  • Publication number: 20240074134
    Abstract: An integrated circuit includes transistor. That transistor is manufactured using a process including the following steps: forming a first gate region; depositing dielectric layers accumulating on sides of the first gate region to form regions of spacers having a width; etching to remove a part of the deposited dielectric layers accumulated on the sides of the first gate region to reduce the width of the regions of spacers; performing a first implantation of dopants aligned on the regions of spacers to form first lightly doped conduction regions of the transistor; and performing a second implanting of dopants to form first more strongly doped conduction regions of the transistor.

  • Publication number: 20230223358
    Abstract: Integrated circuits are supported by a semiconductor substrate wafer. Each integrated circuit includes an electrically active area. A thermally conductive protective structure is formed around the active areas of the various integrated circuits along scribe paths. The protective structure is located between the electrically active areas of the integrated circuits and a laser ablation area of the scribe paths. Separation of the integrated circuits is performed by scribing the semiconductor substrate wafer along the scribe paths. The process for scribing includes performing a laser ablation in the laser ablation area and then performing one of an etching or a physical scribing.
