## Abstract

A substrate container with enhanced flow field therein includes a box, at least one offset inflation mechanism and at least one gas diffusion mechanism. The offset inflation mechanism is disposed outside internal receiving space of the box. The offset inflation mechanism has a gaseous chamber extending in the same direction as a bottom panel. The gas diffusion mechanism includes a base, a partition wall and at least one diffusion member. The base masks an outlet of the gaseous chamber to form an auxiliary gaseous chamber. The partition wall extends perpendicularly to the bottom panel to form a vertical first gas channel in communication with the auxiliary gaseous chamber. The diffusion member and the partition wall together define a second gas channel. The partition wall has at least one gap whereby the first gas channel and the second gas channel are in communication with each other.

## Claims

### Claim 1

A substrate container with enhanced flow field therein, comprising:
a box having a front cover and a back panel opposing the front cover, a bottom panel connecting the front cover and the back panel, and a top panel connecting the front cover and the back panel, wherein the front cover, the back panel, the bottom panel and the top panel together define an internal receiving space;
at least one offset inflation mechanism disposed outside the internal receiving space and having a gaseous chamber extending in the same direction as the bottom panel, wherein an inlet is disposed at an end of the gaseous chamber, wherein the inlet and the box are disposed on two opposing sides of the gaseous chamber, respectively, wherein plural outlets penetrating the bottom panel are disposed at another end of the gaseous chamber, wherein the plural outlets are positioned proximate to the back panel; and
at least one gas diffusion mechanism adjoining the back panel and comprising two a-bases, two partition walls and two diffusion members, wherein the two bases masks the plural outlets to thereby form an auxiliary gaseous chamber, the gaseous chamber and the auxiliary gaseous chamber are separated by the bottom panel, wherein the two partition walls extends perpendicularly to the bottom panel and a vertical first gas channel is formed at least partially by the two partition walls, wherein the first gas channel is in communication with the auxiliary gaseous chamber, wherein the two diffusion members are respectively disposed on at least one side of the two partition walls, wherein a first one of the two second gas channels is formed by a first of the two diffusion members and a first of the two partition walls, wherein a second of the two second gas channels is formed by a second of the two diffusion members and a second of the two partition walls, wherein one of the two partition walls has a gap whereby the first gas channel and one of the two second gas channels are in communication with each other,
wherein, an arrangement direction of the first gas channel and the two second gas channels is parallel to a surface of the back panel, the first gas channel and the two second gas channels are distributed in parallel and adjacent to the back panel, and a first of the two second gas channels is arranged on an opposite side of the first gas channel from a second of the two second gas channels.

### Claim 2 (depends on 1)

The substrate container with enhanced flow field therein according to claim 1, wherein each of the two second gas channels and the auxiliary gaseous chamber are not in direct communication with each other.

### Claim 3 (depends on 1)

The substrate container with enhanced flow field therein according to claim 1, wherein a surface of the two diffusion members facing the front cover has a plurality of through holes, such that gas from the first gas channel goes to the front cover via the through holes.

### Claim 4 (depends on 1)

The substrate container with enhanced flow field therein according to claim 1, wherein the two partition walls and the two diffusion members are integrally formed.

### Claim 5 (depends on 1)

The substrate container with enhanced flow field therein according to claim 1, wherein the gap is disposed between one of the two partition walls and the back panel.

### Claim 6 (depends on 1)

The substrate container with enhanced flow field therein according to claim 1, wherein the two partition walls and the back panel are integrally formed.

### Claim 7 (depends on 1)

The substrate container with enhanced flow field therein according to claim 1, wherein the back panel, two partition walls and the two diffusion members are integrally formed, and the gap penetrates one of the two partition walls.
