<p>The present invention provides a siloxane polymer family comprising siloxane polymer made from: (a) a strongly absorbing compound; (b) at least one silane having good leaving groups; and (c) at least one silane having good leaving groups that is different than (b); wherein the siloxane polymer family exhibits a relationship that is concave/convex or is located in the region enclosed by a concave/convex relationship for the ratio of (a) to (b) to (c) and the siloxane polymer's extinction coefficient k value. These siloxane polymers are preferably used as spin-on glass compositions for films in the microelectronics applications.</p> |
