Abstract: PURPOSE:To enable a semiconductor device to be highly integrated by a method wherein respective gate regions of a plurality of JFETs are disposed in a array in the perpendicular direction with one another while a source region and a drain region are arranged on both upper and lower sides of the gate regions. CONSTITUTION:A plurality of JFETs 401, 402... are junctioned with one another in series by disposing the respective gate regions 411, 412... in an array in the perpendicular direction to a substrate 42. A source region 43 and a drain region 44 are arranged on upper and lower both sides of the gate regions 411, 412. During the manufacturing process, the gate regions 411, 412... of one JFET are formed in the substrate 42 immediately below a mask 45 by ion-implantation using the mask 45 provided with an opening 45a and simultaneously the source region 43 is formed in the substrate 42 immediately below the opening 45a. Through these procedures, a smaller space suffices compared with that disposed in an array in the lateral direction, thus enabling the semiconductor to be highly integrated.

Abstract: PROBLEM TO BE SOLVED: To easily form input/output terminals other than a ground terminal electrode on a substrate side face and to easily perform realization at a low cost by providing a ground conductor layer formed in a loop shape inside a laminated body so as to surround a passive element. SOLUTION: The ground conductor layer 2a of a lowest layer is formed over the entire upper surface excluding the corner part of a first dielectric layer 1a. On second-forth dielectric layers 1b-1d, the ground conductor layers 2b-2d are formed in the loop shape excluding the corner part. Thus, since a resonator L2 is surrounded by the ground conductor layers 2b-2d formed in the loop shape around it, a shield effect is improved and miniaturization, high stability and a high C/N are secured. Also, since the loop-shaped ground conductor layers 2b-2d are simultaneously formed with an internal conductor by the film formation technique of a normal sheet method or the like, execution is easily performed at a low cost by utilizing a conventional device without newly providing a special process.
