Thomas J. Krehbiel is a graduate electrical engineer with a Masters' in solid state semiconductor and device physics. During his career in the semiconductor industry, he did IC circuit design, IC device design, managed a parametric test area, managed a CIM group, and worked in a RET (Reticle Enhancement Technologies) software development group. Along the way, he created a parametric data analysis system, a wafer tracking system, and a RET processing system.
Thomas has many years of experience managing software development and the hardware and system associated with that development. He has programmed for over 30 years, starting with FORTRAN and ending with his current favorite language Tcl/Tk. As computers changed, Tom worked with mainframes (IBM360), minis (DEC), and desktops (HPUX, Solaris, Linux, Windows).
When he was younger, he enjoyed playing baseball, basketball, handball, tennis, hiking the Grand Canyon, and snow skiing.
