Abstract

The invention discloses a compound semiconductor wafer scribing machine, and the wafer scribing machine comprises an equipment shell; a display screen is arranged at the front end of the equipment shell, an operation screen is arranged on one side of the display screen, an adjusting opening is formed in the lower end of the display screen, an observation window is formed in the lower end of the adjusting opening, and a console is arranged on one side of the observation window; the electrical control device comprises a quartz workbench, a first motion control device, a tool bit device, a visualpositioning device, a second motion control device and a gram weight feedback device. According to the compound semiconductor wafer scribing machine, the blank in the aspect of domestic compound semiconductor material scribing is filled up, wafer scribing is conducted on compound semiconductor materials such as gallium arsenide through the diamond scribing tool, accurate alignment can be achievedthrough manual or automatic control, load scribing is set, the damage to compound semiconductor materials is small, and the physical or photoelectric characteristics of the chip are prevented from being damaged.

Description

technical field [0001] The invention relates to the field of chip processing equipment, in particular to a compound semiconductor wafer dicing machine. Background technique [0002] At present, gallium arsenide (GaAs) material is the most produced and widely used compound semiconductor material. Due to its excellent performance and energy band structure, gallium arsenide optoelectronic chips are the main components in the fields of data communication and laser. Compared with traditional silicon semiconductor materials, it mainly has the following characteristics: it can process photoelectric data on one chip at the same time, it has the characteristics of high electron mobility, large band gap, direct band gap, and low power consumption. At present, the advanced production technology of gallium arsenide materials is mainly in the hands of developed economies such as Japan, Germany and the United States. The market is full of compound semiconductor dicing machines produced b...
