    • In a semiconductor device and a method of manufacturing the same, a dummy region which can suppress occurrence of a parasitic capacity can be provided for reducing a difference in level without increasing manufacturing steps in number. A semiconductor substrate is provided at its main surface with an isolation region formed by a trench, and a dummy region leaving the main surface is formed in the isolation region for the purpose of reducing an influence by the difference in level in a later step. The dummy region includes p- and n-type impurity regions each extending a predetermined depth from the surface. Since a pn junction occurs at the bottom of the impurity region, a depletion layer spreads in the pn junction, and thereby reduces a parasitic capacity between the dummy region and a conductive interconnection located in a crossing direction at a higher position. The impurity regions and source/drain regions of p- and n-channel transistors in active regions are simultaneously formed by impurity implantation.
    • 在半导体器件及其制造方法中,可以提供能够抑制寄生电容的发生的虚拟区域,以减少水平差而不增加数量的制造步骤。 半导体衬底在其主表面上设置有由沟槽形成的隔离区域,并且在隔离区域中形成了离开主表面的虚拟区域,以便减少后续步骤中的电平差的影响。 虚拟区域包括各自从表面延伸预定深度的p型和n型杂质区。 由于在杂质区域的底部发生pn结,所以在pn结中扩散耗尽层,从而降低位于较高位置处的交叉方向上的虚设区域和导电配线之间的寄生电容。 有源区中的p沟道晶体管和n沟道晶体管的杂质区和源/漏区同时由杂质注入形成。

    • A lamp reflector for a lamp that conforms to a vehicle body shape and method of producing such reflector, including a die therefor. The lamp reflector comprises a plurality of reflecting sections disposed about an optical axis of the lamp. Significant differences in light distribution at the boundaries between the reflecting sections are avoided by using a fundamental surface K of a reflecting surface 3 that may be generated as a free surface so as to conform to a vehicle body shape. After a reference curve is set on the fundamental surface K, several points P, P, . . . are specified on the reference curve. A very small reflecting surface R is determined at the point P according to the law of reflection so that a ray emitted from a light source and made incident on the point P is reflected to become a ray in parallel with the optical axis. Then, a tangential plane T of the fundamental surface at the point P is determined, and an outer product W of a normal vector N.sub.-- T of the tangential plane T and a normal vector N.sub.13 R of the very small reflecting surface R is calculated. A closed curve is generated by performing vector control in which the outer product W is employed as its tangential vector at each reflection point P around the optical axis, and connecting the tangential vectors by spline approximation.
    • 一种符合车体形状的灯的灯反射器和制造这种反射器的方法,包括一个管芯。 灯反射器包括围绕灯的光轴设置的多个反射部分。 通过使用可以作为自由表面产生的符合车身形状的反射面3的基面K来避免反射部分之间的边界处的光分布的显着差异。 在基面K上设置参考曲线后,可以将几个点P,P, 。 。 在参考曲线上指定。 根据反射定律在点P处确定非常小的反射表面R,使得从光源发射并入射到点P上的光线被反射成与光轴平行的射线。 然后,确定点P处的基面的切线面T,并计算切线面T的法线矢量N-T的外积W和非常小的反射面R的法线向量N13R。 通过执行矢量控制来生成闭合曲线,其中使用外积W作为围绕光轴的每个反射点P处的切向矢量,并且通过样条近似来连接切向矢量。
