Title: Etching method of semiconductor
Inventor: SHIGEMATSU HISAO
IPC: H01L29/737
Filed: 1991-03-20
Abstract: PURPOSE:To etch an InAlAs layer or an InP layer on an InGaAS layer in a high selection ratio by a method wherein a liquid which has mixed hydrochloric acid, phosphoric acid and water in a specific volume ratio is used as an etchant. CONSTITUTION:Whth an InAlAs layer 10 or an InP layer formed on an InGaAs layer 11 is etched selectively, a liquid which has mixed hydrochloric acid, phosphoric acid and water is used as an etchant and their volume ratio is set approximately to HCl: TI3O4:H2O=30:1:20. For example, the whole surface of an InAlAs layer 10 on an InGaAs layer 11 is cleaned by using an o2 asher; after that, an opening is formed only in a face to be etched by using a resist 12; a pretreatment by using an ammonia aqueous solution is performed for 30 seconds in order to prevent the surface from being roughened. After that, the surface is washed immediately by water for one minute; N2 gas is sprayed in order to prevent the InAlAs layer from being oxidized. Then, the material to be etched is put in said etchant (at room temperature) and is etched for one minute while it is moved in a direction perpendicular to the face to be etched.

IPC: B41M5/00
Filed: 1987-03-12
Abstract: PURPOSE:To securely prevent supply of two sheets at a time in supplying the sheet, by subjecting both the surface of an image-receiving layer and the back side of a base sheet to an antistatic treatment to ensure that the surface resistivities of the surface of the image-receiving layer and the back side of the base sheet are set to be respectively not less than specified values. CONSTITUTION:The surface of an image-receiving layer and the back side of a base sheet of a thermal transfer recording sheet are subjected to an antistatic treatment to set the surface resistivity of the surface of the layer to be not more than 1X10<13>OMEGAcm and that of the back side of the base sheet to be not more than 1X10<10>OMEGAcm. To achieve the antistatic treatment, the ratio of the amount of an antistatic agent to the amount of a resin as a binder is suitably controlled. The antistatic agent may be an ionic surface active agent, and may also be a polysiloxane compound. Thus, an excellent antistatic effect can be contrived, and it is possible to securely prevent supply of two sheets at a time, which is liable to occur particularly in supplying the sheet at the time of thermal transfer recording.
