Abstract
The utility model discloses a basal plate for image sensing chip encapsulation. In order to provide a component for encapsulating the semiconductor which can reduce the volume of the image sensor, improve the quality of the image sensor and reduce the manufacturing cost of the image sensor, the utility model is designed, which comprises a plurality of metal sheets arrayed symmetrically and an adhesive body. The a plurality of metal sheets arrayed symmetrically are provided with first and second plates with different heights and a third plate for connecting the first and second plate, thus the middle of the metal sheets arrayed symmetrically forms a groove for placing the image sensing chip; the adhesive body covers fixedly a plurality of symmetrical metal sheets so as to form upper and lower surfaces, which makes the upper surface of the adhesive body exposed on top of the first and second plates of a plurality of metal sheets.
Description
Technical field
The utility model belongs to the parts of encapsulated semiconductor, particularly a kind of substrate that is used for the image sensing wafer encapsulation.
Background technology
As shown in Figure 1, the applicant comprises sheet metal 10, flange layer 16 and the photic zone 22 that arrange several spaces in the image sensor of 91/03/27 No. 091203873 patent application that proposes.
Sheet metal 10 forms first plate 12 and second plate 14 of differing heights.
Flange layer 16 is periphery and the bottom surface that is formed at several sheet metals 10, and top and the following of second plate 14 of first plate 12 of sheet metal 10 exposed by flange layer 16, and forms disposal area 20 in order to ccontaining image sensing wafer 18 with number sheet metals 10.
Photic zone 22 is to be covered on flange layer 16 tops, in order to cover image sensing wafer 18, makes image sensing wafer 18 can see through photic zone 22 and receives the light signal.
Only, though aforesaid image sensor can reach the effect and the purpose of its creation.So, the highly quite high flange layer 16 of essential formation in its whole knot with so that photic zone 22 is provided with thereon, can cover image sensing wafer 18.So, it can't reach compact demand.And first plate, 12 junctions of flange layer 16 and sheet metal 10 near the right angle state, more easily keep impurity (particle), not only cause being difficult for of cleaning on the processing procedure, and easily have influence on the quality of image sensor.
Summary of the invention
The purpose of this utility model provides a kind of substrate that is used for the image sensing wafer encapsulation that reduces image sensor volume, raising image sensor quality, reduces the image sensor production cost.
The utility model comprises sheet metal and the adhesive body that several are arranged symmetrically; The 3rd plate that several sheet metals of arranging symmetrically are provided with first and second plate of differing heights and connect first and second plate makes several sheet metals of arranging mutually form the groove that image sensing wafer is set in central part; Adhesive body is coated and fixed several symmetrical sheet metals and forms upper and lower surface, and the top upper surface by adhesive body of first and second plate of several sheet metals is exposed.
Wherein:
Several sheet metals of arranging mutually are provided with the intermediate plate that image sensing wafer can be set in the groove that central part forms.
The intermediate plate bottom surface is exposed by the adhesive body lower surface.
The following of several sheet metal second plates exposed by the adhesive body lower surface.
The sealing system is several symmetrical sheet metals that are coated and fixed with industrial plastic material ejection formation.
Second plate of the sheet metal that is exposed by the upper surface of adhesive body is electrically connected image sensing wafer by several wires.
Because the utility model comprises sheet metal and adhesive body that several are arranged symmetrically; The 3rd plate that several sheet metals of arranging symmetrically are provided with first and second plate of differing heights and connect first and second plate makes several sheet metals of arranging mutually form the groove that image sensing wafer is set in central part; Adhesive body is coated and fixed several symmetrical sheet metals and forms upper and lower surface, and the top upper surface by adhesive body of first and second plate of several sheet metals is exposed.Because sheet metal forms the groove that image sensing wafer is set, during encapsulation, image sensing wafer can be arranged in the groove, photic zone then is arranged on first plate of sheet metal, so because of needn't on adhesive body, forming the height that flange layer can reduce the overall package body in addition, to reach compact purpose; The 3rd plate of first and second plate of connection of sheet metal is skewed, can reduce the residual of impurity and be convenient to and remove, and improves its process quality.Not only reduce the image sensor volume, and improve image sensor quality, reduction image sensor production cost, thereby reach the purpose of this utility model.
