Background

In the process of converting semiconductor materials into useful devices, most processes use chemical solutions, and a large amount of cleaning of the wafer is involved. The existing wafer flushing flower basket generally comprises two parts, namely a circular leakage groove and a flower basket handle, wherein the leakage groove is horizontally arranged and is vertical to the handle, the flower basket is called a flat-bottom flushing flower basket, the circular leakage groove is used for placing a wafer, the flat-bottom flushing flower basket enables a support rod to be held by a hand and can be cleaned in a rotating mode by 360 degrees, chemical liquid is completely extracted after being washed, and a culture dish is placed for overflowing flushing; the other is a vertical flower basket, 3 pieces of flower can be operated at one time, but the flower basket can only be placed in a culture dish to be flushed by overflowing water. The inclined flower basket can meet the requirement of flushing, but the inclined process is easy to cause unevenness in the operation process of the corrosive liquid in consideration of the angle, so that the inclined process needs to be optimized.

Current flat bath basket of flowers or vertical basket of flowers follow chemical liquid and draw the back out, and the basket of flowers is placed and is washed in the culture dish, only trades three cups of water, and whole journey adopts the overflow bath mode, duration 5 minutes, and rivers do not directly wash the wafer to rivers if the washing effect that less does not reach 5 minutes, lead to the chemical liquid very easily to remain on the wafer, unclean including the culture dish also can bring dirty, influence the appearance, performance and the reliability of product.

SUMMERY OF THE UTILITY MODEL

The utility model improves the problems, namely the technical problem to be solved by the utility model is to provide the inclined flat-bottom flower basket fixing support which is simple in structure and convenient to use, can better clean culture dishes and wafers, and improves the appearance, performance and reliability of products.

The flower basket comprises an inclined base and an inclined plane arranged on the inclined base, wherein a semicircular gland is arranged on one side of the inclined plane and used for limiting one half of the flat-bottom flower basket, a fixed seat is arranged on the upper portion of the other side of the inclined plane, and a pulley shaft extending to the lower portion of the side of the inclined plane is hinged in the fixed seat and used for pressing the other half of the flat-bottom flower basket.

Furthermore, a through hole is formed in the middle of the inclined base.

Furthermore, the fixed seat is connected with the upper end of the pulley shaft through a positioning pin.

Furthermore, the semicircular gland is fixed on the inclined base by adopting a positioning piece.

Furthermore, a fixing screw for extending to the inside of the fixing seat to prop against the positioning pin is arranged above the fixing seat.

Furthermore, the included angle between the inclined plane and the lower bottom surface of the inclined base is 30 degrees.

Furthermore, a semicircular notch is formed in the inner side of the semicircular gland, a blocking body is arranged above the semicircular notch, and a limiting groove formed by the blocking body and the semicircular notch is matched with the shape of the flat-bottom flower basket at the position.

Compared with the prior art, the utility model has the following beneficial effects: the device is reasonable in design and simple in structure, after the flat-bottom flushing flower basket or the vertical flower basket is extracted from the chemical liquid, the flat-bottom flower basket is placed in a culture dish to be washed for 2 times, then the pulley shaft is upwards pulled, the flat-bottom flower basket is clamped in the limiting groove, the pulley shaft is pressed downwards, and the round wafer can be better washed clean by directly washing for several minutes by using the water faucet, so that the problem of uneven corrosion of the round wafer is solved; meanwhile, the inclined plane of the inclined seat is arranged, so that the problem that the product is cracked due to overlarge impact force of water flow can be avoided.

Detailed Description

The utility model is described in further detail below with reference to the drawings and the detailed description.

Example (b): as shown in fig. 1-5, in the present embodiment, a tilting type flat-bottom flower basket fixing support is provided, which includes a tilting base 1 and a tilting plane 11 disposed on the tilting base, a semicircular gland 2 is disposed on one side of the tilting plane for clamping one side of a flat-bottom flower basket 8, a fixing seat 3 is disposed on the upper portion of the other side of the tilting plane, and a pulley shaft 4 extending to the lower portion of the tilting plane is hinged in the fixing seat for blocking the other side of the flat-bottom flower basket to prevent the flat-bottom flower basket from dropping out and affecting the operation.
