This paper describes the design and fabrication of an integrated circuit which controls the phase of VTR servo systems. The integrated circuit was designed using 6#m design rule and its chip size is 3.6$ imes$3.55mm$^2$. On the other hand it was fabricated using SBC, analog-compatible 12 L and double layer metal fabrication process technology. As a result, we succeeded in fabrication of If which satisfied D. C. characteristics and phase control function.
