CONSTITUTION:Being practicable for one of manufactures of semiconductor that is formed on a semiconductor substrate 1 by coating a phosphorous silicate glass (PSG) 5, the heat treatment of PSG 5 is carried out in an atmosphere containing boron. For example, a layer insulation film 5 consisting of gate electrodes 2, AsSG film 3, first layer interconnections 4 of multicrystal Si and the like is laminated in sequence on the semiconductor substrate l made of silicon and others. Under these conditions, phosphorous density of the layer insulation film 5 is 8 wt.% and its film has stepped portions prior to carrying out a reflow process as shown by a dotted line. And then, the atmosphere used in the reflow process uses N2 and O2 as carrier gases, to which BBr3 is added in a state of particulate form and when the heat treatment is carried out at a temperature of 850 deg.C for a half hour, PSG layer 5 is melted down and is moderately transformed into a flat surface form shown by a, solid line from the stepped state shown by a dotted line.

Title: Printed-wiring board
Inventor: KOGURE KAZUYA
IPC: H05K3/34
Filed: 1996-05-21
Abstract: PROBLEM TO BE SOLVED: To avoid the need to remove a large amount of solder by a method wherein the land part with one end of a surface mount components soldered thereto is coated with a resist film while the width of the land part not coated is made narrower toward the other end of the surface mount component. SOLUTION: Since the surface mount component 11 is deformed upward by the surface tension of the solder 12 on the land part 9, this part 9 can be removed from a printed-wiring board 8. In such a constitution, the solder 12 is rounded by the surface tension thereof when it is applied to the land 9 so that the solder on the crest part of an isosceles triangle may be moved in the direction of the wider width part. Accordingly, the quantity of the solder on the land part 9 to displace up to the position required for the removal of the surface mount component 11 can be notably reduced.
