    • After accumulating a BPSG film layer on a silicon substrate, a first Al--Si--Cu film layer, a W film layer and a second Al--Si--Cu film layer are successively accumulated on this BPSG film layer. A resist pattern with wide-width and narrow-width pattern portions is formed on the second Al--Si--Cu film layer. The wide-width pattern portion is provided at a position corresponding to a contact for connecting a first-layer metallic wiring and a second-layer metallic wiring, while the narrow-width pattern portion is provided at a position corresponding to a wiring portion for the first-layer metallic wiring. After applying first etching on the second Al--Si--Cu film layer with a mask of the resist patter, second etching is applied on the W film layer. Thereafter, by applying third etching, the resist pattern remaining on the first-layer metallic wiring is removed and the first Al--Si--Cu film layer is transfigured into a tall metallic film portion and a short metallic film portion. After accumulating an inter-layer insulating film layer on the first Al--Si--Cu film layer, etchback is applied on this inter-layer insulating film layer until the top of the tall metallic film portion is bared. Then, the second-layer metallic wiring is formed on the inter-layer insulating film layer so that the second-layer metallic wiring is connected with the tall metallic film portion.
    • 在硅衬底上积累BPSG膜层之后,第一Al-Si-Cu膜层,W膜层和第二Al-Si-Cu膜层依次堆积在该BPSG膜层上。 在第二Al-Si-Cu膜层上形成具有宽幅和窄宽图案部分的抗蚀剂图案。 宽幅图形部分设置在与用于连接第一层金属布线和第二层金属布线的接触件相对应的位置处,而窄宽图案部分设置在与布线部分相对应的位置处 第一层金属布线。 在具有抗蚀剂图案的掩模的第二Al-Si-Cu膜层上施加第一蚀刻之后,在W膜层上施加第二蚀刻。 此后,通过施加第三蚀刻,去除残留在第一层金属布线上的抗蚀剂图案,并将第一Al-Si-Cu膜层变形为高金属膜部分和短金属膜部分。 在第一Al-Si-Cu膜层上积累层间绝缘膜层之后,在该层间绝缘膜层上施加回蚀,直到高金属膜部分的顶部露出。 然后,在层间绝缘膜层上形成第二层金属布线,使得第二层金属布线与高金属膜部分连接。

    • It is an object to provide a semiconductor device having a buried multilayer wiring structure in which generation of a resolution defect of a resist pattern is suppressed and generation of a defective wiring caused by the resolution defect is reduced. After a via hole (7) reaching an etching stopper film (4) is formed, annealing is carried out at 300 to 400° C. with the via hole (7) opened. As an annealing method, it is possible to use both a method using a hot plate and a method using a heat treating furnace. In order to suppress an influence on a lower wiring (20) which has been manufactured, heating is carried out for a short time of approximately 5 to 10 minutes by using the hot plate. Consequently, a by-product staying in an interface of an upper protective film (6) and an interlayer dielectric film (5) having a low dielectric constant and a by-product staying in an interface of the etching stopper film (4) and the interlayer dielectric film (5) having a low dielectric constant are discharged so that an amount of the residual by-product can be decreased.

    • A ridge stripe semiconductor laser device includes a first conductivity type cladding layer 103, an active layer 104, a second conductivity type first cladding layer 105, a second conductivity type second cladding layer 108 in a ridge-shaped stripe for confining light in a horizontal transverse direction, and a current blocking layer 107 formed in a region except for at least a part on a ridge that are disposed on a semiconductor substrate 102. In a cross-section perpendicular to a stripe direction of the ridge, each of both lateral surfaces of the ridge includes a first surface 118 that is substantially perpendicular to a surface of the semiconductor substrate and extends downward from an upper end of the ridge, and a second surface 119 that is formed of a substantially linear skirt portion inclined surface that is inclined obliquely downward to an outside of the ridge in a skirt portion of the ridge. The first surface and the second surface are connected directly, or connected via a third intermediate surface. A (111) plane of a semiconductor constituting the second cladding layer is exposed to the second surface. The present invention provides a high power semiconductor laser device with a high kink level and a low operating current.
