    • A semiconductor IC including a resistance element on a circuit substrate. The resistance element includes a resistance layer formed on an insulating layer. The resistance layer is formed using a Si layer obtained by forming an a-Si layer, doping the a-Si layer with impurities, and heating the doped a-Si layer to diffuse the impurities while substantially preserving the fineness of the a-Si layer surface. Preferably, a SiN layer is provided lying beneath the resistance layer. A capacitor may be integrated on the same circuit substrate where the resistance element is formed. In this case, a lower electrode, a SiN dielectric layer, and an upper electrode are formed in this order to constitute a capacitor. The SiN dielectric layer of the capacitor is formed extending from a capacitor formation region to another region, so that the resistance layer of the resistance element is formed on the extending SiN dielectric layer. The lower and upper electrodes of the capacitor may be formed using an a-Si layer, similar to the resistance layer.

    • A lead electrode (57) is formed to expose an active base region (61). On the lead electrode (57) is formed a lead electrode (64) for an emitter electrode via an insulation film (56). When a base contact hole (65') for exposing the lead electrode (57) and an emitter contact hole for exposing the lead electrode (64) are formed at the same time, total thickness of the insulation film on the lead electrode (64) is thinner than that of the insulation layer on the lead electrode (57), which results in excessive etching on a part of the surface of the lead electrode to form recess. The lead electrode (64) is led out to a LOCOS film to form the emitter contact hole in a region on the LOCOS film to expose the lead electrode (64). Therefore, the recess having been formed on the lead electrode (64) upon forming the emitter contact hole is made to form on the LOCOS film outside the emitter region. The recess prevents depth of the emitter region from dispersing.
    • 形成引线电极(57)以暴露活性碱性区域(61)。 在引线电极(57)上经由绝缘膜(56)形成用于发射电极的引线电极(64)。 当同时形成用于使引线电极(57)露出的基极接触孔(65')和用于使引线电极(64)露出的发射极接触孔时,引线电极(64)上的绝缘膜的总厚度 比引线电极(57)上的绝缘层薄,这导致对引线电极的一部分表面的过度蚀刻以形成凹陷。 引线电极(64)被引出到LOCOS膜,以在LOCOS膜上的区域中形成发射极接触孔,以露出引线电极(64)。 因此,在形成发射极接触孔的引线电极(64)上形成的凹部被形成在发射极区域外部的LOCOS膜上。 该凹口防止发射极区域的深度分散。

    • A motor controlling device for mounting on a vehicle, which includes a controller capable of controlling a DC brushless motor at high response and high accuracy. The motor controlling device for mounting on the vehicle to drive the DC brushless motor comprises a main control section (120) for calculating a torque command for the motor, and a current control calculation section (140) constituted by a module or a dedicated LSI independent of the main control section (120). The current control calculation section (140) converts the coordinates of a current of the DC brushless motor into a d-axis direction, i.e., a direction of magnetic flux of a motor rotor, and into a q-axis direction orthogonal to the d-axis direction, and feedback-controls a current in the d-axis direction and a current in the q-axis direction separately.
