Schengen visas may be single-, double- or multiple-entry and allow the holder to spend no more than 90 days in Finland and other Schengen countries within a 180-day period (calculated from the holder’s first arrival in the Schengen area).
If you require a visa to enter Finland and are planning to stay for more than 90 days, then you must apply for a Finnish visa, not a Schengen visa. The European Commission has a short-stay Schengen visa calculator at https://ec.europa.eu/home-affairs/content/visa-calculator_en, which you can use to calculate whether you fulfil the general 90 days/180-day rule or not, and to estimate for the maximum length of stays in the future from the intended date of entry on the basis of previous entry and exit dates.
