一种内嵌式电路的晶体管结构,其包括:
一芯片,该芯片具有多数的电极接点;
至少一金属层,该金属层是以粘着层层迭于上述的芯片上,且该金属层是以导线与电极接点电性连接;
多数导线架,各导线架是分别设置于上述芯片的至少二侧,且各导线架的厚度至少等于芯片的厚度,而各导线架是以导线与金属层电性连接;以及

所述的内嵌式电路的晶体管结构,其中,该金属层是透过以金属导线与芯片的电源电极接点连接而定义为电源面。
所述的内嵌式电路的晶体管结构,其中,该金属层与芯片上的电极接点并无导线做电性连接。
所述的内嵌式电路的晶体管结构,其中,该金属层与导线架并无导线做电性连接。
所述的内嵌式电路的晶体管结构,其中,该导线架是可为ㄈ形的弯折状,供于芯片及金属层的二侧分别夹设一ㄈ形的导线架,并以导线电性连接芯片与导线架,而可供堆栈或并接另一所需的晶体管。
