摘要:
A cleaning method following an opening etching is provided. First, a semiconductor substrate having a dielectric layer is provided. The hard mask layer includes at least a metal layer. The opening etch is then carried out to form at least an opening in the dielectric layer. A nitrogen (N2) treatment process is performed to clean polymer residues having carbon-fluorine (C—F) bonds remained in the opening. Finally, a wet cleaning process is performed.

A patterning method is provided. A patterned photoresist layer is formed on a bottom anti-reflective coating (BARC), having therein an opening exposing a portion of the BARC. The patterned photoresist layer is treated with a first plasma-generating gas including a fluorocarbon species to form a polymer layer on the surface of the PR layer and the sidewall of the opening. The patterned photoresist layer is used as a mask to etch the BARC with a second plasma-generating gas, which includes Ar and H2 but no fluorocarbon species or oxygen-containing species, to remove the exposed portion of the BARC.
摘要:
A process of automatically translating a high level programming language into a hardware description language (HDL), which can use a three-stage translation mechanism to generate the HDL codes corresponding to the functions described by the high level programming language. The first stage translates source codes coded by the high level programming language into an extended activity diagram (EAD). The second stage translates the EAD into a hardware component graph (HCG). The third stage generates the respective signal connections of HDL components according to all edges of the HCG, and outputs an HDL entity and architecture to a file in a string form, thereby completing the entire translation.
摘要:
An HCG to HDL translation method, which can automatically generate VHDL codes. The method reads a hardware component graph (HCG) to find a start node and obtain a corresponding hardware component subgraph of the start node, analyzes all information of the start node to thereby add input and output components and generate a VHDL entity, determines types on all nodes of the hardware component, graph to thereby generate corresponding VHDL components and write associated information in a VHDL architecture, generates corresponding signal connections of VHDL components in accordance with edges of the hardware component graph, and outputs the VHDL entity and architecture to a file in a text form.
