Holding a total of four patents, his innovative work focuses on the development of advanced materials and methods for enhancing transistor performance.

Latest Patents

Among Johan's notable patents is the "Self-aligned Embedded SiGe Structure and Method of Manufacturing the Same". This invention describes a method for creating a low energy surface by conducting a high-temperature anneal on the surfaces of trenches adjacent to a gate stack. During this process, the semiconductor layer material undergoes reflow, resulting in a crystallographic surface that is oriented at a non-orthogonal angle relative to the surface normal. The invention cleverly allows for the selective growth of a lattice mismatched semiconductor material within these trenches, forming integrated lattice mismatched segments in the source and drain regions of a transistor. These segments can be in-situ doped, effectively reducing the risk of punch-through. Additionally, the patent discusses an alternative method combining intrinsic selective epitaxy and ion implantation to produce deep source and drain regions.
