## Abstract

A method for manufacturing a light emitting device package includes: preparing a base frame including an annular base part, at least a pair of lead parts extending to an inner side of the base part, and at least one support part extending to the inner side of the base part in a direction different from that of the lead parts and having a step structure formed on at least one surface of an end thereof; forming a package main body such that the package main body is combined to the step structure of the support part; separating the lead parts from the base part; disposing a light emitting device on at least one of the lead parts; and separating the package main body from the support part.

## Claims

### Claim 1

A method for manufacturing a light emitting device package, the method comprising:
preparing a base frame including an annular base part, at least a pair of lead parts extending to an inner side of the base part, and at least one support part extending to the inner side of the base part in a direction different from that of the lead parts and having a step structure formed on at least one surface of an end thereof;
forming a package main body such that the package main body is combined with the step structure of the support part;
separating the lead parts from the base part;
disposing a light emitting device on at least one of the lead parts; and
separating the package main body from the support part.

### Claim 2 (depends on 1)

The method of claim 1, wherein the step structure has a configuration in which an upper area or a central area of one surface of the end of the base part is protruded as compared with other areas thereof.

### Claim 3 (depends on 1)

The method of claim 1, wherein the package main body is formed to be combined with the pair of lead parts.

### Claim 4 (depends on 3)

The method of claim 3, wherein the package main body is formed to fill the space between the pair of lead parts.

### Claim 5 (depends on 1)

The method of claim 1, wherein the package main body has a recess structure in which a portion of the side thereof is depressed due to the step structure.

### Claim 6 (depends on 1)

The method of claim 1, wherein the package main body is formed to have at least a portion of a lower surface of the lead part exposed.

### Claim 7 (depends on 6)

The method of claim 6, wherein a lower surface of the package main body is coplanar with a lower surface of at least one of the pair of lead parts and the support part.

### Claim 8 (depends on 1)

The method of claim 1, wherein, in the separating of the package main body from the support part, the step structure combined with the package main body is removed from the package main body.

### Claim 9 (depends on 1)

The method of claim 1, wherein, in the separating of the package main body from the support part, the support part is cut to separate the step structure from the other remaining portions of the support part.

### Claim 10 (depends on 9)

The method of claim 9, wherein one side of the package main body and one side of the step structure are coplanar.

### Claim 11 (depends on 1)

The method of claim 1, wherein the disposing of the light emitting device on at least one of the lead parts is performed after the lead parts are separated from the base part.

### Claim 12 (depends on 1)

The method of claim 1, wherein the disposing of the light emitting device on at least one of the lead parts is performed before the lead parts are separated from the base part.

### Claim 13 (depends on 1)

The method of claim 1, wherein a plurality of base parts are provided, and the plurality of base parts are integrally formed in columns and rows.
