摘要 | PURPOSE:To prevent the separation of a wiring of semiconductor device by a method wherein a binder of thin film of Ti, Cr, etc., having favorable adhesion is provided between a barrier metal of Mo, etc., and the metal wiring. CONSTITUTION:An N type GaAlAs clad layer 6, an N type GaAlAs active layer 7, a P type GaAlAs clad layer 8, and an N type GaAs layers 9 are formed on an N type GaAs substrate 1 according to the liquid phase growth method, a mask 10 having a slender opening of 2mum width is provided on the layer 9, and Zn is diffused to form a P type layer 1 Then an ohmically connecting layer 12 of Ti or Cr, an Mo barrier metal layer 4, and a binder layer 13 of Ti or Cr are evaporated in order, and an electrode wiring layer 4 of Au or Ag is adhered. After thickness of the substrate 1 is regulated to about 100mum, an AuGe layer 14, an Ni layer 15 are evaporated, a binder layer 13 of Ti or Cr is accumulated, and an electrode 5 of Au or Ag is adhered to complete. By this constitution, the separation of the electrode wiring can be prevented. |
其他摘要 | 用途:为了防止半导体器件的布线分离,其中在Mo的阻挡金属等与金属布线之间提供具有良好粘附性的Ti,Cr等薄膜粘合剂。组成:根据液相在N +型GaAs衬底1上形成N型GaAlAs包层6,N型GaAlAs有源层7,P型GaAlAs包层8和N型GaAs层9在生长方法中,在层9上设置具有2μm宽的细长开口的掩模10,并且使Zn扩散以形成P +型层1然后,形成Ti或Cr的欧姆连接层12,Mo阻挡金属在第4层中,依次蒸发Ti或Cr的粘合剂层13,并粘附Au或Ag的电极配线层4。在将衬底1的厚度调节到约100μm之后,蒸发AuGe层14,Ni层15,累积Ti或Cr的粘合剂层13,并完成Au或Ag的电极5的粘合。通过这种结构,可以防止电极布线的分离。 |
