Abstract
The utility model relates to a mantle is used in PSS that receives a little preparation, the mantle includes a mantle main part, and this mantle main part is the cuboid form, is provided with broach group in one side of the major axis direction of mantle main part, broach group comprises the broach that a plurality of equidistance side by side distribute jointly, still be provided with high reflective metal layer on the inner wall of two adjacent recesses that the broach formed, and high reflective metal layer's both sides all is provided with a lead angle that extends to the recess lateral wall. The utility model has the advantages of: the utility model provides a high reflective metal layer is add through the inner wall of the recess that the broach formed adjacent to the mantle, is exposing when handling, and light was when advancing the mantle, and part light can block by high reflective metal layer, can form the light zone territory of the being exposed to the sun light zone that does not expose to the sun, need not the mantle and shen ru contacts with gluing, has improved pial life.
Description
Technical field
This utility model relates to chip manufacturing field, particularly to a kind of micro-nano PSS preparation mantle.
Background technology
Light emitting diode (LED) is the advantages such as a kind of electro-optic conversion, energy-efficient, environmental protection, life-span length, refers in traffic
Show, indoor and outdoor total colouring, the aspect such as LCD TV backlight source have a wide range of applications, and especially can realize half with LED
Conductor solid-state illumination, it is expected to become a new generation's light source and enters huge numbers of families, causes the mankind to illuminate the revolution in history, wherein blue precious
Applying yellow fluorescent powder on the blue-ray LED chip of stone lining bottom growth epitaxy of gallium nitride, blue light excitated fluorescent powder sends gold-tinted, blue
Light and gold-tinted are mixed to get white light, thus obtain white light with blue-ray LED.Gallium nitride substrate material is common two kinds, i.e. blue precious
Stone and carborundum, carborundum machining property is poor, and the problem in terms of expensive and patent makes it apply to be limited, because of
This substrate being currently used in GaN epitaxial growth is mainly sapphire, epitaxial layer of gallium nitride and sapphire lattice mismatch phase
When greatly, residualinternal stress is relatively big, so growing gallium nitride easily causes substantial amounts of defect on sapphire, and these defects are significantly
Reduce luminescent device luminous efficiency；There is the difference of bigger refractive index between GaN and air, light shooting angle is less simultaneously,
Significant portion is totally reflected back to LED chip internal, reduces the extraction efficiency of light, increases heat radiation difficulty, affects LED device
The reliability of part.Employing nanoscale PPS substrate technology can be substantially reduced the density of the dislocation of nitride material, relaxes extension raw
The residualinternal stress produced time long, improves internal quantum efficiency, and light extraction efficiency is substantially improved.
During carrying out micro-nano PSS preparation, when being exposed processing, need mantle and glue deep contact, and
Mantle typically uses resin material, glue therefore can be caused to pollute mantle, also reduce the service life of mantle simultaneously,
In order to improve the service life of mantle, now work out the preparation method of a kind of new micro-nano PSS, when being exposed processing, soft
Film only need to micro-with glue contact can realize being exposed unexposed area, region, therefore for the improvement of this technique, needs research one
New mantle.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of micro-nano PSS preparation mantle, it is possible to only realize mantle
Micro-with glue need to contact and can realize being exposed unexposed area, region.
For solving above-mentioned technical problem, the technical solution of the utility model is: a kind of micro-nano PSS preparation mantle, its wound
New point is:
Described mantle includes a mantle main body, and this mantle main body is rectangular-shaped, at the one of the long axis direction of mantle main body
Side is provided with comb group；
Described comb group is collectively formed by some comb being equally spaced side by side, two adjacent comb formed recessed
It is additionally provided with high reflecting metal layer on the inwall of groove, and the both sides of high reflecting metal layer are provided with one and extend to recess sidewall
Lead angle.
The utility model has the advantage of: the mantle in this utility model is by the groove that formed at adjacent comb
Inwall sets up high reflecting metal layer, and when being exposed processing, light was when entering mantle, and part light can be by high reflecting metal layer institute
Stop, can be formed and be exposed unexposed area, region, it is not necessary to mantle deeply contacts with glue, improve the service life of mantle.
Accompanying drawing explanation
With detailed description of the invention, this utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is the schematic diagram of micro-nano PSS preparation mantle of the present utility model.
Fig. 2 is the schematic diagram of the glue after utilizing micro-nano PSS preparation mantle of the present utility model exposure.
Detailed description of the invention
The following examples can make professional and technical personnel that this utility model is more fully understood, but the most therefore will
This utility model is limited among described scope of embodiments.
A kind of micro-nano PSS preparation mantle as shown in Figure 1, including mantle main body 1, comb group and high reflecting metal layer 3.
This mantle main body 1, in rectangular-shaped, is provided with comb group in the side of the long axis direction of mantle main body 1.
Comb group is collectively formed by some comb 2 being equally spaced side by side, at the groove that two adjacent comb 2 are formed
Inwall on be additionally provided with high reflecting metal layer 3, and the both sides of high reflecting metal layer 3 are provided with one and extend to recess sidewall
Lead angle.
Operation principle: when being exposed, as shown by the arrows in Figure 1, light is through mantle, through too high for opticpath
The light of reflective metal layer 3 can be blocked, and the light through comb 2 can pass through arrival Jiao4Chu, thus through exposure-processed
After glue 4 can form exposure area 5 and unexposed area 6, as shown in Figure 2.
Skilled person will appreciate that of the industry, this utility model is not restricted to the described embodiments, above-described embodiment and
Described in description, principle of the present utility model is simply described, on the premise of without departing from this utility model spirit and scope,
This utility model also has various changes and modifications, and these changes and improvements both fall within claimed this utility model scope
In.This utility model claims scope and is defined by appending claims and equivalent thereof.
