Patent number: 11666951Abstract: A wafer handler cleaning tool may include a scraping device positioned near semiconductor equipment (e.g., a cooling plate, a semiconductor processing device, and/or the like) such that the scraping device removes foreign objects, debris, and/or other types of matter from the underside of the wafer handler when the wafer handler loads a wafer into the semiconductor equipment and/or unloads the wafer from the semiconductor equipment. Moreover, the wafer handler cleaning tool may include a negative pressure device to draw the removed foreign objects, debris, and/or other types of matter away from the scraping device and toward a filtration device such that the filtration device captures the removed foreign objects, debris, and/or other types of matter.Type: GrantFiled: July 10, 2020Date of Patent: June 6, 2023Assignee: Taiwan Semiconductor Manufacturing Company, Ltd.Inventors: Heng-Wei Liao, Kuo-Hua Wang, Ming-Tsai Kuan

Patent number: 7720564Abstract: A transport system. The transport system comprises a first interbay component, a second interbay component, a plurality of intrabay components, and a route controller. The first and second interbay components transport the vehicles between the tool bays. Each of the intrabay components, linked with the second interbay component, transports the vehicles within one of the tool bays. Additionally, the intrabay component does not link with the first interbay component directly. The route controller estimates a transport cost for transporting the vehicle via the second interbay device, and determines whether the vehicle is to be transported via the first or second interbay component according to the estimated transport cost.Type: GrantFiled: February 21, 2006Date of Patent: May 18, 2010Assignee: Taiwan Semiconductor Manufacturing Co., Ltd.Inventors: Kuo-Hua Wang, Hsing-Fu Wang

Publication number: 20100088449Abstract: A detecting system includes a slot, a controller and a power source terminal. The slot includes a first detecting pin and a second detecting pin. The first detecting pin is electrically connected to a detecting voltage terminal. The second detecting pin is connected to ground. The controller is electrically connected to the first detecting pin. The controller receives a high level voltage signal from the first detecting pin when an expansion card is not detected. The power source terminal is connected to the slot under control of the controller. On the condition that the first detecting pin is electrically connected to the second detecting pin. The controller receives a low level voltage signal from the first detecting pin. The controller is then triggered to connect the power source terminal to the slot to supply power to the expansion card.Type: ApplicationFiled: May 12, 2009Publication date: April 8, 2010Applicant: HON HAI PRECISION INDUSTRY CO., LTD.Inventors: KUO-HUA WANG, MEI-HUI CHEN

Publication number: 20050187647Abstract: The present invention relates to an apparatus and method for processing the flow of semiconductor wafers through a furnace tool having a front-opening unified pod (FOUP) material handling system. The invention provides for an automated control flow to realize greater efficiency and assure process quality. In one aspect of the invention the wafer batch completing its operation is discharged simultaneous with the charging of the next batch. Essentially the operation takes place by overlapping processing operations. An embodiment of the invention includes a process comprising the steps of: providing a first batch of semiconductor material, and loading the first batch into a carrier which transports the first batch into a semiconductor manufacturing process, and while the first batch undergoes the process, forming a second batch of semiconductor material, and pausing a second batch process operation until the first batch completes processing, to reduce the idle time of said process.Type: ApplicationFiled: February 19, 2004Publication date: August 25, 2005Inventors: Kuo-Hua Wang, Shun-An Chen

Patent number: 6913270Abstract: A roller skate shoe includes a shoe body and a roller mechanism. The roller mechanism is consisted of a housing, a roller, a roller axis, press rods, elastic members and a butting assembly. An accommodating chamber is disposed below a rear end of an insole of a shoe body, and the rear end of the insole is disposed with an insertion opening penetrating a rear end of the accommodating chamber, thereby placing the roller mechanism in the accommodating chamber. To put the aforesaid structure in use, the roller is extended or retracted through actions of the butting assembly and the elastic members of the roller mechanism, thereby providing a user with choices of using the roller skate shoe for skating or walking.Type: GrantFiled: June 16, 2003Date of Patent: July 5, 2005Inventor: Kuo-Hua Wang
