You have to specify the 'YTick' values specifically:

The code:

x = linspace(0, 5);                             % Create Data
y = 10.^(randi([-20 -4], 1, 100));              % Create Data

figure(1)
semilogy(x, y)
grid
yts = 10.^round(-20:-4);                        % Generate Desired Y-Tick Values
set(gca, 'YTick',yts)                           % Set Y-Tick Values
axis tight

The plot:
