摘要 | PURPOSE:To form a platinum stripe electrode to enable continuous oscillation at a high temperature, and to enhance the characteristic of an element by a method wherein after a part of a dierectric film is removed in a stripe type to expose the surface of a semiconductor, platinum is evaporated on the whole surface, alloying treatment is performed, and then a platinum layer on the dielectric film is removed. CONSTITUTION:A clad layer 6, an active layer 5, a clad layer 4 and a cap layer 3 are grown in order on a substrate 7, an SiO2 oxide film is laminated thereon, and photolithography is performed using a mask to form stripe type grooves. The wafer and ZnP2, ZnAs2, InP are put in a quartz ampoule to be sealed in a vacuum, Zn is diffused up to the middle of the p-type clad layer 4, and the SiO2 film is removed. An SiO2 film is adhered again, stripe type grooves of two pieces are formed performing positioning of a mask, and mesa etching is performed using a Br2-CH3OH solution. Then an SiO2 film 10 is adhered again, positioning of a mask is performed, and stripes are formed. Pt is evaporated thereon, and after alloying is performed, the platinum layer on the dielectric film is removed. |
其他摘要 | 目的:形成铂条形电极,使其能够在高温下连续振荡,并通过一种方法增强元件的特性,其中在以条纹类型去除一部分的称重膜以暴露半导体表面之后,在整个表面上蒸发铂,进行合金化处理,然后除去介电膜上的铂层。组成:在基板7上依次生长包层6,有源层5,包层4和盖层3,在其上层叠SiO2氧化膜,并使用掩模进行光刻以形成条纹型槽。将晶片和ZnP2,ZnAs2,InP放入石英安瓿中以在真空中密封,Zn扩散到p型覆层4的中间,并除去SiO2膜。再次粘附SiO 2膜,形成两片的条形沟槽,进行掩模的定位,并使用Br 2 -CH 3 OH溶液进行台面蚀刻。然后再次粘附SiO 2膜10,进行掩模的定位,并形成条纹。在其上蒸发Pt,并且在进行合金化之后,去除介电膜上的铂层。 |
