[Previous technology] Semiconductor packages mainly have four functions, including: signal connection, power connection, heat dissipation, and protection. Generally speaking, a semiconductor wafer is first formed into an enclosing body, such as a single-chip module (SCM) or a chip carrier, which is referred to as a first-stage package, that is, a semiconductor package. These packaged chips, along with other components, such as capacitors, resistors, poles, filters, switches, optical components, and RF components, are packaged in a second-stage package and assembled on a printed circuit board.
隨著半導體晶片之工作頻率的增高、元件密度的增 加,以及工作電壓的下降,半導體封裝所產生的雜訊問題 越趨嚴重。更明確而言,當半導體晶片上的元件在開啟 (on)與關閉(〇 f f)間切換時,基板間的電源及接地面所產 生的同時切換雜訊(Simultaneous Switch Noise ;SSN)便 會大幅度的降低整體半導體封裝構造的效益,亦即降低整 個系統的效益。為了解決上述同時切換雜訊的問題,半導 體封裝構造之同時切換雜訊必須被量測以及分析,以改良 半導體封裝構造以及其基板之設計,進一步將該半導體封As the operating frequency of semiconductor wafers increases, the density of components increases, and the operating voltage decreases, the problem of noise generated by semiconductor packages becomes more serious. More specifically, when the components on the semiconductor wafer are switched between on (off) and off (off), the simultaneous switching noise (SSN) generated by the power and ground planes between the substrates will increase. Decrease the benefit of the overall semiconductor package structure, that is, the benefit of the entire system. In order to solve the above-mentioned problem of simultaneous switching noise, the switching noise of the semiconductor package structure must be measured and analyzed to improve the semiconductor package structure and the design of the substrate, and further the semiconductor package

Description of Invention (3). In order to make the above and other objects, features, and advantages of the present invention clearer, the preferred embodiments of the present invention will be described below, and the accompanying drawings will be described in detail below. [Embodiment] Figs. 1-3 show a substrate 100 according to the present invention, which is used to measure a semiconductor package structure while switching noise (Simu 1 taneous Switch Noise; SSN). The substrate loo has a dielectric layer 120, which is made of a dielectric material. A power plane 132 and a ground plane 142 are respectively disposed on the top and bottom surfaces of the dielectric layer 120 of the substrate 100. For example, as shown in the figure, the power supply layer 3 2 is disposed on the bottom surface of the dielectric layer 2 20, and the ground layer 42 is disposed on the top surface of the dielectric layer 2 20. Needless to say, the power supply layer 132 can also be disposed on the top surface of the dielectric layer 120, and the pad layer 142 can also be disposed on the bottom surface of the dielectric layer 120. As shown in FIGS. 2 and 3, a plurality of connection pads 14 and 30 are disposed on the top and bottom surfaces of the dielectric layer 120 of the substrate 100, respectively, and a plurality of conductive vias (V ia ) 1 2 2 Individual interconnections. A solder mask (Solder Mask) 144 is disposed on the top surface of the dielectric layer 120 [partially covering the connection pad 140 and the ground layer 142. The connection 142 has a large area on the body, and the present production-prevention layer 144 disposed on the connection 142 has a pad opening 146 for defining a connection 148. ^ For example, please refer to Figs. 4-6, which show the 591781 according to the present invention. 5. Description of the Invention (4) The substrate 100 measures a ball grid array package structure 2000. The ball grid array package structure 200 has a substrate 210, a colloid 212 disposed on the substrate 210 for encapsulating a semiconductor wafer (not shown), and a plurality of solder balls 220 fixed on the substrate 2 10. . The plurality of solder balls 2220 are electrically connected to the semiconductor wafer. During the measurement, the semiconductor package structure 2 G0 and the solder ball 2 2 0 can be electrically connected and fixed to the connection of the substrate by a known surface mounting technique (Surface Mount Technique). On the pad 148. When the solder ball 2 2 0 a of the ball grid array package structure 2 0 0 needs to be grounded, a conductive adhesive, such as $ glue 230 a, is applied between the ground layer 142 and the connection pad H 0a. The solder ball 220a is electrically connected to the ground layer 142. When the solder ball 2 2 0 b of the ball grid array package structure 200 needs to supply power, a conductive adhesive, such as silver adhesive 230 b, is applied between the power supply layer 132 and the connection pad 1 30 b. The solder ball 22b is electrically connected to the power supply layer 132 via the conductive via 22 and the connection pad 140b. Needless to say, insulation can also be maintained between the pads 130 and 140 and the power supply layer 132 and the ground layer 142, so that the solder ball 220 will not be grounded or supplied with power. As shown in the figure, the pads 48 of the substrate 100 are distributed in an array so as to cooperate with different semiconductor package structures. Furthermore, the connection can be distributed at a fixed or variable pitch to match different package structures. ¥ As mentioned earlier, the solder balls of the semiconductor package structure can be selectively connected (or supplied with power), and the semiconductor package structure can be easily measured for noise.
