Description

Manipulator
Technical field
The utility model relates to the semiconductor-fabricating device technical field, relates in particular to a kind of manipulator.
Background technology
In semiconductor fabrication, photoetching process is in the status at center, is most important processing step during integrated circuit is produced.The making of semiconductor chip is divided into multilayer usually, and the making of each layer all needs to carry out figure and limit, forming ad hoc structure, as, form contact hole or metal connecting line etc.The figure of these ad hoc structures limits normally and is realized by photoetching process, and photoetching is one and utilizes lay photoetching mask plate that the structure graph of design is transferred to technical process on the wafer.
Before chip manufacturing, the layout of first device according to each layer on the chip, metal wire, connection etc. designs and produces one or more lay photoetching mask plates, then, utilizes photoetching process that the figure on this lay photoetching mask plate is transferred on the wafer again.
Lay photoetching mask plate (reticle), be also referred to as mask or light shield, it is a kind of flat board that has light transmission for exposure light, has at least one geometric figure that exposure light is had light-proofness on it, can realize blocking selectively the light that shines on the wafer surface photoresist, and finally on the photoresist of wafer surface, form corresponding pattern.The quality of mask is the quality of the formed photoresist pattern of influence directly, and defective on it or pollutant may cause the defective that repeats in each semiconductor devices that forms on entire wafer.As, on mask, there is certain defective, make should printing opacity the zone when existing a points of contamination light tight, photoresist pattern on the wafer and not conforming to of designing in advance may cause open circuit or short circuit in the formed semiconductor devices in subsequent treatment, cause the performance and the decrease in yield of product, therefore, quality to mask tends to propose very high requirement, ideally, wishes to obtain flawless mask.
In order to guarantee the quality of mask, usually after making, mask to utilize testing tool that it is detected, for example, whether have particle (particle) on the mask in order to detect, the detection board that is called Zaris that uses Brooks (Brooks) company to produce usually carries out procuratorial work to the surface of mask.Simultaneously, in order to prevent that mask is polluted, mask transmits by manipulator usually.In the process of mask being carried out the surface particles detection, mask is delivered to Zaris detection board by manipulator and detects.

Yet because the type of existing mechanical hand five degree of freedom manipulator normally, therefore its control model more complicated produces position of manipulator skew and collision through regular meeting; And owing to directly fixedly connected between the mechanical arm of existing mechanical hand and the mechanical finger, it is rigid connection, therefore, when collision takes place, reduce or absorbing forces of impact without any buffer gear, thereby very likely can damage manipulator and mask, cause heavy losses because of collision.
Therefore, be necessary the existing mechanical hand is improved.
The utility model content
The purpose of this utility model is to provide a kind of manipulator, is rigid the connection with between the mechanical arm that solves the existing mechanical hand and the mechanical finger, easily the problem that causes manipulator and mask to damage because of collision.
For addressing the above problem, the utility model proposes a kind of manipulator, described manipulator comprises mechanical arm and mechanical finger, also comprises elastic connecting device, described elastic connecting device connects described mechanical arm and described mechanical finger.
Optionally, described elastic connecting device comprises top plate, intermediate plate and lower plywood from top to bottom, and an end of described top plate links to each other with described mechanical finger, and the bottom of described top plate has a plurality of equally distributed pins; End away from described mechanical finger of described intermediate plate links to each other with described mechanical arm, has a plurality of through holes on the described intermediate plate equably, and has on the described intermediate plate that a plurality of and described pin is complementary and corresponding V-type groove; Link to each other the described through hole of described elastomeric element break-through by a plurality of elastomeric elements between described top plate and the described lower plywood.
Optionally, the quantity of described pin and described V-type groove is 3.
Optionally, the quantity of described through hole and described elastomeric element is 4.
Compared with prior art, the manipulator that the utility model provides comprises mechanical arm and mechanical finger, also comprises elastic connecting device, and described elastic connecting device connects described mechanical arm and described mechanical finger; Thereby when described mechanical finger is subjected to the external force collision, described impact force will be born by described elastic connecting device, thereby reduce the collision degree to mechanical finger and mask, help protecting described manipulator and mask not to be damaged.
Description of drawings
Fig. 1 is the front view of existing mechanical hand;
The front view of the manipulator that Fig. 2 provides for the utility model embodiment;
The manipulator that Fig. 3 provides for the utility model embodiment is in use by the schematic diagram after the collision.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the manipulator that the utility model proposes is described in further detail.According to the following describes and claims, advantage of the present utility model and feature will be clearer.It should be noted that accompanying drawing all adopts very the form of simplifying and all uses non-ratio accurately, only be used for conveniently, the purpose of aid illustration the utility model embodiment lucidly.
Core concept of the present utility model is, a kind of manipulator is provided, and described manipulator comprises mechanical arm and mechanical finger, also comprises elastic connecting device, and described elastic connecting device connects described mechanical arm and described mechanical finger; Thereby when described mechanical finger is subjected to the external force collision, described impact force will be born by described elastic connecting device, thereby reduce the collision degree to mechanical finger and mask, help protecting described manipulator and mask not to be damaged.
Please refer to Fig. 2, the front view of the manipulator that Fig. 2 provides for the utility model embodiment, as shown in Figure 2, the kind manipulator that the utility model embodiment provides comprises mechanical arm 201 and mechanical finger 202, also comprise elastic connecting device, described elastic connecting device connects described mechanical arm 201 and described mechanical finger 202.Wherein, described mechanical finger 202 carrying masks 300.
Further, described elastic connecting device comprises top plate 410, intermediate plate 420 and lower plywood 430 from top to bottom, one end of described top plate 410 links to each other with described mechanical finger 202, and the bottom of described top plate 410 has a plurality of equally distributed pins 411 (only illustrating two among the figure); End away from described mechanical finger 202 of described intermediate plate 420 links to each other with described mechanical arm 201, have a plurality of through holes 421 (only illustrating two among the figure) on the described intermediate plate 420 equably, and have the V-type groove 422 (only illustrating two among the figure) that a plurality of and described pin 411 is complementary on the described intermediate plate 420, described pin 411 inserts in the described V-type groove 422; Link to each other the described through hole 421 of described elastomeric element 440 break-through by a plurality of elastomeric elements 440 (only illustrating two among the figure) between described top plate 410 and the described lower plywood 430.
