TMAH chemical etch rate at ambient temperature is sensitive to environmental conditions. Increase N_2 concentration in chemical would reduce O_2 partial pressure and leads to higher poly etching rate. Other gas such as CO_2 have the opposite effect and makes ER trend down to zero, probably ...
所以这个一般需要Wet Etch前后各一步Thermal来。如果一步到位对小线宽的Gate控制不好。因为反应过程中是Si扩散到界面与Ti反应。这样就会有一定量的横向反 应。 Polycide的Rs会比较大一些,但是Thermal下比较稳定。以上在0.35-0.6甚至0.8um都有在用。0.25及其以下用CoSi2,对线宽控制比较好,因为Co与Si反应的时候,是Co...

Using conventional silicon dioxide as sacrificial layer material, the release of the functional silicon structures is achieved by removal of the silicon dioxide in a hydrogen fluoride (HF) based etchant (either wet or vapor phase). Great care must be taken to prevent sticking of mechanical sensor...

Etching in gold etchant allows the replication of this pattern in gold (Xia et al. 1996). This method allows the direct transfer of a micrographic pattern present on the flexible PDMS layer to be replicated on any substrate without expensive microscale definition processes like UV lithography. ...

A photoresist layer is formed over a portion corresponding to the gates. A first etch forms the gate structure. Following removal of the photoresist, a second etch completely removes the BARC. The silicon dioxide layer can be removed by a subsequent wet etch with HF....
