Officially spun off from the National Research Council of Canada (NRC) in 1995,[1] it provides Technology Computer Aided Design (TCAD) tools for semiconductor device and process simulations.

[3] By adding the ability to model quantum well active regions, LASTIP was also a significant step-up from earlier comparable efforts such as Hitachi's HILADIES.

[4] As early laser diode TCAD tools were primarily developed by individual researchers for their own use, Crosslight claims that LASTIP's commercialization makes them first-to-market in this field.

In January 2010, Crosslight entered into a partnership with Acceleware with the intention of producing greater speed in thin film solar cell and image pixel sensor simulations.
