## Abstract

The invention discloses a glass carrier having a protection structure, comprising a glass body and a protection layer. The glass body has a top surface, a bottom surface, and a lateral surface. The protection layer covers the lateral surface of the glass body. The protection layer is a hard material with a stiffness coefficient higher than a stiffness coefficient of the glass body. The invention further discloses a manufacturing method of a glass carrier having a protection structure, comprising the following steps: covering the protection layer around the lateral surface of the glass body, wherein the protection layer is the hard material with the stiffness coefficient higher than the stiffness coefficient of the glass body.

## Claims

### Claim 1

A glass carrier having a dual lateral surface protection structure, comprising:
a glass body, having a carrying surface, a bottom surface, and a lateral surface; wherein the carrying surface and the bottom surface are opposite, and the lateral surface connects the carrying surface and the bottom surface;
a first protection layer, fully covering the lateral surface of the glass body; and
a second protection layer, covering the first protection layer over the lateral surface of the glass body;
a circuit board structure, mounted on the carrying surface of the glass body; and
a protection shell, mounted over the circuit board structure and the glass body and exposing the dual lateral surface protection structure of the glass body;
wherein the first protection layer is a hard material with a stiffness coefficient higher than a stiffness coefficient of the glass body and the second protection layer is a soft material with a stiffness coefficient lower than the stiffness coefficient of the glass body;
wherein the first protection layer and the second protection layer are contactless with the circuit board structure.

### Claim 2 (depends on 1)

The glass carrier having the dual lateral surface protection structure as claimed in claim 1, wherein:
the glass body is cuboid, and the first protection layer covers the lateral surface, a part of the carrying surface, and a part of the bottom surface of the glass body.

### Claim 4 (depends on 1)

The glass carrier having the dual lateral surface protection structure as claimed in claim 1, wherein:
the lateral surface of the glass body is arced;
the first protection layer is arced and covers the lateral surface;
the second protection layer is arced.

### Claim 5 (depends on 1)
