Modular Kitchen in short means completely fabricated components reach your home and are installed (fixed in day or two). Before you know, your kitchen Platform and many other parts are ready to use. You get a Platform top made out of Wood.
In Semi Modular kitchen, people make Platform Top out of some stone ( mainly Granite). Making Granite involves Civil work ( involves Cement Sand etc ) . Once your Platform top is ready, inner components like Trolley etc are brought and installed inside.
