    摘要: After an insulating layer made of BPSG is formed on a diffusion layer, a contact hole is formed to expose the diffusion layer. Then, a first aluminum layer is formed in the contact hole. Then, first and second TEOS layers are formed. Thereafter, a thin film resistor is formed on the second TEOS layer by photo-lithography and etching treatments. In this process, the other parts are covered with the second TEOS layer to prevent being damaged. As a result, occurrence of a leak current at the diffusion layer and the like can be prevented. Further, a third TEOS layer is formed on the thin film resistor, and then a second aluminum layer is formed to be electrically connected to the thin film resistor through a contact hole by an ECR dry etching treatment. In this etching treatment, the thin film resistor is not damaged due to the third TEOS layer.

    摘要: A laser trimming is favorably performed by a strengthened laser beam energy. A level difference portion having a taper portion that is oblique with respect to the thicknesswise direction of a semiconductor substrate is formed at a surface of a semiconductor substrate. An insulating film is formed thereon and has its surface made flat, and then the thin film element is formed thereon. Thereafter, laser trimming is performed with respect to the thin film resistor. As a result, a state of interference between incident laser beam and reflected laser beam reflected from the interface between the semiconductor substrate and the insulating film is varied to thereby enable the production of a zone where laser beam energy is strengthened and a zone where laser beam energy is weakened.

    摘要: A lateral semiconductor device includes a semiconductor layer, an insulating layer, and a resistive field plate. The semiconductor layer includes a first semiconductor region and a second semiconductor region at a surface portion, and the second semiconductor region makes a circuit around the first semiconductor region. The insulating layer is formed on a surface of the semiconductor layer and is disposed between the first and second semiconductor regions. The resistive field plate is formed on a surface of the insulating layer. Between the first and second semiconductor regions, a first section and a second section are adjacent to each other along a circumferential direction around the first semiconductor region. The resistive field plate includes first and second resistive field plate sections respectively formed in the first and second sections, and the first and second resistive field plate sections are separated from each other.
