Currently, optic communication mainly applies INP substrate slice to carry out epitaxial growth and rear end processing with semiconductor laser, in the processing of rear end
BAR end face optical coating technique is to guarantee the critical process of laser parameter.
BAR optical coating exactly plates corresponding optical medium film layer at the both ends of BAR item, coating process in order to
Guarantee that coating quality, BAR item cannot continuously be put, one folded up between BAR item and accompanies item, accompany the width ratio BAR item of item slightly narrow,
It can make BAR slightly protruding when putting.Existing method is to put BAR item on one block of sheet glass and accompany item, can only be protected in this way
There is a protrusion in card upper end, lower end with accompany item concordant, the lower end of BAR item is directly contacted with sheet glass, be easy to appear when putting breakage with
It is dirty, and that end that do not protrude is easy for film layer occur in plated film being adhered phenomenon, just will appear film in the separation of BAR item
The damaged situation of layer, yields reduce, how to guarantee the integrality of the optical medium film layer of vallum when BAR item is put, become and grind
The emphasis and difficult point studied carefully.
Presently, there are the problem of have: 1. when BAR item is put, and one can be folded up between BAR item accompanies item, accompany after plated film
Item can not reuse, and cause to waste, at high cost；2. accompanying the end face of item if any breakage, the optical medium at BAR both ends is easily caused
Film layer is imperfect, influences quality；3.BAR item puts that quantity is few, and optical coating production capacity is lower.
Therefore, it devises one kind and can not only improve and put quantity, and in the case where item is accompanied in cancellation, moreover it is possible to possess both ends
BAR structure of the integrality of the optical dielectric matter of vallum solves the above problems.
Summary of the invention
To overcome the deficiencies in the prior art described above, it is an object of that present invention to provide a kind of can be improved to put the BAR of quantity

The both ends in vallum area, the vallum area extend respectively to the edges at two ends of the chip structure；The chip knot of vallum area two sides
First metal area is equipped on structure, two first metal areas are symmetrical arranged about the vallum area, first metal area
Side is provided with the second metal area, and two second metal areas are symmetrically arranged at the two sides in the vallum area；First metal
The height of area and second metal area is all larger than the height in the vallum area.
Preferred technical solution are as follows: the vallum area includes the vallum of middle part protrusion and the groove of two sides, the vallum area
Upper layer be provided with metal layer.
Preferred technical solution are as follows: the shape of first metal area and second metal area is square.
Preferred technical solution are as follows: the area of first metal area is greater than the area of second metal area.
Preferred technical solution are as follows: the thickness of first metal area and second metal area is not less than the vallum
Twice of area's metal layer thickness.
Preferred technical solution are as follows: the distance of first metal area to the vallum area is greater than second metal area and arrives
The distance in the vallum area.
Since above-mentioned technical proposal is used, the present invention has the advantage, that compared with prior art
The configuration of the present invention is simple, processing cost is low, and practicability is high, is not required to change operation process, is also not required to additional investment equipment, can
With the quantity put when BAR optical coating of simple and convenient reliable raising, the use for accompanying item can also be cancelled, solve plated film
The problem of production capacity deficiency, it is thus also avoided that the problem of vallum film layer will be peeled off at lower substantially increases yields and production efficiency.
