An integrated circuit includes first and second diodes that are electrically connected to a conductive line in antiparallel, to dissipate both positive and negative charges on the conductive line during plasma processing. The size of the contact hole formed over the first impurity area is relatively larger than that of the contact hole formed over the second impurity area. A bandage that can be applied to a bleeding wound to promote the clotting of blood includes a flexible substrate and a gauze substrate mounted thereon. The relationship of the frontrear wheel speed ratio to the steering angle is represented by a curve which is concave in a direction of an axis of increasing speed ratio.
