My TOEFL score is below the minimum required, but it is close to 100. In this case, can I get a chance for admission? ( I have worked for 7 years in my country and published 2 papers. ) Berkeley is my dream school, but I heard that it is hard to get admission from Berkeley Law.

Just apply and see how it goes. They review every application holistically and the TOEFL is only 1 factor among many others.

The TOEFL requirement is not a strict one (except for the Chicago). If you have 2 or 3 points less than recommended by law school, it will negatively affect you chances for admission, but will not determine whether you will be admitted or not per se. If you have a strong application i.e.: excellent GPA, working experience, nice personal statement and recommendation letters from respected recommenders, you will have a better chance to be admitted than candidate with higher TOEFL score (say 110), but with average credentials.
It also depends on the subsections distribution. Generally for law school it is better to have high scores in reading, listening and writing than in speaking.
