By Noel Randewich SAN FRANCISCO (Reuters) – Chip gear maker KLA-Tencor Corp said on Tuesday its bookings in the fiscal fourth quarter were close to $895 million or $900 million, higher than expected and helped by demand from contract chip manufacturers. KLA-Tencor said at an event with investors that in the quarter, which ended in June, contract manufacturers, known as foundries, accounted for two-thirds of its business. While bookings topped expectations, Chief Executive Rick Wallace struck a cautious tone about demand, which tends to be lumpy due to a dwindling number of major customers. In April, KLA-Tencor said that it expected bookings in the June quarter in a range between $625 million to $825 million.
