Publication number: 20240136226Abstract: An ammonium fluoride gas may be used to form a protection layer for one or more interlayer dielectric layers, one or more insulating caps, and/or one or more source/drain regions of a semiconductor device during a pre-clean etch process. The protection layer can be formed through an oversupply of nitrogen trifluoride during the pre-clean etch process. The oversupply of nitrogen trifluoride causes an increased formation of ammonium fluoride, which coats the interlayer dielectric layer(s), the insulating cap(s), and/or the source/drain region(s) with a thick protection layer. The protection layer protects the interlayer dielectric layer(s), the insulating cap(s), and/or the source/drain region(s) during the pre-clean process from being etched by fluorine ions formed during the pre-clean process.Type: ApplicationFiled: January 2, 2024Publication date: April 25, 2024Inventors: Li-Wei CHU, Ying-Chi SU, Yu-Kai CHEN, Wei-Yip LOH, Hung-Hsu CHEN, Chih-Wei CHANG, Ming-Hsing TSAI

Patent number: 9788428Abstract: The invention provides a stacked structure comprising a master circuit board and at least two slave circuit boards. The master circuit board comprises a plurality of connecting seats. Each slave circuit board is equipped with a connector, and defined with a plurality of post-production process areas. Wherein the connector of each slave circuit board is disposed on one of post-production process areas, and inserted into the corresponding connecting seat. When the connector of the slave circuit board must be through other slave circuit boards in order to insert the corresponding connecting seat, the post-production process areas that are disposed on other slave circuit boards and impede the connection between the connector and the corresponding connecting seat will be cut into hollow areas. Accordingly, the connector of the slave circuit board is capable of inserting the corresponding connecting seat through the hollow areas of other slave circuit boards.Type: GrantFiled: April 21, 2016Date of Patent: October 10, 2017Assignee: INNODISK CORPORATIONInventors: Chih-Hsing Chen, Hsiao-Yu Wang
