Title: Method for forming shallow trench isolation in integrated circuits
Inventor: TSAI SHING-CHUAN
IPC: H01L21/76
Filed: 1998-01-20
Granted: 2001-01-21
Abstract: A method for forming shallow trench isolation in integrated circuits is provided, which first forms a first silicon oxide layer, a hard mask, and a second silicon oxide layer on the substrate sequentially. Then, the photolithography and etching technique is used to form a shallow trench. A thermal oxidation process is performed followed by forming a third silicon oxide layer. The third silicon oxide layer is removed except the shallow trench region. Then, a fourth silicon oxide layer is formed to fill the shallow trench, wherein the deposition rate of the fourth silicon oxide layer on the third silicon oxide layer is faster than that on the second silicon oxide layer. The silicon nitride layer functions as the etch stop for the etching back process.

Title: Biaxial orientation molding machine
Inventor: SUZUKI SABURO
IPC: B29C49/42
Filed: 1998-01-26
Granted: 2001-05-28
Abstract: A biaxial orientation molding machine (1) is constructed such that supplying and heating of preforms, biaxial orientation molding and a recovering action of molded products are successively carried out by conveying a preform carrier pallet (7) along a conveying path (6) having a closed configuration. The conveying path (6) is a three-dimensional one such that a second conveying path portion (64) for returning to a preform supplying unit (2) a preform, which is made empty after taking out of a molded product, is formed at a much lower position than a first conveying path portion (62), in which heating and biaxial orientation molding are carried out. The second conveying path portion (64) is allowed to pass beneath an underside of a clamping mechanism (41) of a biaxial orientation molding section (4) and is therefore made linear. Accordingly, it is possible to shorten the entire length of the conveying path, realize small sizing and compactness of the machine and to improve a processing efficiency.

Title: Cleaning solution replenishing method for wafer cleaning tank
Inventor: CHANG CHENG-CHUNG
IPC: B08B3/04
Filed: 1998-10-29
Granted: 2001-06-23
Abstract: This invention provides a cleaning solution replenishing method for wafer cleaning tank, which primarily utilizes two liquid level indicators installed in the outer tank of cleaning tank. For each indicator, there is a corresponding sensor. When the liquid level is below the lower level indicator, cleaning solution is replenished through the detection of the corresponding sensor. The amount of cleaning solution added is controlled by the higher level indicator, that is, the liquid level will not be higher than the position monitored by the higher level indicator after replenishing. Moreover, the setting of the two liquid level indicators has to ensure the concentration of the cleaning solution in an allowable range during replenishing process. Through the use of this invention, the concentration of cleaning solution can be maintained in an adequate range and thus it will not impact the wafer cleaning effectiveness and also precisely control the amount of solution added. This method can reduce the replenishment amount of cleaning solution and time for replacing acid solution.

Title: Method of forming a shallow trench isolation structure
Inventor: CHEN SHIUE-JUNG
IPC: H01L21/76
Filed: 1998-11-04
Granted: 2000-05-11
Abstract: This invention provides a method of forming shallow trench isolation. A polysilicon layer is formed on a masking layer and then a chemical mechanical polishing (CMP) is performed to completely strip the polysilicon layer. Since the polishing rate of the polysilicon is faster than that of the oxide layer in the trench, dishing effect can be prevented. This invention also can suit the reversed mask process. The insulating layer on the active area is partially removed and the polysilicon layer is used as an etching stop layer.. Because the insulating layer is partially stripped, the CMP step spends less processing time such that the dishing effect can be avoided.
