The Czech Republic ended the medal hopes of host Turkey on Friday by marching into the last four.
The Czechs, silver-medal winners two years ago, clinched an 86-60 triumph to remain unbeaten in this event.
Despite playing in front of a hostile crowd in Ankara, Jan Bobrovsky's team had too much class and now meet Spain in the semi-finals.

With the two sides averaging over 70 field goal attempts per game, the contest was always going to be a high scoring affair.
Turkey's plan, just as in all their other games, was to get out on the break and run as much as possible. However, against a Czech Republic team featuring plenty of heavy offensive artillery, Turkey found it difficult to keep up and quickly fell behind.
Superstar center Eva Nemcova led the winners with 20 points, 16 of those coming in the first half, while she held down 11 rebounds.
The Czechs outrebounded Turkey 52 to 30 and Bobrovsky's side led by 20 points at the end of the third quarter to cruise to victory.
Similar to other games, several players had a hand in the victory.
Eva Viteckova netted 19 points while team-mate Jana Vesela grabbed 14 rebounds.
The victory means the Czechs have qualified for the FIBA World Championship Women 2006 in Brazil.
Turkey have fully justified their place in the EuroBasket Women and still have a chance to reach Brazil but they must finish fifth with five qualifying places on offer for European teams.
On Saturday the Czechs take on Spain, who they last faced as the two teams opened their 2004 Olympic campaign.
Spain's Laia Palau hit a three pointer at the buzzer to take the game into over-time, when her side managed to clinch victory.
