Hello Student

Generally any Masters course is of two year which have 3 semesters and 1 internship . This phenomenon is accepted world wide and so in India so ,but certain countries in europe and certain states in America and Australia are offering an Mtech degree of 1 yr . The reason being that this courses are for people who have atleast an year or two years of experience within the same domain and have appropriate knowledge in the field so they are okay with one year master courses. In india though you have a bacholers degree and a job  , there is no options for single year masters program but there are options like apprentinceship or distance learning.
