Patent number: 6656668Abstract: A process method of using excimer laser for forming micro spherical and non-spherical polymeric structure array includes a photomask which has a selected curved pattern formed thereon. The curved pattern has non-constant widths along a straight line direction.

The polymeric material thus may be etched to different depth to form a three dimensional pattern desired. By projecting and etching the polymeric material two times at different directions or through different photomask patterns, a sphere like or non-sphere like surface of micro array structure may be obtained.Type: GrantFiled: August 23, 2001Date of Patent: December 2, 2003Assignee: Industrial Technology Research InstituteInventors: Hung-Yin Tsai, Cheng-Tang Pan, Min-Chieh Chou, Shih-Chou Chen, Yuh-Sheng Lin

Patent number: 6003833Abstract: An integrated micro pressure-resistant flow control module in which, when a fluid enters the integrated module past a pressure-resistant fluid channel and a suspended microstructure into a thermally-driven microvalve zone, the latter utilizes heat actuation to drive a silicon microbridge with mesa to open a linear proportional flow microvalve. A pressure-resistant flow sensing unit is disposed before the fluid channel to sense the flow amount. The flow sensing unit has a micro-suspending arm of pressure-resistant material located vertically at the fluid entrance of the module. The momentum of the fluid is thereof vertical to the micro-uspending arm, and the flow value is obtained by the deflection of the micro-suspending arm which changes the resistance value.

Patent number: 5972193Abstract: The present invention uses a glass to act as a substrate. A stencil layer is patterned on the top surface of the substrate. Successively, a copper layer is deposited over the substrate. Next step is to remove the stencil layer. A negative photoresist layer is formed on the copper layer. A negative photoresist layer is processed using a backside exposure of the resist through the transparent substrate. The backside exposure technique uses the self-aligning, conductive copper layer as a mask. A plurality of trenches are then created in the photoresist layer and a second copper layer is electroplated in the trenches to form the planar coils.Type: GrantFiled: October 10, 1997Date of Patent: October 26, 1999Assignee: Industrial Technology Research InstituteInventors: Min-Chieh Chou, Ching-Yi Wu, Star Rey-Shing Huang, Yuh-Sheng Lin
