PURPOSE: A method for etching polysilicon in a semiconductor fabrication process is to allow a polysilicon to be etched uniformly during a semiconductor fabrication process and prevent damage of oxide layer. CONSTITUTION: A method for etching polysilicon in a wafer having a first oxide film, a ...
A process for etching a substrate and removing etch residue deposited on the surfaces in the etching chamber has two stages. In the first stage, an energized first proces
Lastly,wet etchingis an importantdevice fabricationprocess that complements dry etching techniques. Generally, dry etching processes—reactive ion etching (RIE), for example—can be highlyanisotropic, an ideal characteristic for producing vertical profiles. However, due to the strong physical component in...
array of conductive stips which can be used as a cathode for an electroluminescent display device. In combination, both anode and cathode can be fabricated for a display device without the need for photolithography, which is particularly advantageous for the fabrication of large area display devices...
The aim of the etching process is to remove material from the IC surface in the areas left uncovered after photoresist development. For most patterning steps, dry (plasma) etching is now the standard procedure, while “wet” etching using liquid chemicals is still used to clean wafers. The ma...
In semiconductor device fabrication, etching refers to any technology that selectively removes layers of material from a wafer’s surface, forming structures with specific depths and shapes. Etching is the process step that takes the design information from masks and transfers it into regions on the...
Samco’s open load RIE systems and load lock RIE systems have a wide process window for plasma etching of various materials (silicon, dielectrics, compound semiconductors, metals, polymers and photoresist). The cassette loading RIE systems improve process throughput for device fabrication. RIE System...
MEMSdesign and fabrication is highly complex in the sense that the fabrication process heavily depends on the design, unlike IC fabrication which has a standard set of processes. A slight change inMEMSdesign can alter its fabrication steps to a large extent. For example, setting device parameters...

Often shortened to:photolitho 2.(Electronics)electronicsa process used in the manufacture of semiconductor devices, thin-film circuits, optical devices, and printed circuits in which a particular ...
Besides, compared with carbide MXenes, nitride MXenes require more precise adjustment of etching parameters dur- ing the preparation process, because the M–N bond may be broken under the attack of HF etchant [57]. However, harsh reaction environment could result in the form...
