[0069] Example 1:

[0070] The semiconductor cleaning fixture provided by this utility model, such as Figures 1-5 As shown, it includes a fixture box 100 and a handle structure 110. The handle structure 110 is provided on the fixture box 100. The fixture box 100 can be gripped through the handle structure 110, and the fixture box 100 and the product can be placed into the cleaning machine for cleaning. During cleaning, the fixture box 100 is moved up and down or back and forth and left and right to complete the cleaning.

[0071] The fixture box 100 includes a left side plate 120, a middle side plate 130, a right side plate 140, a rear end plate 150, and a front end plate 160. The left side plate 120, the middle side plate 130, and the right side plate 140 are all arranged in parallel and are connected between the rear end plate 150 and the front end plate 160. The two side walls of the middle side plate 130 are respectively arranged opposite to the left side plate 120 and the right side plate 140.

[0072] Several placement grooves 170 are provided on both sides of the left side plate 120, the middle side plate 130, and the right side plate 140, so that products can be placed between the left side plate and the middle side plate 130, and between the middle side plate 130 and the right side plate.

[0073] Furthermore, the starting and ending ends of the placement groove 170 are completely open and unobstructed, which ensures that the product can fully contact the cleaning fluid during ultrasonic cleaning, thereby improving the cleaning effect of the product and facilitating the cleaning of the fixture itself.

[0074] Furthermore, an isolation protrusion 180 is formed between two adjacent placement grooves 170, and the isolation protrusion 180 is provided with a perforated through hole 190.
