Let f (x)= x d+ λ x d− 1+ μ x be a trinomial in F q [x] and χ m be a character of order p m. If p> 2 d and p≡− 1 (mod d), we obtain the q-adic Newton polygon of L⁎(f, χ m, s). For μ= 0, we give the q-adic Newton polygon of L⁎(f, χ m, s) if p> 2 d under some conditions. We prove that Z p-tower given by x d+ λ x d− 1+∑ p n f n (x) is slope stable under certain conditions.
