Abstract
The utility model relates to a to-be-cut silicon bar comprising a crystal bar, bar-sticking glass and a bar-sticking iron plate. The crystal bar, the bar-sticking glass and the bar-sticking iron plate are arranged in sequence from top to bottom and the bar-sticking glass in the middle is of minimum shape. Adhesive tapes are respectively arranged on the arc face of the crystal bar, the side face of the bar-sticking glass and the exposed surface of the bar-sticking iron plate. Before the to-be-cut silicon bar is sent into a multi-wire saw to be cut, the adhesive tapes and bar-sticking glue are torn off to ensure that no bar-sticking glue is attached to the to-be-cut silicon bar so that cutter line marks can be prevented from being generated when silicon chips are cut in a multi-line mode.
Description
Technical field
The utility model relates to a kind of silicon rod to be cut.
Background technology
At present, in the multi-thread production process that cuts into silicon chip of crystal bar, because impurity such as bar glue come off in cutting process; Sneak into reasons such as cutting mortar; Cause the edge of a knife that of silicon chip often to occur stria easily, influenced the silicon chip quality, the percentage of A-class goods of line being cut silicon chip has caused very big influence.
Summary of the invention
The purpose of the utility model provides the silicon rod a kind of to be cut that goes out edge of a knife stria that produces in the time of preventing multiline cut silicon chips.
The technical scheme that the utility model is taked is: a kind of silicon rod to be cut; It comprises crystal bar, sticking excellent glass, sticking excellent iron plate; Crystal bar, sticking excellent glass, sticking excellent iron plate is provided with from top to bottom successively and middle sticking excellent glass is minimum shape, it is characterized in that the side of the arc surface of crystal bar, sticking excellent glass and the table plane of exposing of sticking excellent iron plate are provided with adhesive tape.
Adopt the utility model, before sending into the multi-line cutting machine cutting, adhesive tape is torn together with bar glue, just can guarantee that silicon rod to be cut does not have bar glue, thereby produce edge of a knife stria when having prevented multiline cut silicon chips.
Description of drawings
Fig. 1 is the sketch map of the utility model.
Sequence number is represented among the figure: crystal bar 1, sticking excellent glass 2, sticking excellent iron plate 3 and adhesive tape 4.
The specific embodiment
Embodiment below in conjunction with concrete is described further the utility model.
