During Maternity the women is entitled to maternity benefit under the Maternity Benefit Act, her active services hold in abeyance during that time, so the period as we call it is "Vacuum". So no ESIC or PF is deducted. As Payment of Wages Act is supplemented by Maternity Benefit Act for that period.
Now Sick leave, under ESIC there is specific provision for Sick Leave and Sickness Benefit. But keeping it aside ESIC is deducted on wages that an employee earns in lieu of work. if you are paying him sickness benefit, that is not wages. So over and above the payment for work there is no deduction as that is not wages but benefit.
