Title: Method for depositing metal layers using sequential flow deposition
Inventor: MATSUDA TSUKASA
IPC: C23C16/16
Filed: 2004-09-30
Abstract: A method for depositing metal layers with good surface morphology using sequential flow deposition includes alternately exposing a substrate in a process chamber to a metal-carbonyl precursor gas and a reducing gas. During exposure with the metal-carbonyl precursor gas, a thin metal layer is deposited on the substrate, and subsequent exposure of the metal layer to the reducing gas aids in the removal of reaction by-products from the metal layer. The metal-carbonyl precursor gas and a reducing gas exposure steps can be repeated until a metal layer with a desired thickness is achieved. The metal-carbonyl precursor can, for example, be selected from W(CO)6, Ni(CO)4, Mo(CO)6, Co2(CO)8, Rh4(CO)12, Re2(CO)10, Cr(CO)6, and Ru3(CO)12.

Title: Microvalve
Inventor: Pan da-zhi
IPC: B81B1/00
Filed: 2004-11-16
Abstract: The present invention relates to a microvalve suitable for controlling the motion of microfluid, comprising: a front-to-rear connected valve channel, at least one serrated lower stopper installed at the bottom of the inner face of the valve channel, and at least one serrated upper stopper installed behind the lower stopper and at the top of the inner face of the valve channel. By applying the configuration of the present invention, the microfluid is guided by the upper and the lower stoppers and windingly flowing out of the valve channel when the microfluid enters the valve channel from the front. On the contrary, when the microfluid enters the valve channel reversely from the rear, part of the microfluid flow is stopped by the upper and the lower stoppers so as to decrease the flux of countercurrent. Therefore, by the serrated asymmetry of the upper and the lower stoppers, microfluid with different directions are affected by different degree of drag force, so as to confer the microvalve of the invention with the effect of check valve.
