Patent number: 6562694Abstract: A method of manufacturing a semiconductor device including semiconductor elements having semiconductor zones (17, 18, 24, 44, 45) formed in a top layer (4) of a silicon wafer (1) situated on a buried insulating layer (2). In this method, a first series of process steps are carried out, commonly referred to as front-end processing, wherein, inter alia, the silicon wafer is heated to temperatures above 700° C. Subsequently, trenches (25) are formed in the top layer, which extend as far as the buried insulating layer and do not intersect pn-junctions. After said trenches have been filled with insulating material (26, 29), the semiconductor device is completed in a second series of process steps, commonly referred to as back-end processing, wherein the temperature of the wafer does not exceed 400° C. The trenches are filled in a deposition process wherein the wafer is heated to a temperature which does not exceed 500° C.Type: GrantFiled: December 21, 2000Date of Patent: May 13, 2003Assignee: Koninklijke Philips Electronics N.V.Inventors: Ronald Dekker, Henricus Godefridus Rafael Maas, Cornelis Eustatius Timmering, Pascal Henri Leon Bancken
