that the above-described parasitic capacitance C between the posts exists between the impedance electrode terminals 12 and the complex impedance of the low impedance electrode terminal 12 is given by ⁇ ( ⁇ ) as a function of the frequency ⁇ .
- a noise source 16 is connected to a noise source electrode terminal 10 for inputting / outputting a signal as a noise source, and its voltage is VI and frequency is ⁇ .
- V2 ⁇ ( ⁇ ) ⁇ (1Zj ⁇ C + Z (co)) XVI holds. Therefore, the smaller the impedance ⁇ ( ⁇ ) of the low impedance electrode terminal 12 is, that is, the lower the impedance is, the smaller the voltage V2 appearing at the low impedance electrode terminal 12 is. The signal that goes around to the low impedance electrode terminal 12 becomes smaller.
- the low impedance electrode terminal 12 adjacent to the noise generation source electrode terminal 10 in the vertical and horizontal directions is set to low impedance.
- the impedance of an electrode terminal means the impedance desired for the electrode terminal when the semiconductor device 100 is mounted on a printed circuit board and peripheral circuit components are mounted and in an operating state. Therefore, a grounded electrode terminal or an electrode terminal connected to the ground potential by a capacitor having a large capacitance has a low impedance.
- the input impedance is high and the output impedance is low, but even if it is designed to be high impedance at the input terminal of a circuit block, a capacitor with a large capacity such as a bypass capacitor is used.
- the low impedance electrode terminal 12 When it is connected to the ground potential, it can be said to be low impedance.
- the impedance here means complex impedance. Therefore, it is desirable that the low impedance electrode terminal 12 is set to have a low AC impedance particularly in the frequency band of the signal for which wraparound is to be reduced.
- the low impedance electrode terminal 12 adjacent to the noise generation source electrode terminal 10 for inputting / outputting a signal as a noise generation source in the vertical and horizontal directions has a low impedance. Since the voltage V2 appearing at the low-impedance electrode terminal 12 in the circuit diagram of FIG. 3 is reduced, signal wraparound to other electrode terminals can be reduced.
- the low impedance electrode terminal 14 obliquely adjacent to the noise generation source electrode terminal 10 is set to low impedance as necessary.
- Low impedance electrode terminal 14 is noise Adjacent to the electrode terminal for inputting / outputting a signal which is a generation source of the above-mentioned diagonally. Since the parasitic capacitance between the electrode terminals is determined by the distance d between the posts, the impedance of the low impedance electrode terminal 14 is set low for a semiconductor device in which the electrode terminals are densely arranged. Further, noise wraparound can be reduced more suitably.
- Electrode terminal 18 in Fig. 1 is an electrode terminal for signals with low noise immunity, and is surrounded by a low-impedance electrode terminal that is adjacent to electrode terminal 18 in the vertical or horizontal direction and has a low impedance. 12 'is arranged. Furthermore, the impedance of the electrode terminal 18 ′ for the signal having low noise immunity and the electrode terminal 14 ′ obliquely adjacent to the signal terminal 18 ′ is set as low as necessary.
- the distance between the noise source electrode terminal 10 and the signal electrode terminal 18 with low noise resistance is sufficiently long compared to the unit distance d between adjacent electrode terminals indicated by d in the figure. More preferably, noise contamination and crosstalk can be reduced.

- the control unit 90 is a circuit for controlling the entire operation of the semiconductor device 100, and the power supply device is switched on and off by a control signal input to the CNT1 to CNT3 terminals.
- the signals input to the MODE pin and the CNT1 to CNT3 pins are level signals that take a low, high or low level.

- GNDP pin and G Since the ND2 terminal is connected to the ground potential, the impedance is very low. Also, the impedance of the BATP terminal connected to the battery 80 is low because the internal impedance of the battery is low and it is grounded by the bypass capacitor 82.
- the LDOOUT terminal from which the voltage of the linear regulator 50 is output is connected to the capacitor C1 via an external wiring. Since the capacitance value of the capacitor C1 is provided to smooth the output voltage Vout, the capacitance value is sufficiently large. Therefore, the LDOO UT terminal is also low impedance. Similarly, the FBIN terminal to which the output voltage Vout is fed back is also connected to the capacitor C1, so its impedance is low.

Therefore, since the reference voltage Vref has a great influence on the characteristics of the power supply device, high stability is required. If noise enters the VREF1 and VREF2 pins to which a bypass capacitor is connected to stabilize the reference voltage source 70, generation of an accurate reference voltage Vref is prevented. Therefore, the VREF1 and VREF2 terminals can be regarded as electrode terminals for inputting and outputting signals with low noise immunity. As shown in Figure 5, the VREF1 and VREF2 pins are separated from the SWOUT pin by a low impedance pin. These terminals are placed as far away as possible.
- the VREF1 and VREF2 terminals have low noise properties
- the signals at the MODE terminal and the CNT1 to CNT3 terminals are highly resistant to noise. These pins take either high level or low level values, so even if noise is mixed, the effect on circuit operation is extremely small. Therefore, by placing a low impedance electrode terminal around the SWOUT terminal and arranging the MODE terminal and the CNT1 to CNT3 terminals around it, the VREF1 and VREF2 terminals are moved away from the SWOUT terminal and the signal wraps around. Reducing Can do.

- the reference voltage Vref can be generated with high accuracy. Since the output voltage Vout of the power supply 200 is stabilized to (R1 + R2) ZR1 X Vref by feedback, the stability of the output voltage Vout of the power supply 200 is achieved by generating the reference voltage Vref with high accuracy. Can be increased.
