Abstract
The utility model relates to a tool for manufacturing semiconductor elements, in particular to a crystal grain screening plate which can be used to install Bi2Te3 accurately. The crystal grain screening plate is composed of a motherboard and a sub-plate, the motherboard is provided with holes which are arranged vertically and transversely in a regular mode, and the sub-plate is provided with the holes which are arranged separately corresponding to the motherboard. Since the structure is adopted, the crystal grain screening plate can be used to place N ends and P ends with interlaced Bi2Te3 rapidly and has the advantages that the speed is high and the crystal grain screening plate can not make mistakes easily.
Description
Technical field
The utility model relates to a kind of instrument of making semiconductor components and devices, specifically relates to a kind of Bi to be installed accurately
2Te
3Crystal grain screening plate.
Background technology
It is proper alignment and weld Bi in length and breadth on porcelain plate that a kind of semiconductor components and devices is arranged
2Te
3Crystal column, such crystal column divide N end and P end, and the arrangement of crystal column on porcelain plate be that N end and P end are staggered with the porcelain plate contact-making surface, are referred to as to interlock and weld; At present, in this operation process, utilization be that band has and arranges motherboard with holes in length and breadth, put requirement according to N end and P end, put at the interval, utilize such motherboard have efficient low, put the shortcoming of makeing mistakes easily.
Summary of the invention
The purpose of this utility model is exactly the problem at above-mentioned existence, the crystal grain screening plate that provides a kind of crystal column to interlock the welding efficiency height, be not easy to make mistakes.
The crystal grain screening plate that is achieved in that of the present utility model is made up of motherboard and daughter board, and motherboard has the hole of proper alignment in length and breadth, and daughter board has the hole of arranging with the motherboard corresponding intervals.
The beneficial effects of the utility model are: owing to taked above structure, make such crystal grain screening plate can put Bi fast
2Te
3Staggered N end and P end have the speed height, the advantage that is difficult for makeing mistakes.
Description of drawings
Fig. 1 is the structural representation of the utility model crystal grain screening plate motherboard
Fig. 2 is the structural representation of the utility model crystal grain screening plank plate
Wherein, 1, motherboard 2, daughter board 3, hole
Embodiment
The utility model will be further described below in conjunction with accompanying drawing.
Crystal grain screening plate forms 2 by motherboard 1 and daughter board, and motherboard 1 has the hole of proper alignment in length and breadth, as shown in Figure 1; Daughter board 2 has the hole of arranging with the motherboard corresponding intervals, as shown in Figure 2; During use, at first daughter board 2 is placed on the motherboard 1, can select the granule shape Bi of N shape or P shape on demand
2Te
3Be spread on the daughter board, vibrations make in the hole 3 of its whereabouts and daughter board 1, and daughter board 2 its double-edged fine-toothed comb effects at this moment can make Bi
2Te
3Be spaced, because motherboard 2 has empty hole 3 at interval, can fill another kind of Bi afterwards
2Te
3, can reach spaced effect, all the other technology are identical with prior art, realize easily.
Claims (1)
1, crystal grain screening plate, it is characterized in that: form (2) by motherboard (1) and daughter board, motherboard (1) has the hole of proper alignment (3) in length and breadth, and daughter board (2) has the hole (3) of arranging with motherboard (1) corresponding intervals.
