Title: Manufacture method of shallow trench isolation
Inventor: JU JR-SHIUN
IPC: H01L21/762
Filed: 1998-10-21
Granted: 2000-11-01
Abstract: A method of manufacturing a shallow trench isolation. After forming a spacer on a sidewall of a patterned mask layer and a pad oxide layer, a trench is formed by using the mask layer and the spacer as a hard mask and etching. A buffer layer conformal to the surface of the device is formed on the substrate before the trench is filled with an insulating layer. Accordingly, the spacer, during the subsequent etching process of pad oxide layer removal, can prevent a recess from being produced at the edge of the trench such that kink effect is avoided. The buffer layer not only prevents oxidation being occurred on the sidewall of trench during densification of insulating layer under an oxygen environment, but also avoids lateral etching lost of insulating layer when the pad oxide layer is removed by etching.

Title: Metal etching in semiconductor manufacturing process
Inventor: TSAI WEI-REN
IPC: H01L21/3213
Filed: 1999-05-31
Granted: 2000-11-11
Abstract: There is disclosed a metal etching step in a semiconductor manufacturing process. The metal layer etching of the present invention first utilizes plasma formed by Cl2 to perform a dry etching process and, at the same time, a proper amount of CHF3 is added thereto. Next, in a major aluminum alloy etching process, Bl3 and N2, besides the Cl2, are added to enhance the anisotropic etch capability. In the present invention, the volume ratio of the reaction gases Cl2/BCl3 is increased to avoid the microloading effect of the metal wires resulted in the area having different wiring densities. At the same time, the pressure on the reactor is also increased, but the bias power is decreased, so as to have an overall anisotropic etch effect. Then, an over-etching step is executed. Next, a sidewall passivation process and an anti-corroding process are performed. Finally, the photoresist is stripped off and wet cleaning is performed to complete the metal layer etching process in accordance with the present invention.

Title: Device and method for storing information
Inventor: DENG XIAOJUN
IPC: H01L21/8247
Filed: 2000-01-26
Granted: 2001-05-16
Abstract: The memory element of the present invention utilizes a substrate, a first conductive connection, a second conductive connection, and an ionic layer. The substrate includes a source region, a drain region, and a channel region, which is disposed between the source region and the drain region. The ionic layer includes ions and is coupled to the substrate. The first connection is coupled to the source region, and the second connection is coupled to the drain region. An electrical field is applied through said ionic layer such that the ions in the ionic layer move. When the memory element is to exhibit a logical high state, the polarity of the electrical field causes the ions to move toward the channel region. This pulls the electrons in the source and drain regions into the channel region making the channel region conductive. When the memory element is to exhibit a logical low state, the polarity of the electrical field causes the ions to move away from the channel region. As a result, the channel region becomes non-conductive, and the first conductive connection is, therefore, insulated from the second conductive connection.
