Abstract: A method includes forming a dielectric layer over an epitaxial source/drain region. An opening is formed in the dielectric layer. The opening exposes a portion of the epitaxial source/drain region. A barrier layer is formed on a sidewall and a bottom of the opening. An oxidation process is performing on the sidewall and the bottom of the opening. The oxidation process transforms a portion of the barrier layer into an oxidized barrier layer and transforms a portion of the dielectric layer adjacent to the oxidized barrier layer into a liner layer. The oxidized barrier layer is removed. The opening is filled with a conductive material in a bottom-up manner. The conductive material is in physical contact with the liner layer.

Abstract: A method of fabricating a contact structure includes the following steps. An opening is formed in a dielectric layer. A conductive material layer is formed within the opening and on the dielectric layer, wherein the conductive material layer includes a bottom section having a first thickness and a top section having a second thickness, the second thickness is greater than the first thickness. A first treatment is performed on the conductive material layer to form a first oxide layer on the bottom section and on the top section of the conductive material layer. A second treatment is performed to remove at least portions of the first oxide layer and at least portions of the conductive material layer, wherein after performing the second treatment, the bottom section and the top section of the conductive material layer have substantially equal thickness.

Abstract: An environment risk sorting system includes a plant environment database for storing pieces of environment risk data; a risk sorting server for updating the environment risk data; a managing server coupled with the risk sorting server, wherein, the risk sorting server executes generating through a first risk evaluation module, based on the environment risk data, a first risk evaluation result for each abandoned plant, which produces an environmental site evaluation list, through which, an environmental site evaluation data of each abandoned plant and a on-spot environmental site evaluation data are obtained, updating through a second risk evaluation module succeeding environment risk data based on the environmental site evaluation data of each abandoned plant and hence generating a second risk evaluation result for each abandoned plant, which, in turn, produces an investigation list of each abandoned plant as a basis for follow-up investigation.

Abstract: An environment risk sorting method includes preparing a plant environment database for storing several pieces of environment risk data for abandoned plants; using a first risk evaluation module, based on the environment risk data, to generate a first risk evaluation result for each abandoned plant; using the first risk evaluation result to generate an environmental site evaluation list, which in turn, generates an environment site evaluation data of each abandoned plant and updated environmental risk data; using a second risk evaluation module, based on the environment site evaluation data of each abandoned plant and the updated environmental risk data, to generate a second risk evaluation result for each abandoned plant; and using the second risk evaluation result for each abandoned plant to generate an investigation list as a basis for follow-up investigation.

Abstract: A mobile device for site investigation in real time interaction includes: a digital map display module, a remote data access module, a digital map marking module and a data input module. The digital map display module displays a digital map on a monitor of the mobile device. The remote data access module downloads a vicinity data of a surveyed site from a remote server. The digital map marking module marks a coverage region or a sampling distribution record based on the vicinity data. Further, the data input module displays an editing interface on the monitor of the mobile device for editing the coverage region or the sampling distribution record on the digital map by a user. The remote data access module uploads the edited coverage region or sampling distribution record to the remote server.

Abstract: There is provided a computer software product for processing and outputting a diagram of factory location evaluation, which is executed by a server to implement the following steps: receiving at least a GPS location information and a site investigation information from a mobile device; relating the site investigation information to an area based on the GPS location information and a coverage region information, wherein the coverage region information records a coverage of specific region on a map; and processing the site investigation information and a regional distribution, then generating and outputting a factory location evaluation information to a terminal computer based on the results of the process.
