IPC: H01L21/265
Filed: 2000-12-19
Granted: 2002-06-21
Abstract: This invention provides a method to increase wet etching rate of dielectric layer using ion implantation. Firstly, a dielectric layer is formed on a semiconductor substrate, which is followed by coating a photoresist layer on the surface of the dielectric layer. A dry etching process is performed on the exposed part of the dielectric layer using the photoresist layer as a etching mask to form an opening pattern. In order to prevent damage on the semiconductor substrate by dry etching, there is residual dielectric layer remained at the bottom of the opening pattern. Then, an ion implantation process is carried out on the residual dielectric layer at the bottom of the opening pattern to result in a loose structure. A wet etching process is conducted on the residual dielectric layer to thoroughly remove the dielectric layer. Compared with the untreated dielectric layer, the ion implanted dielectric layer has more than two times of wet etching rate.

Title: Servo-driven automatic mold adjusting and controlling method
Inventor: LIOU SHING-CHANG
IPC: B29C45/76
Filed: 2001-12-19
Granted: 2004-10-21
Abstract: Disclosed is a servo-driven automatic mold adjusting and controlling method, where after the elbow of a mold clamping unit of a servo driven injection molding machine is expanded, the claming force is about 0 if the movable mold plate happens to contact the stationary mold plate. If the elbow is receded for a distance, and the moving an adjusting mold plate and the movable mold plate forwards for another distance, and the adjusting mold plate and the movable mold plate are then affixed, the movable mold plate can no longer move forwards at this time even if the elbow is expanded because the movable mold plate has contacted the stationary mold plate. Accordingly, the feeding distance of the motor will cause deformation of the tie bards, thereby providing the mold with a mold-clamping force.
